Evaluación de péptidos bioactivos marinos en el cultivo de engorda del camarón blanco l. vannamei (boone, 1931) en cautiverio.

Abstract

Cultured production of L. vannamei represents 70% of world shrimp production. Aquaculture crops have intensified in number of organisms per unit area and volume, making the use of formulated feed indispensable for animal feeding. It is known that the shrimp production field generates approximately 60% of its production cost. Nowadays, the raw material obtained in aquaculture production, whose fish and shrimp by-products are constituting a problem of environmental pollution due to lack of utilization, it is considered that one of the most viable methods to take advantage of these resources are bioactive peptides (hydrolyzed) as feed additives for aquatic organisms. The objective of the study was to evaluate the effect of fish hydrolyzate in the balanced feed on the productive performance of shrimp in captivity. Eight 1 m² cages were used, seeding 15 shrimp with average initial weights of 15.6 g. The hydrolyzate used was of fish origin. The hydrolyzate used was of commercial origin. Two treatments were carried out: a) feeding the shrimp with the balanced feed plus fish hydrolysate, b) balanced feed only (control). Each treatment was managed with four replicates. The results obtained show that in terms of weight and survival there were no significant differences (P>0.05), the shrimp fed with the balanced plus hydrolyzed treatment presented a greater numerical difference in terms of weight and survival with an overall average of 20.76 g and 71.6% as opposed to the control group that presented an overall average weight and survival of 19.68 g and 68.3%. Likewise, the FCA was more efficient in the hydrolyzed treatment with a 3.35 on the contrary to the balanced treatment, which was less efficient with a 4.79. In production costs, there is a higher expense in the treatment with hydrolyzate added, however, the days of cultivation are reduced and a higher production yield is obtained with the treatment with hydrolyzate. It is concluded that the use of hydrolyzates in aquaculture is beneficial, since it generates favorable results in the productive yields of shrimp farming.
