“…This improvement in FCR is typical with what has been observed for both improving diet specifications and the use of microbial biomass in other studies (Glencross et al, 1999;2014;Ju et al, 2008;Kuhn et al, 2009). …”

“…However, it can be implied if a constant protein content of the shrimp is assumed and feed intake data is presented (or able to be calculated from growth and FCR data). In such cases, then it can also be realised that in most instances there is an increase in protein retention efficiency occurring with increasing protein levels (to the point of maximal weight gain) and also in some studies with the use of microbial biomass (Bages and Sloane, 1981;Alava and Lim, 1983;Kuhn et al, 2009;Anand et al, 2014).…”

“…The recent development of and use of a range of microbial biomass products has also been reported to achieve significant improvements in growth performance in several shrimp species (Ju et al, 2008;2009;Kuhn et al, 2008;2009;Glencross et al, 2013;2014;Emerenciano et al, 2014). The use of these microbial biomass products has also resulted in success in being able to off-set poorer performance due to a range of formulation changes, including the complete replacement of any fishery derived resources in the diet of shrimp (Glencross et al, 2014).…”

Bioactive factors in microbial biomass have the capacity to offset reductions in the level of protein in the diet of black tiger shrimp, Penaeus monodon

A factorial experiment was conducted with black tiger shrimp (Penaeus monodon) juveniles to determine the effects of varying protein inclusion in the diet and also varying inclusion of a microbial biomass on growth, feed and nutrient utilization when fed in indoor laboratory conditions. The growth performance of the shrimp improved with increasing diet protein level. However, in the absence of the added microbial biomass, this growth performance plateaued at the 480. g/kg protein level. The addition of the microbial biomass improved growth at each inclusion level of both protein and microbial biomass. No plateau in growth was observed with the addition of the microbial biomass. Improvements in feed conversion were seen with increasing dietary protein levels and also the inclusion of the microbial biomass. Examination of the feed intake of each treatment supports that there was a combined effect of an increase in feed intake and improvements in feed conversion that contributed to the improvements in growth performance with the use of the microbial biomass, but the increases in dietary protein level largely influenced growth through improvements in feed conversion

ABSTRACT. The objective of the present work was to assess the possible benefits of the installation of underwater structures for periphyton in bioflocs tanks for Nile tilapia, Oreochromis niloticus, submitted to feed restriction (artificial diet). The experimental treatments evaluated were: (1) BFT: bioflocs technology for aquaculture with no feed restriction; (2) BFT-30: the same as (1) but with feed restriction at 30%; (3) BP: biophyton technology for aquaculture, that is, integration between bioflocs and periphyton in the same rearing unit, with no feed restriction; (4) BP-30: the same as (3) but with feed restriction at 30%. The underwater structures for periphyton in the BP and BP-30 tanks were not able to reduce the concentrations of ammonia, nitrite, nitrate and reactive phosphorus in the water to same respective level found in the BFT and BFT-30 tanks. The underwater structures for periphyton in the BP and BP-30 tanks have not significantly affected fish growth performance. No benefits were obtained by the installation of underwater structures for periphyton in bioflocs tanks submitted to feed restriction on water quality, water microbiology and tilapia growth performance.

“…The contribution of bioflocs on fish production has not been properly quantified yet (Crab, Defoirdt, Bossier, & Verstraete, 2012. ), nor it is clear the relative importance of the heterotrophic bacteria as a food source (Azim & Little, 2008;Anand et al, 2014).…”

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.
