ABSTRACT: The present study evaluated the growth performance, survival, feed conversion ratio, intestinal morphometry, and final yield of yellow tail tetra Astyanax bimaculatus after dietary supplementation with probiotic Lactobacillus sp. at a concentration ≥ 1.0 × 107 CFU g-1. For this purpose, 480 fish (0.25 ± 0.03 g) were randomly distributed into 16 experimental units 20 L (30 per unit) divided two-factor design (2×2). subjected to four treatments for 90 days: low stocking density (0.75...
This work aimed to evaluate the probiotic Lactobacillus spp. in microbiota of Astyanax bimaculatus reared a water recirculation system. The experiment was randomized, using 800 postlarvae distributed into eight polyethylene containers, separated two treatments, quadruplicate: supplementation with (Probiotic) and no (Control). After 90 days culture, 13 fish per container were anaesthetized. Three these underwent microbiological evaluation, haematological analyses carried out on five....
ABSTRACT The objective of this study was to evaluate the effects dietary supplementation with different doses Curcuma longa hydrolate on hematological, immunological and zootechnical parameters Nile tilapia cultivated in a recirculation system (RAS). (Oreochromis niloticus) were used, distributed 16 polyethylene boxes, divided into four treatments: 0.0%; 2.5%; 7.5% 10.0% hydrolate, quadruplicate. After 45 days treatment, fish per experimental unit anesthetized remove blood aliquot for...

ABSTRACT This study aimed to isolate native lactic acid bacteria of yellow tail lambari (Astyanax bimaculatus) and evaluate their effect on host microbiota gut morphology, as well survival after experimental challenge. The isolated bacterial strains were evaluated for inhibition against pathogenic in vitro, the strain with highest inhibitory ability was molecularly identified Lactobacillus spp. For vivo testing, eighty fish distributed ten tanks equipped a recirculation system. units divided...
ABSTRACT This study aimed to compare the body indexes and hematological characteristics between Astyanax bimaculatus males females. Four hundred fish were randomly distributed into four polyethylene tanks (100 fish/unit) in a recirculation system fed times day (3% of biomass). After 90 days, ten (five ♀ five ♂) removed perform blood tests measure weight, height, total length, height/length ratio, condition factor index determination: vicerosomatic (VSI), hepatosomatic (HSI), gonadosomatic...
