“…Reduction of dietary protein level without affecting growth performance of cultured shrimp in the presence of biofloc has been reported by several authors (Hari et al, 2004;Ballester et al, 2010). This is in accordance with earlier investigation by several authors (Arnold et al, 2009;Asaduzzaman et al, 2009Asaduzzaman et al, , 2010 which revealed that the growth was significantly greater when carbon was applied in shrimp culture ponds with zero water exchange model. Inclusion of biofloc as a dietary ingredient in shrimp diet was found to improve the growth performance of P. vannamei (Ju et al, 2008b;Kuhn et al, 2009Kuhn et al, , 2010.…”

The concept of "biofloc technology" is changing the facet of intensive aquaculture with scope to attain high productivity in a sustainable manner. In biofloc, dense heterotrophic bacterial community is developed through C:N ratio manipulation, where the system becomes bacterial dominated rather than algae dominated and takes care of the wastes generated through in situ bioremediation. Protein is utilised in two ways; as feed for the shrimp and as microbial floc when the heterotrophic microbes convert the nitrogenous wastes into protein. It also promises a healthy rearing system, which is increasingly identified as one possible solution for disease problems especially those striking at early stages. The purpose of this study was to evaluate the effect of biofloc and periphyton technology (BPT) on the growth and immunomodulatory performance of Pacific white shrimp Penaeus vannamei during nursery and grow-out culture. The experimental BPT treatments with three tier substrate system with molasses as carbohydrate (CHO) source were compared with the conventional autotrophic system. The immunomodulation and cumulative percentage mortality upon challenge with pathogenic strain of Vibrio parahaemolyticus were assessed in the reared animals. We have successfully demonstrated the BPT based nursery and growout systems for P. vannamei with the advantage of providing significantly (p<0.05) better growth (27.6% improvement in average body weight, ABW) and feed utilisation (31% improvement in feed conversion ratio, FCR). A production level of 4-4.5 kg m -3 of water was achieved through this BPT system registering a significant improvement over the conventional system (p<0.05). The cumulative percentage mortality following pathogen challenge was significantly lower (p<0.05) in the biofloc grown shrimps compared to that of the control group, thus showing better resistance to pathogenic challenge. Furthermore, the biofloc reared shrimp did exhibit significant improvement in non-specific immune response in terms of serum phenoloxidase activity and total haemocyte counts possibly suggesting potential immunostimulatory role of the biofloc associated heterotrophic bacteria. This eco-based technology as revealed through our studies brings substantial improvement in productivity, minimising water requirement, recycling in situ nutrients and organic matter in turn improving farm biosecurity, augmentation of natural food, improvement of FCR and better health of the cultured shrimp.

“…Water quality of fish ponds is influenced by various factors that include the feeding habit of the cultivated species, stocking density, and the quality and quantity of nutrient input through fertilizer and feed. Decomposition and accumulation of organic matter also affects water quality (Asaduzzaman et al, 2009). Inadequate conditions of water quality affect growth, reproduction, health, survival and quality of fish life, jeopardizing the success of aquaculture (Lourenco et al, 1999).…”

Two experiments were conducted using plant substrates viz. bamboo (Bambusa vulgaris), ambay (Cecropia pachystachya) and leucaena (Leucaena leucocephala) without and with fish to evaluate their suitability for periphyton development, and influence on water quality and growth performance of jaraqui (Semaprochilodus insignis). In the first experiment of 45 days, carried out with only the substrates, periphyton growth and water quality were assessed, while in the second experiment of 120 days fish growth was monitored, in addition to periphyton development and water quality. The best growth of periphyton was observed on bamboo, followed by ambay and leucaena. Bamboo grown periphyton had the highest chloropyll-a (39.59 µg/cm 2 ) and protein (24.42%) content. All the water quality parameters monitored were within the limits suitable for aquaculture. Fish of av. length 6.5±0.15 cm and av. wt. 5.83±0.23 g stocked at a density of 1 per m 2 attained the best final av. length of 11.23±0.69 cm and av. wt. of 34.34±2.05 g in bamboo installed tanks, indicating its superiority as a substrate. Jaraqui growth was higher by 76.65, 53.55 and 25.41% in bamboo, ambay and leucaena treatments over the control with no substrate.

“…The substrate-based aquaculture systems aim to develop plenty of algae and bacteria biofilms (periphyton) on any submersible surfaces present in the rearing water (Schrader, Green, & Perschbacher, 2011). Periphyton can be efficiently used by, for example, tilapias as a food source (Asaduzzaman et al, 2009). Moreover, nitrifying bacteria can act as biological filters, by removing ammonia and nitrite from the water, and colonize those substrates (Schveitzer et al, 2013b).…”

ABSTRACT. The present study aimed to assess the possible beneficial effects of the integration between bioflocs and periphyton to the Nile tilapia's water quality and growth performance. There were four treatments with five replicates each: (1) Control: green waters, (2) Periphyton: substrate-based system, (3) BFT: bioflocs technology for aquaculture, and (4) Biophyton: integration between bioflocs and periphyton. Fish (1.63 ± 0.07 g) were reared for 10 weeks in twenty 250 L outdoor tanks. Two polyethylene boards were vertically set out in the Periphyton and Biophyton tanks as underwater substrates. The C: N ratios of water in the BFT and Biophyton tanks were adjusted to 15:1 with dry molasses applications. The concentrations of total ammonia nitrogen were higher in the Control and Periphyton tanks than in the BFT and Biophyton ones. On the other hand, the concentrations of reactive phosphorus were higher in the BFT and Biophyton tanks than in the Control and Periphyton ones. The fish final body weight, specific growth rate and fish yield have not differed between the tanks. The integration between bioflocs and periphyton has not brought clear benefits to tilapia culture on water quality and growth performance.Keywords: aquaculture, Oreochromis niloticus, water quality.Integração entre bioflocos e perifíton em tanques de cultivo da tilápia do Nilo RESUMO. O presente trabalho teve por objetivo determinar os possíveis efeitos benéficos da integração entre bioflocos e perifíton na qualidade de água e no desempenho zootécnico da tilápia do Nilo. Trabalhou-se com quatro tratamentos com cinco repetições cada: (1) Controle: águas verdes, (2) Perifíton: sistema de cultivo baseado em substrato, (3) BFT: tecnologia bioflocos para aquicultura e (4) Biofíton: bioflocos + perifíton. Os peixes (1,63 ± 0,07 g) foram mantidos por dez semanas, em 20 tanques externos de 250 L. Duas pranchas de polietileno foram posicionadas verticalmente, nos tanques Perifíton e Biofíton, como substratos submersos. A relação C: N da água dos tanques BFT e Biofíton foi ajustada para 15:1 pela aplicação de melaço à água. As concentrações de nitrogênio amoniacal total foram maiores nos tanques Controle e Perifíton do que nos tanques BFT e Biofíton. Por outro lado, as concentrações de fósforo reativo foram maiores nos tanques BFT e Biofíton que nos tanques Controle e Perifíton. O peso corporal final, a taxa de crescimento específico e a produtividade de peixe não diferiram entre os tanques. A integração entre bioflocos e perifíton não apresentou claros benefícios para a criação da tilápia, em relação à qualidade da água e ao desempenho produtivo.Palavras-chave: aquicultura, Oreochromis niloticus, qualidade de água.
