“…Similarly, the survival rate of African catfish in cages was also not clearly influenced by stocking density (Hengsawat et al 1997). This is in agreement with the results also reported for the pond culture of African catfish (Hogendoorm and Koops 1983), cage culture of Nile tilapia (Daungsawasdi et al 1986), cage culture of tambaqui Colossoma macropomum in lake (Gomes et al 2006), cage culture of sutchi catfish Pangasius sutchi (Rahman et al 2006), and cage cultures of African catfish and vundu catfish Heterobranchus longifilis (Toko et al 2007).…”

“…The lower yield and longer grow-out period in the culture of Asian river catfish when compared with the African catfish were probably caused by differences in the biology and environmental requirements of the two species. African catfish grow quickly, are omnivores (Hengsawat et al 1997), and can be grown at very high densities because they are air-breathers and have a relatively high tolerance to poor water quality conditions (Toko et al 2007). Asian river catfish are also omnivores; however, they are not air-breathers.…”

Asian river catfish (Pangasius bocourti Sauvage, 1880) were cultured at five different stocking densities in cages (submerged volume 1 m 3 ) suspended in a dugout pond from August to November 2009. Pangasius bocourti fingerlings (mean weight 27.09 ± 0.54 g) were stocked at densities of 12, 25, 50, 100, and 200 fish m -3 . At the end of 3 months, the harvest weights (gross yields) were, respectively, 2.05 ± 0.30, 5.20 ± 0.31, 10.60 ± 0.42, 19.98 ± 0.78, and 42.37 ± 0.41 kg m -3 . The mean fish weights among the stocking densities of 25, 50, 100, and 200 fish m -3 were not significantly different, but were significantly higher than that of the 12 fish m -3 density. The specific growth rates among high stocking densities of 50, 100, and 200 fish m -3 were not significantly different; however, they were significantly higher than those of the low stocking densities of 12 and 25 fish m -3 . Asian river catfish performed poorly at the lowest density. The results indicate an initial lower stocking threshold for Asian river catfish of above 5.20 kg m -3 . The Asian river catfish cultured in small cages placed in a pond reached the desirable market size ([200 g) within a 90-day grow-out period. The results show that the maximum yield for Asian river catfish during a 3-month production cycle was not reached.

“…Esse resultado corrobora aquele encontrado por Toko et al (2007) Tabela 3 -Composição química da carcaça, na matéria natural, de pacus em tanque-rede criados em três densidades de estocagem Na composição química dos peixes, o teor de extrato etéreo foi a única variável que sofreu influência significativa (P<0,05) da densidade de estocagem. Os menores valores para esse parâmetro foram encontrados nos animais estocados em maior número, que diferiram daqueles cultivados em menor densidade de estocagem e foram equivalentes à densidade intermediária.…”

RESUMO -O objetivo neste trabalho foi avaliar o manejo, as características eritrocitárias e o nível de glicose sanguínea de pacus (Piaractus mesopotamicus) estocados em diferentes densidades em tanques-rede. Foram utilizados 2.700 peixes com peso inicial de 142,11 ± 10,54 g, distribuídos em nove tanques-rede de 5 m 3 de volume útil durante 240 dias. O delineamento utilizado foi o inteiramente casualizado, com três densidades (200, 300 e 400 peixes por tanque), cada uma com três repetições. Densities of farming did not influence carcass yield, but they affected total length, which was higher in fish raised in low density, which did not differ from those raised in intermediate density. Fish raised in lower density showed the greatest lipid deposition, but they did not significantly differ from those stocked in intermediate density. Erythrocyte variables like total erythrocytes, hemoglobin, hematocrit, average corpuscular volume, average corpuscular hemoglobin concentrations and average corpuscular hemoglobin did not present statistical differences among the used densities and they remain in the normal range for the species. Levels of glucose in the blood did not differ significantly among the analyzed densities. Stocking densities do not influence erythrocyte parameters, glucose level neither carcass yields of pacu fish. Density 200 fish/cage results in higher final weight and weight gain; however, it reduces productivity per area and increases lipid deposition of the fish. IntroduçãoO Brasil possui inúmeras espécies de peixes autóctones com potencial zootécnico para a criação em tanques-rede. Entre elas, destaca-se o pacu, Piaractus mesopotamicus (Holmberg, 1887 inserir nas referências), que é representante da superordem Ostariophysi, cujos peixes são os de maior valor comercial na pesca e na piscicultura brasileira (Urbinati & Gonçalves, 2005).Muitos fatores podem interferir no período de criação desses peixes. Entre esses fatores, destaca-se a densidade de estocagem, que pode afetar diretamente o crescimento.

“…Limited information is available regarding the body composition of A. marmorata grown in different stocking densities. Previous studies have investigated the effects of stocking density on the body composition of African catfish, vundu catfish, and rainbow trout (Trenzado, Morales, & Higuera, 2006;Toko, Fiogbe, Koukpode, & Kestemont. 2007).…”

We conducted a 71-day experiment to investigate the effects of stocking density in a recirculating aquaculture system (RAS) on the growth performance, body composition, digestive activity, and blood biochemical parameters of the marbled eel Anguilla marmorata. We stocked marbled eel in 1.0 m 3 tanks at stocking densities of 12, 20, and 28 kg/m 3 , which were designated the low-density (LD), medium-density (MD) and high-density (HD) groups. The fish weighed 169.72 ± 2.75 g at the baseline level. Results revealed that the fish in the LD and MD groups had a higher ash content than fish in the HD group. The crude lipid content was significantly lower in the MD and HD groups than in the LD group. The protease activities in the stomach and intestine did not differ among the three groups. The total protein and aspartate aminotransferase levels were higher in the LD group than in the MD group. The alanine aminotransferase level was significantly lower in the LD group. These results indicate that a greater increase resulted in stress and significantly affected the growth of the fish. The optimum stocking density of A. marmorata can be achieved at 20.0 kg/m 3 in a RAS.
