“…P. indicus also attained the highest survival in T4 (76.3 ± 7.3%) compared to T2 (59.7 ± 6.3%) and T3 (66.3 ± 5.9%). The periphyton develops on nylon substratum may have served as a food source for the fish, which agree with other reports where periphyton substrates are incorporated in M. cephalus culture ponds (Biswas et al., 2017; Jana et al., 2004). The culture shrimp however may not have efficiently utilized the periphyton and the non‐provision of feed could attribute to the low and uniform growth in the three treatments.…”

“…Although apparent variation for total ammonia nitrogen (TAN) and nitrite‐ N (NO 2 ‐N) was recorded, there was no statistical significant difference among all experimental ponds. The TAN concentration in T3 and T4 was significantly lower during harvest which can be attributed to the consumption of organic matter by the oyster and inorganic matter by periphyton resulting in the reduction in the ammonia‐N concentration (Biswas et al., 2017; Khatoon, Yusoff, Banerjee, Shariff, & Mohamed, 2007; Viji et al., 2014). The primary productivity measures as chlorophyll a concentration (Figure 1) of the water were in a lower range as compared to other reports on polyculture system (Anand et al., 2018; Biswas et al., 2012).…”

Diversification of production systems has been identified as one of the major strategies for the long‐term sustainability of brackishwater aquaculture. On the context of diversification, a 180‐day culture experiment was carried out where four farming systems were tested: monoculture of mud crab, Scylla serrata (T1), polyculture of mud crab, with mullet Mugil cephalus and shrimp Penaeus indicus (T2), polyculture of mud crab with mullet, shrimp and oyster Crassostrea cuttackensis (T3), polyculture of mud crab with mullet, shrimp, oyster along with periphyton net (T4) covering 10% of the water spread area. There was no significant difference in the growth performances of mud crab, shrimp and oyster among the treatment but a significantly higher (p < .05) final average body weight (ABW) of M.cephalus was recorded in T4 (121.19 ± 2.09 g). Production considering only the fed animals (excluding oyster) was significantly (p < .05) higher in T4 (2,115 kg/ha) compared to other treatments. The overall water quality parameters do not vary significantly (p > .05) among the treatment ponds. Although there was no significant difference in total ammonia nitrogen (TAN) and nitrite‐N, highest value was recorded in T2 (56.23 ± 39.47 µg/L and 185.53 ± 110.71 µg/L) and T1 (55.78 ± 32.26 µg/L and 180.83 ± 103.65 µg/L). The results from the current experiment based on water quality and growth of animals showed that there is no negative interaction between the mud crab and other animals stocked in the polyculture pond which indicated that polyculture provides an efficient and sustainable utilization of resources.

“…A steady increase in chlorophyll can result from the periodic fertilization of the ponds. Fertilization helped in continuous propagation of phytoplankton population (Biswas et al ., 2017; Mischke & Zimba, 2004). Formulated feed was developed in the present study by considering the nutrient profile analysis (De et al ., 2019) and nutrient requirement data (unpublished) at different stages of hilsa.…”

Successful captive broodstock development of clupeid fish, hilsa, is one of the major challenges for the artificial propagation of this economically valued fish. The present study provides novel insights into the pond‐reared captive broodstock development of hilsa using artificial feed. In the present study, wild collected hilsa fry (weight 1.35 ± 0.13 g, length 53.84 ± 0.95 mm) were reared in grow‐out ponds for 6 months followed by maintaining them as broodstock in other ponds using formulated feed in both cases. After 6 months of pond rearing, the average body weight and length of fish were 66.76 ± 4.53 g and 184.75 ± 3.65 mm, respectively. In broodstock ponds, hilsa subadults fed with formulated feed (crude protein 41.06%) ensured significant advancement in ovarian maturity with gonado somatic index of 9.09%, enhanced secondary yolk stage oocytes of 91.66% and enlargement of oocyte diameters up to 570 μm. The broodstock reached somatic growth such as average body weight and average body length of 383.80 ± 27.38 g and 339.33 ± 9.68 mm, respectively, with a condition factor of 1.06 ± 0.15. Gut content analysis revealed the better acceptability of the artificial feed. Lipid profiling of muscle and ovary during gonadal maturation revealed mobilization of fat from muscle to ovary and selective retention of some fatty acids (i.e., C14:0, C18:0, C20:5, C22:6 and C20:4) in the ovary, which might help in gonadal maturation. Statement of Significance Successful rearing of wild‐caught hilsa juvenile in captive condition using formulated feed showed its potential as aquaculture species in low saline conditions. Advance stage of maturation in low saline captive conditions showed the possibility for induced breeding of hilsa, a high priced anadromous fish. Mobilization of fat from muscle to ovary and selective retention of some fatty acids in the ovary showed the scope of dietary manipulation for broodstock development of hilsa.

“…It was mainly due to less grazing by fishes on periphyton in T₂ as there was the availability of supplementary feed as well as the extra nutrients received through the leftover supplementary feed (Mridula et al, 2006) [27] . The increase in periphyton biomass indicates that the initial fish has a low overall biomass and low grazing pressure on the surrounding periphyton, while the stable or low periphyton biomass is due to the higher fish biomass at the selected stocking density (Biswas et al, 2017) [46] . Chlorophyll-a value is an indicator of pond productivity and has an inverse relationship with water transparency (Ahmed 1993) [47] .…”

A study was conducted to evaluate the effect of periphyton substrate on plankton dynamics. Sugarcane bagasse is used as a substrate for periphyton growth. Three experimental treatments were included; T0 (Control), T1 (Substrate + feed) and T2 (substrate only). Indigenous fishes like Labeo fimbriatus (Bloch,1795), Barbodes carnaticus (Jerdon,1849) and freshwater prawn, Macrobrachium rosenbergii were stocked in tanks in 3:3:4 ratio at 10000/ha, for a period of 180 days. Bagasse substrate influenced the water quality parameters viz., pH (6.73 -8.17), dissolved oxygen (6.70 -8.50). Low concentration of Ammonia (0.068 -0.140 mg/l) and Nitrite (0.046 -0.082) was observed in substrate based ponds. A decreasing trend was observed in periphyton DM, AFDM and ash content value in both the treatment near the termination of experiment, which indicates effective grazing on periphyton by cultured fish species. Also, pigment concentration was also found high in substrate ponds. The result demonstrate that sugarcane bagasse can effectively use as a substrate for enhancing the population of plankton.
