| Abstract |
Brine shrimp is an essential food for marine shrimp larviculture due to their nutritional composition, but the effects of the use of a conserved product is not yet available in the literature. In view this, this study evaluated the use of fresh brine shrimp (F-BS) and conserved (C-BS) of Artemia sp. on the larval performance of Penaeus vannamei. Two trials, i.e., the first on a laboratorial scale (experimental units of 10 L) with four independent replications, and the second on a commercial (large-scale ponds of 25 m3) in triplicate, were conducted to assess the effects of F-BS and C-BS on water quality, bacterial presence, and zootechnical performance of P. vannamei. The data were submitted to normality and homoscedasticity tests, when these assumptions were met, Student's t test was used. To data non-parametric was used Mann-Whitney U test. For all analyses, a significance level of 5 %. Water quality parameters were within the recommended levels for the specie and did not differ between treatments. Bacterial colonies in the water were higher when using F-BS compared to C-BS in both trials; in the shrimp, no significant different were found between the diets, but the number of bacterial colonies were higher in commercial scale trial when compared to laboratorial scale one. For water quality, bacterial concentration, larval development indexes and zootechnical performance, no significant different were observed between the brine shrimp forms at two trials. In conclusion, the use of C-BS promotes a similar performance in comparison to F-BS in the larval cultivation of P. vannamei. |
