USE OF FERMENTED VEGETABLES IN AQUACULTURE

Currently there is a tendency to intensify production processes and aquaculture is no exception. However, sometimes there are various structural limitations that prevent the increase in production units, so there is a tendency to modernize the cultivation processes while maintaining the same production units in order to achieve greater production.

 

This leads to demanding the maximum from the cultivation systems, such as, for example, sometimes reaching the limits of biomass loads for each of the systems, a fact that in turn affects the increase in water quality parameters that they are not adequate, leading to the detriment, the increase of the load per m3 and therefore the friction of animals against each other, increasing oxygen consumption, stress in animals and the most frequent appearance of pathologies. As a measure to solve these drawbacks, oxygenation systems tend to be improved or increased, but this would only be one of the steps to be taken in order to obtain good production volumes.

 

At Dibaq Aquaculture we are aware of the importance of high-quality food for our fish and shrimp. For us, it is an objective to find a well-balanced food for each of the species and in each of its productive stages, which generates the minimum waste and meets its nutritional requirements, also giving an extra contribution of organic vitamins and minerals to improve all the physiological processes and that the fish are prepared for any adversity.

 

In addition, it is very important that the raw materials that make up the products we offer our customers meet sustainability standards. This is where vegetable-based meals come in as partial substitutes for fish meals that are becoming increasingly scarce and their prices are always rising, thus contributing to the sustainability of our planet without creating so much dependence on the increasingly limited raw materials of fishing origin.

 

Within the group of plant-based flours, one of the most important is soybean, due to its high protein and amino acid content, but other factors must be considered with this raw material, for example, the amount of anti-nutritional factors that it has, among which oligosaccharides, saponins, etc. can be mentioned. On the other hand, it also contains phytic acid that decreases the bioavailability of essential minerals such as iron, zinc and calcium, essential in fish. Faced with these problems, there is the alternative of using fermented soybeans, since the fermentation process largely eliminates anti-nutritional substances. In turn, the fermentative process generates a series of short-chain organic acids such as butyric, valeric, acetic or formic acid.

 

These organic acids can help create certain inhibition halos against some pathogenic strains, such as Vibrio spp., which helps us to strengthen the immune system of our fish. As a result of our constant innovation and improvement work, at Dibaq Aquaculture R+D+I test are being carried out with the use of this ferment and a combination of other natural additives to seek an improvement in the performance and immune system of fish and farmed shrimp, in order to help the fish farmer to improve his productivity as much as possible.
