“…O sistema de microcosmo manteve as variáveis físico-químicas basicamente idênticas para todos os tratamentos e dentro da faixa recomendada para o cultivo da espécie (Van Wyk & Scarpa, 1999;Lin & Chen, 2001Decamp et al, 2007;Avnimelech, 2009;Furtado et al, 2011;Gaona et al, 2011;Maicá et al, 2012). Portanto o sistema de recirculação, baseado no esquema proposto por Moss & Moss (2004), mostrou-se eficiente para separar os efeitos do estresse populacional e da degradação da qualidade da água, sobre o desempenho dos camarões, em razão do aumento populacional.…”

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.

ABSTRACT. The objective of this study was to evaluate the effect of stocking densities on productive performance of the freshwater prawn Macrobrachium rosenbergii in biofloc system. Experimental tanks (microcosms) with 0.20 m² area were used as experimental units. The tanks were connected to two 300 L matrix tanks (macrocosm) with biofloc technology, used as recirculating units. M. rosenbergii juveniles, with an initial weight of 0.315 ± 0.06 g and initial length of 33.34 ± 2.26 mm, was randomly distributed in the experimental tanks at different stocking densities (50, 100, 150, 200 and 250 ind m -²) and reared during 60 days. The total biomass at the end of the experiment was significant higher (P < 0.05) with the use of higher stocking density (250 ind m -2 ). However, prawns stocked at the density of 50 m -2 showed significant higher (P < 0.05) survival (73%) and significantly lower values (P < 0.05) for feed conversion rate (1.28). The different stocking densities evaluated did not affect the weight and length of prawns. The recommended density for growing M. rosenbergii in the biofloc system is 50 ind m -2 .

“…The nitrate and phosphate concentrations were analyzed weekly and also followed the methodology proposed by Strickland & Parsons (1972). Alkalinity analyzes were also performed weekly, according to the American Public Health Association (1989) and adjustments with calcium hydroxide were done following the methodology described by Furtado et al (2011).…”

ABSTRACT. This study evaluates the effects of the previous addition of sodium nitrite (NaNO2) and biofilm in a Litopenaeus vannamei biofloc culture. Five treatments were tested in 180 L -tanks: NaNO2 (-20) addition of NaNO2 for 20 days before stocking and without artificial substrates; NaNO2+B (-20) addition of NaNO2 for 20 days before stocking, with 150% additional artificial substrates; NaNO2 (Stocking) addition of NaNO2 at stocking and no artificial substrates; NaNO2 +B (Stocking) addition of NaNO2 at stocking, with 150% additional artificial substrates and; Control, without NaNO2 addition and without artificial substrates. The study was carried out in two phases: shrimps (0.21 ± 0.08 g) were stocked at a density of 400 ind m ) for 18 more days (grow-out). The turbidity and seattleable solids were higher in treatments without artificial substrates, independently of the addition of NaNO2. The ammonia and nitrite were lower in control, and the nitrate concentrations were higher in treatments with addition of NaNO2 without biofilm. At the end of the nursery, the survival was lower in treatment NaNO2 (-20), and at the end of grow-out the final biomasses were higher in treatments with addition of NaNO2 at the stocking day. In conclusion, the use of a dose of NaNO2 at the stocking day could increase the nitrite-oxidizing bacteria, and the biofilm may contribute to the reduction in suspended particles in water, enhancing shrimp production in biofloc technology system.

Se evaluó los efectos de la adición previa de nitrito de sodio (NaNO2) y biofilm al cultivo de Litopenaeus vannamei en sistema biofloc. Se analizaron cinco tratamientos en estanques de 180 L: NaNO2 (-20) adición de NaNO2 durante 20 días antes de la siembra y sin sustratos artificiales; NaNO2+B (-20) adición de NaNO2 durante 20 días antes de la siembra y con 150% de adición de sustratos artificiales; NaNO2 (Stocking) adición de NaNO2 en la siembra y sin sustratos artificiales; NaNO2 +B (Stocking) adición de NaNO2 en la siembra y con 150% de adición de sustratos artificiales; Control sin adición de NaNO2 y sin substratos artificiales. La densidad de siembra utilizada inicialmente fue de 400 ind m -2 / 1.100 ind m -3 durante 30 días (precría). Después de este periodo, los camarones fueron sembrados a 120 ind m -2 /400 ind m -3 por más de 18 días (engorde). La turbidez y los sólidos sedimentables fueron más elevados en los tratamientos sin sustratos artificiales, independientemente de la adición del NaNO2. Las concentraciones de amonio y nitrito fueron inferiores en el control, y las concentraciones de nitrato fueron mayores con la adición de NaNO2 y sin sustratos artificiales. Después del periodo de pre-cría, la supervivencia fue menor en el tratamiento NaNO2 (-20), y al final del período de engorde las biomasas fueron más altas en los tratamientos con adición de NaNO2 en la...
