Growth of litopenaeus vannamei shrimp in juvenile stage in two feeding systems: 1.- commercial diet combined with molasses and 2.- commercial diet mixed with semolina and molasses

Abstract

In shrimp farming, commercial feed represents 60% of the production cost, with this research we tried to obtain an alternative to reduce production costs with the application of a nutritional supplement based on a diet ration of 80% commercial feed and 20% commercial feed. combination of semolina and molasses. This research aims to determine the growth of Litopenaeus vannamei shrimp in the juvenile stage in two commercial and experimental feeding systems. This study was carried out at the facilities of the Marine and Aquaculture Research Laboratory (LIMA) of UNAN–LEON. In the experiment, 6 plastic containers were used, we planted 12 organisms (in one repetition) applying the commercial diet and in the other battery with the same number of organisms the experimental diet was given. With respect to physical-chemical factors, temperature and pH remained at their optimal values, growth in the experimental system was 9.33 g and in the commercial system 7.45 g, obtaining a value of p>0.05 , which indicates that there is a significant difference between both treatments, with a survival of 100% in both systems. The productive yield in the experimental system was 4,600 Lb/ha and the commercial system was 3,600 Lb/ha.
