Cuban researchers develop metabolic modifiers improving productive efficiency in aquaculture

Cuban researchers have developed metabolic modifiers that stimulate the growth and immune system of fish, crustaceans and bivalves, among other marine organisms, Cuban state media reported.
It is a series of innovative products grouped under the name Acuabios, created by specialists from the Agricultural Research Directorate of the Centre for Genetic Engineering and Biotechnology (CIGB).
As explained to the official newspaper Granma, science doctor Mario Pablo Estrada García pointed out: "the favorable results achieved experimentally and in field trials conducted in Cuba and other countries, mainly in Chile and Peru, allow us to predict the success and extensive use in the world aquaculture industry, in particular of the last version called Acuabio V".
The scientist noted that among the proven positive effects of its use what stands out, for example, is the increase in growth rate, resistance to pathogens, survival and larval development in fish such as tilapia and salmon. Likewise, it was observed that this product stimulates growth, larval survival and weight gain in several shrimp species, and the significant increase in the survival of initial larvae in the Peruvian scallop (Argopecten purpuratus).

Specific studies carried out in the south of Chile with salmon showed that this nutritional complement gives treated larvae an early development of their innate immunity and, therefore, a high resistance to microorganisms that cause diseases, including those caused by flatubacteria. It also favours a greater homogeneity in the sizes of the specimens.
Asked about its use in Cuba, the researcher said that it has already been tested in domestic shrimp farming, while coordinating its use in the production process of shrimp larvae.
"The use of biotechnology makes it possible to significantly increase the yields in aquaculture and reduce the implementation of chemicals and antibiotics in this branch" stressed Dr. Estrada. "By developing the Acuabios supplements with its own technology, the country not only has a new and hopeful source of income in foreign currency, it also opens a window in the strategic purpose of moving towards sustainability in food production," he concluded.

The nutritional supplement Acuabio V won the National Prize of the Academy of Sciences of Cuba 2017, under the heading of Agricultural Sciences and Fisheries.
