DIBAQ AQUACULTURE RECEIVES THE VISIT OF A GROUP OF ESTONIAN ENTREPRENEURS

Last month, Dibaq Aquaculture received the visit of an Estonian delegation made up of farmers, specialists, scientists and researchers from the world of aquaculture. In total, a group of 15 people who were able to learn, enjoy and contact our facilities to make an ambitious aquaculture growth plan a reality in their country, where Dibaq Aquaculture intends to play a privileged role both in the marketing of food and in consultancy and advice to Estonian entrepreneurs.

WE PARTICIPATE IN THE ANNUAL EXHIBITION OF MARINE PRODUCERS IN KOREA, BEXCO

The Dibaq Group was at the annual exhibition of marine producers in Korea, BEXCO, one more year bringing the best of its products and R+D+i focusing this year on new species of the future as the Seriola quinquerradiata and new products for RAS culture.

For this, DIBAQ, with the help of the Director of Marine Products Eloy Meseguer and our local partner Otti Rim, gave a conference to demonstrate the potential of our new products in local aquaculture.

ACUACULTURE IN THE AESAN

Global aquaculture production of farmed aquatic animals has been dominated by Asia, with a 89% of the production in the last two decades. Dibaq Aquaculture has set as one of its main objectives the ASEAN area (Association of Southeast Asian Nations), which is responsible for 25% of world production with a total of approximately 30 million tons.

In the ASEAN area, Indonesia is the main producer with 50% of the production of Southeast Asia, with the largest cultivation in sea waters in the region and having shrimp as the most important. The following countries that stand out in production are Vietnam, the Philippines and Thailand.
The main species grown in the region are shrimp, followed by freshwater species such as tilapia, carp and catfish. Although it is true that in recent years high-value crops such as Barramundi (Lates calcalifer) or Asian sea bass and Grouper are being developed, for which Dibaq Aquaculture develops specific formulas.

Currently, the industry in the ASEAN zone confronts important challenges related to the nutritional quality of feed for aquaculture and the digestive health of animals in which Dibaq Aquaculture is constantly working on developing new formulations and investigating the possible inclusion of new ingredients to improve digestibility. and intestinal health, maximizing the efficiency of animal growth and maintaining competitiveness in the market.

In the medium term, growth in the sector is expected, driven by changes in consumer preferences and the demand for increasingly sustainable products. According to the FAO Asia will continue to dominate the aquaculture sector and will be responsible for more than 89% of the increase in production in 2030 and it is expected that most of the fish exports will originate in Asia, which will account for approximately 73 % of additional volumes exported in 2030.

NATIONAL AQUACULTURE CONGRESS IN CADIZ 2022

On November 22, Dibaq Aquaculture attended the XVIII National Aquaculture Congress in Cádiz. The representation of the company was carried out by our colleague Antonio Garcia, commercial veterinary technician from the Department of Nutrition, Health and Animal Welfare. In this Congress there were both representatives of production companies, aquaculture feed, aquaculture material, vaccines, etc., as well as researchers from the sector from Universities and Research Centers, both nationally and internationally.

During the course of the Congress, the different investigations carried out by researchers and companies were presented, always in the field of aquaculture, related to topics such as pathology, nutrition and food, sustainability, new species, etc.

This Congress was very enriching, since in addition to the interesting presentations, in the coffee-breaks all the attendees met to greet each other and chat. As our colleague Antonio García comments, “it is always nice to be able to meet in person with all the colleagues and friends of the sector and catch up on issues that are not only professional, but also personal, and even more so in a place as wonderful as Cádiz is”.

ACUACULTURE, yes o no?

acuiculturasiono

Dibaq was present at the event, which took place on 16 November in the Auditorium of the Provincial Council of Alicante (ADDA), has been focused on the construction of a space for dialogue focused on discussing the possibilities that aquaculture activity has for local economies.

A sector compatible with the usual wealth-generating sectors, such as tourism or fishing, which is a sustainable complement, notable in gender equality and quality for coastal municipalities and empty Spain.

From 9:00 a.m. to 2:00 p.m., different presentations were given by politicians, institutions, fishermen’s guilds and researchers. Among them, such outstanding personalities as the aforementioned Quique Dacosta or the director and producer of documentaries, Céline Cousteau.

DIBAQ AQUACULTURE IN THE EUROPEAN AQUACULTURE CONFERENCE AE22RIM

The European Aquaculture Conference was held in Rimini, Italy, on September 27, 28, 29 and 30 with the title, INNOVATIVE SOLUTIONS IN A CHANGING WORLD.

Traditionally, Dibaq Aquaculture has attended this event as a follow-up to its external communication and commercial strategy.

The trade show was attended by many exhibitors from the sector, from different European origins, as well as from USA and Canada, highlighting, on this occasion, companies that distribute highly technological equipment for aquaculture production, as well as health additives and ingredients.

Regarding the lectures, they were scheduled on different current subjects of interest for the sector: Nutrition, such as presentations on novel ingredients and functional ones; reproduction and broodstock management; fish welfare; precision farming, modeling, and artificial intelligence, among others.

Thanks to this event, we had the opportunity to meet again, with colleagues from the sector, having the chance to exchange impressions and knowledge about the aquaculture activity.

Usually, Dibaq Aquaculture, maintains an intense external communication activity throughout the year, and combines its attendance at conferences and specialized courses in aquaculture with its presence at the most important events of the sector.

To be part of these events, is key in our expanding policy to foreign markets, where we dedicate a high percentage of our global production.

OUR EXPERIENCE AS MANUFACTURERS

Our experience as manufacturers of aquaculture feeds allows us to achieve healthy, digestible products with a high conversion rate, made using cutting-edge technology, capable of maintaining their structure in the water, meeting the requirements of floating or sinking, and highly resistant to transport. and storage.

Our manufacturing process based on twin-screw extrusion technology allows the transformation of solid materials by mixing, heating, cooking, gelatinizing and molding until a very high-quality product is obtained for a wide variety of aquatic species.

The know-how accumulated over the years is the cornerstone of our internal training system where all the knowledge is transmitted to the people we incorporate into our project -DIBAQ LEARN.

An experienced team of technicians specialized in manufacturing is responsible for transmitting the knowledge to the people who join the training process. During this stage, the trainer accompanies the student throughout the learning period, explaining all the variables of the process through detailed controls established at different points of the manufacturing line, paying special attention to the optimization of energy costs, closely related to know-how. , experience and skill of our staff.

We use sustainability criteria as a reference in our production processes, both in the design of facilities and in the operation of processes. The energy efficiency we have been working on for years allows us to achieve the double objective of optimizing production costs (an aspect that is particularly relevant currently due to rising energy prices) and respect for the environment. In this last chapter we have implemented policies and certifications for the minimization of process impacts on atmospheric emissions, effluents, and waste.

NUTRITION AND HEALTH OF BARRAMUNDI (LATES CALCARIFER)

At Dibaq Aquaculture we have been formulating quality products for the different species of aquaculture fish from around the world for more than 30 years. Among these species is the Asian sea bass (Lates calcarifer), better known as barramundi, which is produced in the area of Southeast Asia. This carnivorous fish is a species that adapts very well to captive production conditions and obtains a great yield with quality extruded feed, growing rapidly and reaching commercial size (350 g – 3 kg) between six months and two years. 

In order to achieve an effective extruded feed and satisfy our customers in Asia, at Dibaq Aquaculture we focus deeply on fully understanding the nutritional needs and requirements of each species at the different stages of production, in this case the barramundi.

Regarding protein levels, due to the carnivorous nature of this species, it has a relatively high protein requirement. Protein requirements are typically above 45%. If we talk about fat levels, we have verified after various trials and confirmed with our clients, that the best results in terms of performance have been seen in fat profiles between 10% and 18%, with the levels of EPA and DHA above 1,5%.
With reference to micronutrients, vitamins such as vitamin C, are very important for proper growth and avoid deformities at an early age. Inclusion of a level of 500 to 700 mg/kg of diet favored normal growth. As for the rest of the vitamins, for example pantothenic acid, inositol, vitamin E and pyridoxine, they are also necessary for normal growth. Among the most important minerals, phosphorus and zinc must reach correct levels as well.

Within our range of products for this species, we have the best raw materials, of excellent quality, to be able to reach and exceed the necessary levels and profiles of macronutrients and micronutrients to achieve a complete feed and with it a rapid and correct development of the barramundi.

However, we cannot forget that, in intensive production, it is very important to know the possible pathologies that can affect each species. Knowing the pathogens, the symptoms, ways of transmission of the pathogen, etc., is necessary to achieve a rapid and effective diagnosis in the event that the disease is established. However, it is also necessary to prevent the appearance of any disease through biosecurity measures, management, etc., and thus avoid mortality.

MAIN PARASITES OF BARRAMUNDI

The predominant parasites of this species are Protozoa, Mixozoa and Monogenea, ectoparasites of skin and gills.

The most abundant are the Monogeneans, external pathogens such as Pseudorhabdosynochus epinepheli, Pseudorhabdosynochus lantauensis, Benedenia epinepheli and Neobenedenia melleni, the latter one of the most common in marine farms. They are large parasites that are provided with hooks that can cause significant damage to the host during their feeding activity in cases with a high prevalence. Affected fish quickly become inappetent, lethargic, with anemic and swollen gills, and develop exophthalmos, erosions of the skin and body.

As for protozoa, ectoparasites as well, which can cause significant illness and mortality in RAS systems with tanks or ponds that, with a high density, will have the ideal conditions for their appearance. Heavy infestations of protozoan parasites cause irritation and tissue responses such as hyperplasia, edema, increased mucus, hydropic degeneration, and necrosis, all in both the skin and gills. Among these parasites we find Cryptocaryon irritans, Trichodina spp. and Trypanosoma spp. These parasites usually proliferate with oxigen concentrations below 4 ppm, densities above 80kg/m3, dirty water, stressful situations…

Within the internal parasites we also find Coccidiosis due to Eimeria spp., whose infestation is usually associated with serious pathology and significant mortality in small barramundis.

At Dibaq Aquaculture, we once again mention the importance of proper nutrition and health of aquaculture species, factors that the Animal Nutrition, Health and Welfare Department covers throughout our wide range of products, since we know the species to which our high quality products are aimed. In addition to having services such as pathology, diagnosis and treatment of diseases, advice on the production of the installation and training in aquaculture welfare, health and biosafety for our clients.

A VALUABLE RAW MATERIAL

Fish intended for direct human consumption is often processed in a way that makes the eating experience easier and faster for the consumer. That processing gives rise to by-products such as heads, entrails, bones, skins, tails, etc.

All these by-products are considered a valuable raw material from which fishmeal and fish oil can be produced and can come from wild-caught fish or aquaculture processing.

In terms of reducing such by-products into valuable marine ingredients, some fishing vessels are even equipped to retain or process by-products on board, and shore-based facilities have developed fast and efficient collection methods to ensure optimum quality in their manufactured meals and oils.

CAPTURES

As reflected in the latest report The State of World Fisheries and Aquaculture (SOFIA, hereinafter), the FAO estimates that the total world capture fisheries are close to 100 million tons per year. These catch levels have been relatively stable since the late 1980s, primarily due to growing awareness of the need for sustainable fishing. According to the figures presented in the SOFIA report, the percentage of the capture fisheries that was used for direct human consumption in 2018 was approximately 75 million tonnes and about 15 million tonnes of the remaining capture fish was used as feedstock to produce marine ingredients. Additionally to capture fisheries, the aquaculture industry is responsible for an impressive growth in the supply of fish for human consumption, producing around 82 million tonnes of fish in 2018.

When we analyse fishmeal and fish oil separately, we find that the world production of fishmeal from by-products represents 29.8% while the production of fish oil from by-products represents 51% of the total production of fish oil.

Although these numbers tell a promising story, there is still a large percentage of the by-product of fish for human consumption that is wasted instead of being converted into high-value products that contribute to the supply of nutrient-rich marine food.

In addition to this, global fish production is expected to continue to grow, mainly due to growth in aquaculture fish production. It goes without saying that the increase in aquaculture production will also guarantee a growing potential supply of raw material to produce these marine ingredients.

It is essential for our sustainable livelihood to encourage as much as possible the continuous development and optimization of the collection and processing of this invaluable source of raw material.

SEAFOOD BARCELONA 2022

SEAFOOD BARCELONA 2022

Dibaq Aquaculture was present at SEAFOOD Barcelona 2022, the most important fair in the sector worldwide. There have been two years without a celebration, and this has translated into spectacular results, with more than 1,600 exhibitors from 80 different countries, who occupied the more than 45,000m2 of the Fira de Barcelona.

Even with the geopolitical situation in Russia and the health situation in China, more than 30,000 people have passed through the Fair and our General Director, José Luis Tejedor, had the opportunity to attend and witness the new trends that were presented in the sector, in addition to taking advantage to visit, talk and continue strengthening our commercial ties in the 5 continents. An excellent opportunity that already has a date for next year, from April 25 to 27, 2023, in the same city, and in the same place.

Dibaq Aquaculture participates in Inmuno&Algae

Last April, Dibaq Aquaculture was invited to participate in the final Immuno&Algae Conference organized by Ctaqua (Technological Center for Aquaculture) in Puerto de Santa María (Cádiz).

Elvira Alcalde, head of the animal nutrition, health and welfare department at Dibaq Aquaculture, participated in this interesting event, within Session 2: The challenge of functional foods in aquaculture, with the presentation, “Functional foods as a sectoral challenge.” , a presentation with which he shared the extensive experience that the Group has in the development and application of this type of food and in which he highlighted the improvements that are achieved from the point of view of the production and health of the fish, with the use of the products that are part of its line of functional foods, Dibaq Aquasafe.

WE HELD AN IN-HOUSE TECHNICAL AND STRATEGIC WORKSHOP

Grupo Tejedor Lázaro, in its fervent search for excellence in the design and cooking of pet food and aquaculture fish feed, has held an internal technical and strategic workshop where new trends, forms and flavours in the animal nutrition of the future. A total of 14 international experts in engineering, extrusion and nutrition from the Group have tested the behaviour of the kitchens and new ingredients that are part of the recipes and assortments that we offer in more than 70 countries on 4 continents.

The use of new sources of sustainable proteins, respectful with the environment and seeking the best results and animals; the search for new textures, densities, flavours, aromas and behaviours in the mouth; or the maximization of the inclusion of certain ingredients in recipes were some of the topics worked on, which will soon form part of the assortment of products that our animals will be able to enjoy all over the world.

SUSTAINABLE TRENDS IN AQUACULTURE NUTRITION

The world’s population will approach 10 billion by 2050 according to the FAO. As the population grows, the demand for food and more specifically for protein sources increases accordingly.

Therefore, the demand for aquafeed (as a source of protein and essential fatty acids) is also increasing.

Global aquaculture production reached 120 million tonnes in 2019(FAO), 3.7% more than the previous year and again surpassed extractive fisheries, this time by more than 26 million tonnes.

The sustainability of aquaculture is based on efficiency in the use of available sources to supply this unstoppable increase in population with nutritious and accessible protein.

In recent years, aquaculture recipes have evolved to incorporate a large number of raw materials that provide us with the nutrients necessary for the development of the farmed species in question.

However, even today, in a significant part of aquaculture diets, the use of both fishmeal and fish oil is still significant, especially in diets intended to feed carnivorous species, as the characteristics of these raw materials, high protein content, optimal amino acid profile, high content of long-chain n-3 polyunsaturated fatty acids, source of phospholipids and cholesterol, as well as minerals and vitamins, cover the needs of this type of aquaculture species.
However, modern aquafeeds are sophisticated and include a combination of ingredients designed to facilitate intensive and efficient production. They incorporate cereals, legumes, bran, starches, flours and oilseed concentrates, processed animal proteins, marine proteins, marine and vegetable oils, enzymes, vitamin and mineral premixes, pigments and additives, thus reducing dependence on traditional raw materials.

Current trends towards a more sustainable horizon include, for example, the use of microalgae and macroalgae as alternative sources of oil. Although their use is still limited, formulations with some inclusion are available, helping to reduce dependence on fish oil.
The number of companies starting to produce oil from microalgae is increasing and their production technology is improving, so we expect availability and competitive prices in the medium term.

On the other hand, and although there are economic, regulatory, social and environmental challenges today, the use of bacteria, yeasts and insects in aquaculture diets will also increase in the near future.

At Dibaq Aquaculture we are very clear that modern aquafeeds must also be affordable products and provide healthy solutions and in this sense, there are different types of functional additives that improve the welfare of fish, boosting their immune response and reducing stress.

Different bacterial, fungal and viral pathogens are responsible for high mortality rates. In aquaculture, this is a limiting factor and has a major impact on the industry. There is therefore a need to control the effects of these pathogens without resorting to chemotherapeutics. Considering alternative approaches and with the clear objective of reducing the use of antibiotics, different immunostimulants are used, which enhance immune responses together with their level of gene expression through different signalling pathways.

When we manage to act positively on the immune system of the fish, the effect on the production parameters is direct, as they are prepared to fight infections and, therefore, we avoid their negative effect on growth and feed utilisation.

The global market for aquaculture feed additives is experiencing a rebound, in Europe alone, it is expected to reach 285 million dollars (CAGR of 4.8%) by 2026, according to GM insights.

Among the products that help us to improve fish immunity and that we can include in our recipes are the so-called prebiotics and probiotics.

Both are products derived from yeasts and beneficial bacteria that have been successfully tested in many animal species with the aim of improving the physical barriers in the gut and the immune system, helping to promote better growth in the animal.

In aquaculture, the incorporation of probiotics, although their use in Europe is limited to a single bacterial species, is a viable tool that reduces or eliminates the incidence of pathogenic micro-organisms, and constitutes, as I said, an alternative to chemotherapeutic agents in the prevention of infectious diseases. On the other hand, they also offer nutritional benefits, providing enzymes, vitamins and micronutrients, thus contributing to reducing mortality and maintaining the homeostasis of the individual.

Prebiotics also have the potential to increase the efficiency and sustainability of aquaculture production. They act as nutrients for the gut microbiota. Today there are different products used with prebiotic effect, some of the most proven in aquaculture are mannan-oligosaccharides (MOS), complex carbohydrate molecules from the wall of the yeast Saccharomyces cerevisiae, which prevent the adhesion of bacterial pathogens, thus hindering the colonisation and infective process of pathogens.

At Dibaq Aquaculture, we believe that, as is happening with other feeds, aquafeeds will become increasingly specific, sustainable, palatable, digestible and nutritious. In addition, automated feeding systems, new RAS (recirculation system) productions, whose technology requires a special feed in terms of composition as not all feeds are compatible with this production system, will improve the performance of species and reduce feed wastage.

As we have been doing at Dibaq Aquaculture in recent years, aquaculture feed nutrition must continue to look beyond traditional raw materials, seeking complementarity with them through technological and nutritional strategies.

We know that aquaculture species have needs in terms of nutrients, not ingredients, and although we have already come a long way, we must continue to innovate in this direction.

How can the end of the winter season and the beginning of rising
temperatures affect sea bream?

Sea bream is a aquaculture production specie that withstands cold temperatures more delicately than sea bass, so during the winter it is important to maintain adequate feeding strategies for this species in areas where the water drops below 14ºC during the winter season. During this time of the year, the optimal production conditions to avoid mortality as much as possible are those that follow an extensive model. From the Nutrition, Health and Welfare Department of Dibaq Aquaculture we advise against intensive production conditions for sea bream between 13-17 ºC in order to avoid metabolic and physiological pressure that sea bream cannot withstand at these temperatures.

In addition, another critical moment can also be the end of winter and the rise in temperatures, a moment to which special attention must be done.

The well-known Winter Disease, a metabolic syndrome of multifactorial origin that affects marine cages production farms, which we have already discussed, may have two phases or processes in this species.

In the first phase of the disease, which can be established from December to March, a low chronic mortality can be observed, and in the second phase, which occurs from April to May, is where a subacute mortality can be seen that can reach 20 % of the total in less than a month. One of the possible causes for this second stage of the Winter Disease to have a higher mortality in a shorter period of time is that the fish have been for several months at low temperatures and their immune system has been “lethargic” or with a lower activity than at other times of the year at high temperatures, therefore immunity can be low. If we add this to the physiological and metabolic imbalances that low temperatures can cause in this species, what we obtain is that the sea bream becomes more predisposed to infection by Pseudomonas anguilliseptica, a bacterial pathogen that is more active at this time of the year.

Therefore, in this second phase of the disease, we obtain the metabolic problems associated with low temperatures and a possible infection by Pseudomonas anguilliseptica, which results in this rapid increase in mortality.

For all these reasons, it is important to have feeding strategies in the farm based on seasonal temperature and light, fish size, farm conditions, etc. From the Nutrition, Health and Welfare Department we help our clients to follow the best feeding strategies throughout the year, not only for sea bream, but for all current production species. For this, we recommend the products that we consider optimal for each moment of the year, taking into account the species, the size of the fish, the energy of each product and including our quality brand of Dibaq AquaSafe functional and health products for the improvement, support and support of immunity in specific moments of the production stages, in order to avoid, as far as possible, increases in the mortality of the species. For Dibaq Aquaculture, nutrition and health follow the same way in aquaculture.

For example, for sea bream in the stage of finishing winter and entering summer, it must be taken into account that it is a phase of acclimatization of the fish to the increase in temperature and again to the progressive increase in the daily feeding rate. It is important to carry out immunostimulation/immunomodulation for 2/3 weeks in this stage prior to the beginning of summer, since the fish have been during the previous stage with their immune system at minimum. Therefore, it is a good action “reactivate” the immune system after winter. This is one of the many recommendations that we offer to each client in a personalized way according to their farm and production method, in addition to our 360º Service, where we continuously accompany the client in all the production cycle.

DIBAQ APARTMENT 360º IN THE WORLD

Dibaq is unfolding all its potential and history of more than 35 years in Aquaculture in the world.

When the first generation of the Tejedor Lázaro family founded the Dibaq company more than 70 years ago, they did not imagine that their products would be sold in markets as far away as Korea, Sri Lanka or Peru.

Why a Spanish family business can reach these markets is both very simple and very difficult: dedication to the customer.

Dibaq’s 360º service means that our products are manufactured in Spain but the ideas come from all corners of the aquaculture world. When our clients need a special product, our 360º department is there. When our clients have a problem on the farm, our 360º department is there. This department is made up of specialists in nutrition, veterinary medicine, chemistry, engineering, or biology, among others.

The challenges can be from particular needs in the feed to improve the quality of the water, looking for special buoyancies in the feed, special profiles of the feed to enter some world markets, solving engineering problems in their RAS facilities or cages… On many occasions, We adapt the extensive knowledge that our clients have regarding the species they work to develop ad-hoc feeds for their farm.

Other times it is a recurring pathology on the farm and through our department and working side by side with our client we manage to eradicate or alleviate that disease.

Thus, our customers in the US, Asia, Africa or America work together with us as true technological partners, promoting and giving birth to new products for the new challenges of aquaculture in the 21st century.
Dibaq currently exports more than 80% of its products, for more than 25 species in tanks, cages, RAS or ponds.
