“…For analysis of digestive enzyme activity, 30 fry from each treatment group were sacrificed in the Exp. 1 (Gangadhar et al, 2016). The fry were homogenized in ice cold condition with distilled water (4 ml/g) and centrifuged at 10,000 g for 20 min at 4°C.…”

A study was conducted with non‐conventional ingredients to test their efficacy as fishmeal (FM) replacers in the diet of fringe‐ lipped carp. Labeo fimbriatus first feeding larvae and fry were reared for 30 and 60 days in indoor, 50 L, aerated, circular plastic tanks at 100 and 30 numbers tank−1, respectively. In the first feeding larvae to fry rearing experiment (Exp. 1), the fish were fed with either of the following isonitrogenous and isocaloric diets – live plankton, FM diet, green bottle fly (Lucilia sericata) larvae meal (GBFLM) diet and silkworm pupa (SWP) diet. The fry to fingerling rearing (Exp. 2), was also conducted using the same diets described above except live plankton. All compounded diets were formulated to contain 40% crude protein for the experiment 1 and 35% for experiment 2 and were fed ad libitum. Triplicate tanks were maintained for each treatment in both the experiments. In Exp. 1, the mean final weight of fry was higher with plankton and FM diets, while no difference (p > .05) was observed between FM and GBFLM diets. Weight of fish fed SWP diets was not statistically different from those fed GBFLM diet. No difference (p > .05) in final length, survival and condition factor was recorded. Analysis of digestive enzyme activity of whole fish revealed lower (p < .05) activity of amylase in fish fed plankton. In Exp. 2, no difference (p > .05) was observed between the different diet groups in terms of mean final weight, length, survival and condition factor. Analysis of digestive enzyme activity of whole fish revealed no difference (p > .05) in the activity of digestive enzymes between the treatments except a lower (p < .05) activity of trypsin in FM diet and lipase in FM and GBFLM diets. Since the survival and condition factors of animals is the most important aspect during nursery rearing, similar (p > .05) values recorded in different treatments indicate the possibility of incorporation of these non‐conventional protein sources in the diet of L. fimbriatus during first feeding larvae to fry and fry to fingerling rearing.

“…Nowadays, aquaculture systems are advanced by introducing microbes by applying probiotics, biofilm/periphyton and biofloc technology (Pandey et al, 2014). Among microbial systems, the biofilm-based system found to be cost-effective via reducing considerable quantity expensive supplementary feed compared to a conventional fed system (Gangadhar et al, 2016;Garcia et al, 2016;Ghosh et al, 2019;Milstein et al, 2008). A microbial biofilm is composed of the colonization of diverse groups of micro-and planktonic organisms such as bacteria, protozoa, fungi and algae.…”

A seed rearing experiment was attempted to evaluate the effects of stocking densities in the biofilm-based system reared with pearlspot, Etroplus suratensis on different aquaculture parameters. Pearlspot advanced fry of size (4.67 ± 0.04 cm/1.71 ± 0.03 g) stocked at four different stocking densities viz 50 fish (T 1 ); 100 fish (T 2 ); 150 fish (T 3 ) and 200 fish (T 4 ) m −3 in the biofilm-based rearing system and at the rate of 150 fish m −3 in the clear water fed (CWF) system tanks. The total ammonia nitrogen and dissolved oxygen levels in biofilm tanks with different stocking density were significantly lower than CWF. Diatom was found as dominant plankton in all biofilm treatment tanks in water as well as on substrate. The growth parameters were found to significantly decrease with increasing stocking density in the biofilm-based rearing system. The significant highest individual growth parameters and significantly lowest fish biomass were found in T 1 . Final fish biomass was found to increase with increasing stocking density up to 150 advanced fry m −3 and then reduced due to decreased survival. Body composition analysis of E. suratensis showed increased protein and decreased lipid levels in all biofilm-based rearing system treatments at different stocking densities compared with clear water fed system. The present investigation findings on plankton abundance, growth, body composition and blood parameters at different stocking densities will provide guidelines for selecting appropriate stocking density for pearlspot advanced fry to fingerling rearing in a low saline biofilm-based system without providing a supplementary diet.
