Aquaculture has historically relied on fishmeal as the main protein source in fish feed. However, the sustainability of this practice has been questioned due to overexploitation of marine resources and fluctuating availability and cost of fishmeal. In response, companies such as Dibaq Aquaculture have intensified research and adoption of alternative proteins to reduce this dependence and promote more sustainable practices.

Microalgae: a rich source of nutrients
 
Dibaq Aquaculture has increased the use of microalgae in its formulations. These offer a high protein content of excellent quality and an outstanding profile of essential polyunsaturated fatty acids, such as omega-3 and omega-6, including EPA and DHA. The incorporation of microalgae not only improves the nutritional value of the feed, but also contributes to sustainability as it is a renewable source with low environmental impact.
 
Yeast and unicellular bacteria proteins

Another strategy adopted by Dibaq is the inclusion of proteins derived from yeast and unicellular bacteria. These alternative protein sources can replace a significant percentage of marine proteins in aquaculture diets. In addition to their high protein content, these sources offer advantages in terms of sustainability and availability, reducing pressure on traditional fisheries.
 
Insect meal: an emerging option
 
Insect meal, especially that obtained from the black soldier fly (Hermetia illucens), is emerging as a promising alternative. This ingredient offers a high level of protein and an amino acid profile suitable for meeting the nutritional needs of various fish species. Dibaq has explored this option, considering its potential to reduce dependence on fishmeal and improve the sustainability of aquaculture production.

Commitment to sustainability

In addition to incorporating alternative ingredients, Dibaq Aquaculture is committed to sustainability through the use of fishmeal and fish oils from responsible fisheries. This practice, together with the inclusion of alternative proteins, has enabled the company to achieve a historically low FIFO (Fish In Fish Out) index, positioning the producer as a potential protein generator for the world’s population.
