Stocking density at rearing phase for white shrimp farmed in a biofloc system

Show other versions (1)

The objective of this work was to determine the optimal stocking density for Pacific white shrimp farming, in biofloc culture system (BFT) without water exchange. Two completely randomized experiments were carried out, with three replicates for each treatment. In the first experiment, juveniles with 1.23±0.09 g initial mean weight were reared at the stocking densities of 833, 1,250, 1,667, 2,083, and 2,500 shrimp per m3. In the second experiment, the initial mean weight was 6.32 ± 0,7 g, and the densities were 566, 833, 1,111, 1,388, and 1,667 shrimps per m3. The best productivity results, with the means 9.92 and 10.77 kg m-3, were obtained at 1,667 and 1,111 shrimp per m3, respectively, in the first and second experiments. Increasing stocking density affects growth and survival of white shrimp farmed in biofloc system.

O objetivo deste trabalho foi determinar a densidade de estocagem ideal para o cultivo de camarão‑branco, em sistema de biofloco sem renovação de água. Foram realizados dois experimentos inteiramente casualizados, com três repetições para cada tratamento. No primeiro, juvenis de camarão‑branco, com peso médio inicial de 1,23±0,09 g, foram cultivados a densidades de estocagem de 833, 1.250, 1.667, 2.083 e 2.500 camarões por m3. No segundo experimento, o peso médio inicial foi de 6,32±0,7 g, e as densidades foram de 566, 833, 1.111, 1.388 e 1.667 camarões por m3. Os melhores resultados de produtividade, com médias de 9,92 e 10,77 kg m-3, foram obtidos com 1.667 e 1.111 camarões por m3, respectivamente, no primeiro e segundo experimentos. O aumento da densidade de estocagem afeta o crescimento e a sobrevivência do camarão‑branco em sistema de biofloco.
