| Fish meal (FM) has long been considered an essential ingredient for the formulation of shrimp feeds. Until recently, 12%FM was considered a minimum amount, below which weight gain would become reduced due to a reduction in feed intake. In order to test this perceived minimum value, an experiment was conducted on a long-term basis with 4 replicates. Four practical isonitrogenous and isoenergetic diets were formulated for Litopenaeus vannamei juveniles. Survival, weight gain, feed conversion ratio (FCR) and protein efficiency ratio were determined for 0, 6, 10 and 15% FM diets and a reference diet. Shrimp survival ranged from 84 to 86.5%. Shrimp fed a diet with 0% FM showed lower average weight and SGR compared to the other treatments (P<0.05). FCR of... |

| The advantages of FLOC over clear water (CW) in rearing juvenile L. vannamei and its effects on Vibrio communities were evaluated. Survival rate in FLOC and clear water were recorded and a probiotic was tested under both conditions. Daily growth rate (DGR) was higher in FLOC (p < 0.05) than in CW. Survival in each system increased significantly when a probiotic was included in the diet (p < 0.05). The Vibrionaceae community from the hepatopancreas (HP) and the culture medium did not differ between the two culture media. Nevertheless, a novel group of Vibrio strains was found to be unique to FLOC. No high level of lesions was observed in shrimp tissues from the FLOC + probiotic treatment; it suggests that the probiotic contributed to homeostasis and... |
