“…Another 14% of the nitrogen and 21% of the phosphorous dissolves and is used by phytoplankton (Neori and Krom, 1991). The remaining nitrogen and phosphorous mainly stimulates bacteria, fungi and protozoa production, which in turn may be consumed by zooplankton (Tang, 1970;Langis et al, 1988). In the present study, artificial feed significantly affected the availability of food.…”

“…Development of biofilm on substrates in aquaculture systems can act as in situ biofilter for reduction of harmful ammonia load (Joice et al, 2002;Rajesh et al, 2008;Bharti et al, 2016). Langis et al (1988) recorded lower ammonia in aquaria harbouring bacterial biofilm on glass panels.…”

Effect of artificial substrates on growth and survival of giant freshwater prawn Macrobrachium rosenbergii (de Man, 1879) in the nursery and grow-out rearing was evaluated. Nursery rearing was conducted for a period of 35 days in nine 1 m 3 cement tubs with 15 cm soil base. Three tubs without substrates served as control (C) while three tubs each with 200 g of sugarcane bagasse (SB) or 200 g of paddy straw (PS) formed the treatments. Each tub was stocked with 15 post-larvae (mean weight, 0.01 g). Grow-out rearing was conducted for 90 days in six 25 m 2 cement cisterns, of which three cisterns without substrate served as control (C) and three with 5 kg sugarcane bagasse (SB) served as treatment. Each cistern was stocked with 25 juveniles (mean weight, 0.55 g). The average phytoplankton and zooplankton abundance in water as well as algae and food organisms attached on the substrate in the nursery phase was greater in bagasse than in paddy straw treatments. Addition of substrate resulted in higher growth and survival both in nursery and grow-out phase. Prawns grown in cisterns provided with substrates were of more uniform size than those in control cisterns. The study recommends the use of substrate based aquaculture for nursery and grow-out rearing of M. rosenbergii.

“…E. suratensis is a hardy species having good flavour, taste and equal nutritional value as compared to other animal food products. Submerged substrates that provide sites for the development of a microbial community not only serve as food source for the reared animals but also improve water quality (Langis et al 1988;Ramesh et al 1999;Thompson et al 2002). It sequesters excess nutrients (Van Dam et al 2002) and improves health of cultured organisms (Shankar and Mohan 2001).…”

Effect of biofilm on water quality and growth of Etroplus suratensis (Bloch, 1790)

An experiment was conducted to compare the efficiency of biofilm production in natural and artificial substrates and to study their effect on water quality and growth of Etroplus suratensis. Four different substrates were used for biofilm formation: paddy straw (T1), sugarcane bagasse (T2), polyvinylchloride (PVC) pipe (T3) and plastic sheet (T4). The experiment was carried out in mud-bottomed fibre-reinforced plastic tanks (300 L) in triplicates. About 3000 cm 2 surface area (600 g) of each substrate was suspended in water supplemented with fertilizers. Only cow dung and urea were applied in control tanks. The tanks were stocked with 25 fishes with average weight of 9.1 ± 0.22 g. The overall mean value of heterotrophic bacteria in substrate was found higher in straw followed by bagasse, plastic and PVC. The dominant genera of bacteria in the substrate were Bacillus, Pseudomonas and Micrococcus in that order of preponderance. The mean phytoplankton and zooplankton density on the substrates were higher in bagasse followed by straw, plastic and PVC. The biofilm developed on the substrate significantly reduced the ammonia nitrogen and nitrite-nitrogen content of water. The growth of fishes was significantly (P \ 0.05) higher in substrate-based treatments than that in the control with better results in bagasse followed by straw, plastic and PVC. The conclusions of the present study are that biofilm produced on natural substrates, especially on bagasse, enhanced growth of E. suratensis and reduced the necessity of water exchange during the culture, which certainly decreases the cost of Etroplus production.
