Abstract: | The objective of this work was to evaluate different diets in the development of L. vannamei post-larvae in intensive nurseries. For this experiment were used 264,000 PL10 with initial weight and length of 11.0 mg and 9.78 mm, respectively, distributed in 12 nurseries of 1,000 L, cultured during 10 days. Four treatments were tested (control - CR40-ART, CR42:48-ART, CR42:48:52 and ART) which were composed of 4 artificial and 1 natural diet, with 3 repetitions, distributed in an entirely randomized delineation. Post-larvae were fed in the proportion of 15% of total biomass. The best survival rates were verified in the treatments CR42:48:52, CR42:48-ART, ART and CR40-ART; with 91.3; 90.5; 81.8 and 70.9% (p > 0.05), respectively. The best development occurred in the shrimp of CR42:48:52 treatments, confirmed by the Tukey Test (p < 0.05), to final length and weight, weight and length gain, food conversion and increments, in comparison to individuals from ART treatments. In regards to biomass gain and final biomass, the CR42:48:52 treatment differed from CR40-ART and ART (p < 0.05) treatments. We concluded that use of different products with high nutritional value gave post-larvae high zootechnical indices, producing shrimp of excellent quality for stocking ponds. |
