Feed formulation for blackspot seabream and Senegalese sole

Objectives and main results

The project aims at the consumption of specific foods and linguistic and can contain the nutritional needs of each species and at the same time. Nowadays, the tiny fish farms that belong to the plant culture have turned to the sparrow and vascular diets, which manifest their hypotheses of life to new species. As the new formulas tested for control have already been performed, growth is good for fish and a per-visceral fat deposition. In the case of the given language, the lysine requirements, being an important step for a diet correction with protein sources. Finally, and to the extent that protein distribution may have been a consequence of growth, a study of feed behavior with customers using automatic feeders and a request becomes critical. In order to use these self-feeding systems, the results, although with sole, are more complicated. With the proposed objectives it is hoped to arrive at the diets that allow a good growth of the animals and certain conditions of life by this one and with more of a click.
