“…Among the cultured fish and crabs, significant variation ( p < 0.01) was noticed for average final body weight, SGR, DWG, etc. Growth rate of grey mullet used in the present study was much higher compared with earlier reports (Biswas, Ananda Raja, et al., ; James, ; Shofiquzzoha et al., ). For example, M. cephalus recorded highest average SGR, 2.43 ± 0.06% per day compared with 1.6 g % per day SGR and 92.29 ± 4.36 g body final weight gain reported in 6 month polyculture of mullets with tiger shrimps (Biswas, De, et al., ).…”

“…It is reported that in 5 month culture lesser mullets attained a lower growth rate, 0.28 to 0.35 g DWG and 0.40 to 0.48% per day SGR compared with fast growing M. cephalus (Karapanagiotidis et al, 2004). However, in the present study L. parsia and L. tade recorded better growth performance (Table 3) compared with earlier observation (Biswas, Ananda Raja, et al, 2012;James, 1996;Shofiquzzoha et al, 2001).…”

“…Scientific grow-out farms of S. serrata yield 1.5-2 t/ha per each crop of 6 months with an individual weight of 300-350 g per crop (Linder, 2005;Trino et al, 1999). Polyculture of milkfish or mullets with shrimps recorded an average productivity of 500-1,800 kg/ha (Biswas, Ananda Raja, et al, 2012;James, 1996;Nammalwar & Kathirvel, 1988;Shofiquzzoha et al, 2001). The productivity level noticed in the present polyculture pond trials was much higher than those reported earlier.…”

“…Herbivorous finfish such as mullets, Mugil cephalus, Liza tade, L. parsia and milkfish, Chanos chanos forms compatible species for polyculture apart from its consumer preference and market price. There are various reports about the polyculture of shrimp with milkfish (Biswas, Ananda Raja, et al, 2012;Eldani & Primavera, 1981;James, 1996;Kuntiyo & Baliao, 1987;Pudadera & Lim, 1982), mullets (Biswas, Ananda Raja, et al, 2012;James, 1996;Shofiquzzoha, Islam, & Ahmed, 2001), tilapia (Tian et al, 2001;Yuan, Yi, Yakupitiyage, Fitzimmons, & Diana, 2010) and bivalves (Hopkins, Hamilton, & Sandifer, 1993;Tian et al, 2001). However, in the last two decades, outbreak of white spot viral disease in shrimp culture demands high biosecurity, with minimum or zerowater exchange farming systems.…”

et al. 2018

To compare production and economic performance of polyculture systems with different species combinations, a 210-day trial was carried out. In the first combination (T1), milkfish (Chanos chanos) and mudcrabs (Scylla serrata), and in the second (T2), mullets (Mugil cephalus, Liza tade and Liza parsia at 0.5:0.5:0.5 ratio) and mudcrabs were stocked keeping fish and mudcrabs at 15,000 numbers per ha, respectively, in both treatments. The finfish were fed floating pellet at 2%-3% and mudcrabs were fed fresh and farm made feed at 5%-8% body weight. Growth parameters of mudcrabs were similar in both T1 (407.64 ± 105.78 g) and T2 (418.89 ± 105.24 g), with no significant differences. Among finfish, M. cephalus attained highest final body weight, 241.55 ± 26.44 g followed by milkfish, 200.46 ± 11.82 g whereas lowest growth noticed in L. parsia (63.69 ± 6.62 g). Length-weight analysis of fish indicated negatively allometric growth (b < 3) for grey mullets, parsia and milkfish while L. tade recorded perfect cube low (b = 2.99). Male mudcrabs recorded positive allometric (b = 3.3) and female crab exhibited negative allometric growth (b = 2.68). The total productivity was 4,533 and 3,694 kg/ha with mudcrab contributes 53.69% and 60.56% to the total productivity in T1 and T2 respectively. The economic analysis indicated benefit-cost ratio (BCR) of 1.57 and 1.73 in T1 and T2 respectively with 10% and 35% insignificant increase (p > 0.05) in BCR and profit per kg, respectively, in T2 compared with T1. The study elucidates polyculture of mudcrabs with finfish can be a taken up as a profitable venture for sustainable diversification of brackishwater farming in Sundarbans. . chanos, L. parsia, L. tade, M. cephalus, polyculture, S. serrata K E Y W O R D S C
