“…In addition, overstocking density can distress feed uptake as well as conversion efficiencies in fish [46]. These phenomena were also proven in the experiment of Chattopadhyay et al [47]; Mane et al [19]; Yengkokpam et al [3] which fully supported our findings. Nevertheless, some air-breathing catfish, e.g., Clarias gariepinus, Pangasius bocourtiI, Pangasius sutchi can cope with extremely high stocking density [6,8,48].…”

“…However, the cultured species in this experiment do not have the ability to exploit air oxygen and adapt to poor water quality. Hence, these species are sensitive to overstocking density which inversely affects fish growth and feed efficiencies at higher stocking densities [19,49].…”

“…In additon, water quality can rapidly turn down in fishponds due to using the water in personal hygiene, bathing of cattle, washing dishes, and other utensils, etc. However, the optimal production of fish totally relies upon the physical, chemical, and biological qualities of water [18], along with the density and ratio of fishes [19].…”

“…The carp species, Gibelion catla, Labeo rohita, Cirrhinus cirrhosus, and Labeo calbasu are frequently used in polyculture systems in Bangladesh. Although a few experiments have been conducted to optimize the stocking density of each of these species [19][20][21][22], studies' regarding the stocking density using the advanced fingerlings for combined rearing of these species has not been conducted yet in the homestead ponds. Therefore, the goal of this study was to know the growth performance, yield and benefit-cost using advanced carp fingerling with an aim to inform further research to optimize (or maximize) income generation (and nutrient availability) in the coastal area of Bangladesh.…”

Coastal homestead ponds are flooded during the rainy season and only hold water for five to six months. For coastal rural people, these ponds have a substantial impact on household nutrition and income generation. However, choosing the right culture techniques, stocking density, and seed size are necessary for fish aquaculture to be effective in this sort of seasonal pond. Hence, an adaptive field experiment was conducted to reveal the growth performance, yield and cost–benefit using advanced carp fingerling at different stocking densities in homestead ponds. Advanced fingerlings of Gibelion catla, Labeo rohita, Cirrhinus cirrhosus, and Labeo calbasu with the mean individual stocking weight of 243 ± 1.87 g, 223.56 ± 2.35 g, 155.89 ± 1.69 g, and 158.72 ± 1.35 g, respectively, were stocked at three different stocking densities, e.g., 825 kg ha-1 in T1, 560 kg ha-1 in T2 and 370 kg ha-1 in T3 and reared for 5 months. Homemade supplementary feed with protein content of 24.25% was supplied twice daily. The specific growth rate (SGR) was recorded highest at T3 for all the cultured species as L. rohita (1.15 ± 0.01% day-1), followed by G. catla (1.12 ± 0.004% day-1), L. calbasu (1.09 ± 0.01% day-1), and C. cirrhosus (0.98 ± 0.002% day-1), respectively. An inverse relationship was detected between fish growth and stocking density for all treatments. A similar pattern was observed in the survival rate, where reduced survival rates were recorded at T1 for all species. Significant variation (p < 0.05) was found among the treatments in terms of final weight, SGR, and survival rate. Economics of the carp polyculture also showed the highest net benefit (2609.77 ± 2.02 USD ha-1) and benefit–cost ratio (2.06 ± 0.002) at T3. Rearing of fish at 370 kg ha-1 stocking density yielded 129.21% and 110.96% higher production in T3 than T1 and T2, respectively. Overall, T3 treatment was more appropriate than T1 and T2 due to its low FCR, low investment but high survival rate, and net return. Therefore, stocking homestead ponds with advanced carp fingerling with a density of 370 kg per ha can be suggested as for increasing fish production and benefit in the homestead ponds of coastal rural area. In addition, further research is recommended to find out the effects of feeding and sources of seeds on the production performances.

“…The pronounced growth suppression with squeezing of photoperiod indicated increasingly adverse effect of darkness on fingerling growth and can be used as a tool for seed stunting. Observation of reduced survival with increased rearing density in the second part of this study was obvious as reported earlier in carps (Jena et al 1998;Chakraborty and Mirza, 2007;Rahman and Marimuthu, 2010;Mane et al 2019 andFatima et al 2018). Papoutsoglou et al (1979) and Leatherland (1993) attributed the reason for such lower survival to decreased average food consumption by individual fish with increased density while Narejo et al (2005) attributed it to availability of less living space in addition to food.…”

Background: Seed stunting is a process of suppressing the normal growth of fish by manipulating various factors affecting the growth process. The present study aimed at evaluating the influence of varied photoperiod and stocking density on the growth and survival of catla (Catla catla) during the stunting process. Methods: Five treatments including control were used in triplicate and stocked with catla fry (0.84 g, 38.8 mm). Control, T-1 and T-2 groups were stocked with fry at 20 m-3 densities and maintained at 12 hours light and 12 hours darkness (12L:12D), 6L:18D and 0L:24D, respectively to study the influence of varied photoperiod. T-3 and T-4 were stocked with fry at 30 and 40 m-3 densities respectively to study the effect of crowding on the growth. Control at 20 m-3 density and 12L:12D photoperiod served as control for both the studies. Result: There was a significant reduction in the survival, harvested body weight, total length and specific growth rate in the treatments T-1 and T-2 as compared to the control (P less than 0.05). Though these attributes were statistically similar (P greater than 0.05) between T-1 and T-2, the values were relatively higher in T-1 suggesting considerable photoperiod effect on fish growth. Similarly, the HBW, total length and SGR significantly reduced from T-3 to T-4 with increased density depicting effect of crowding on growth. Such results indicated that both increased stocking density and decreased photoperiod lead to growth suppression and can be used as tools for seed stunting in catla.
