“…In contrast to our results, Yue et al (2012) found that using lysine and methionine in the diet of L. vannamei more amounts of FM could be replaced by SBM, although it should be considered that in their experiment shrimp were not cultured in biofloc system. According to our results, the higher growth performance of shrimp that were cultured in biofloc in comparison to the clear water group is in agreement with previous findings (Ray et al 2011;Irshad et al 2016). Valle et al (2015), replaced fish meal with biofloc flour and protein hydrolysate in the diet of L. vannamei and indicated that biofloc flour is a potential ingredient that can be used as substitute for fishmeal.…”

Different levels of dietary soybean meal (SBM) as a fish meal (FM) replacer, with and without amino acid supplementation, for whiteleg shrimp, Litopenaeus vannamei reared in the biofloc system was examined in eight weeks of feeding trial. Eight experimental diets consisted of a basal diet with 0% FM replacement by SBM provided in clear sea water without biofloc system (S 0 SW), four diets replacing FM at 0% (S 0 ), 33% (S 33 ), 67% (S 67 ) and 100% (S 100 ) by SBM, and three diets replacing FM at 33% (S 33 A), 67% (S 67 A) and 100% (S 100 A) by SBM supplemented with amino acids (methionine and lysine) in the seawater biofloc system. Results of water quality analyses showed significantly lower total suspended solids and nitrate for S 0 SW group than all other treatments. Diets S 0 and S 33 A resulted in higher weight gain and specific growth rate among all groups, with no significant differences with S 33 group. In addition, whole-body protein and amino acid compositions of shrimp fed S 0 SW were lower than most biofloc groups. Haemolymph parameters showed significant differences in total protein, cholesterol and triglyceride between groups S 0 and S 0 SW. Also, superoxide dismutase activity showed a decreasing trend with increasing replacement level. In conclusion, based on these results, SBM could replace up to 33% of FM with or without amino acid supplementation in juvenile whiteleg shrimp diets reared in the biofloc system.

“…The electrical conductivity (EC) of the water was significantly affected by the adjustment of the C: N ratio of water, in which the C: N-adjusted tanks presented the higher values of EC (Table 1). Dry molasses after decomposition releases CO 2 to the water, reducing the water alkalinity and pH (Ray, Dillon, & Lotz, 2011).…”

ABSTRACT. The present work aimed at determining the effects of the association between the periphyton-based system with the bioflocs-based system in the intensive culture of juvenile Nile tilapia (1.56 ± 0.07 g; 72 fish m -3 ), on variables of water quality, growth performance and effluent quality after 10 weeks. The experiment was arranged in a 2 x 2 factorial randomized block design with four treatments and five repetitions each. The factors tested were the following: 'underwater structure' (absence and presence) and 'adjustment of the C: N ratio of water' (no and yes). The final fish body weight, specific growth rate and yield were higher (p < 0.05) in the C: N-adjusted tanks. The presence of submerged structures in the tanks had no significant influence on those same variables. It was concluded that the periphyton-based system is not indicated for intensive farming of Nile tilapia, in which there is a high allowance of artificial feed to fish.Keywords: aquaculture, Oreochromis, limnoculture, limnology.Integração dos sistemas perifíton e bioflocos no cultivo intensivo de juvenis de tilápia do Nilo RESUMO. O presente trabalho teve por objetivo determinar os efeitos da integração do sistema baseado em substrato (perifíton) com o sistema baseado no ajuste da relação C: N da água (bioflocos), no cultivo intensivo de juvenis de tilápia do Nilo (1,56 ± 0,07 g; 72 peixes m -3 ), sobre variáveis de qualidade de água, desempenho zootécnico e qualidade de efluentes, após 10 semanas. O delineamento experimental utilizado foi em blocos ao acaso, em arranjo fatorial 2 x 2, com quatro tratamentos e cinco repetições cada. Os fatores em teste foram os seguintes 'estruturas submersas' (ausência e presença) e 'ajuste da relação C: N da água' (não e sim). Os resultados de peso corporal final, taxa de crescimento específico e produtividade de peixe foram maiores (p < 0,05) nos tanques nos quais se fez o ajuste da relação C: N da água, quando comparado aos tanques sem esse ajuste. A presença das estruturas submersas nos tanques não afetou de modo significativo essas mesmas variáveis. Concluiu-se que o sistema de cultivo de peixe baseado em substrato (perifíton) não é indicado para cultivos intensivos de juvenis de tilápia do Nilo, nos quais há grande entrada de alimento artificial nos tanques de cultivo.

“…The increase in growth performance and feed utilization of the shrimps reared in biofloc were reported by several researchers (Kuhn et al, 2010;Megahed., 2010;Emerenciano et al, 2011;Krummenauer et al, 2011;Ray et al, 2011;Emerenciano et al, 2012;Kim et al, 2014;Ray and Lotz, 2017). In addition to this, biofloc acts as a supplemental feed source which results in the better zootechnical performance (Burford et al, 2004;Kuhn et al, 2008;Megahed, 2010).…”
