Culture potentials of brown shrimp, Metapenaeus monoceros (Fab.) under different stocking densities in south-western region of Bangladesh

Abstract

An experiment was conducted to evaluate the production potentials of brown shrimp, Metapenaeus  monoceros under three different stocking densities such as 10, 20 and 30 /m² in treatments T₁, T_{2 ,}and T₃ in brackishwater ponds. After 90 days of culture total production was recorded as 577, 608 and 764 kg/ha in T₁, T₂ and T₃ respectively. Total production was significantly higher (p<0.05) in T₃ compared to T₁ and T_2. Net benefit was recorded as BDT 143,109/ha, BDT 121,825/ha and BDT 162,516/ha in T₁, T₂ and T₃ respectively. Cost benefit ratio was 2.23, 1.80 and 1.91 in T₁, T₂ and T₃ respectively. Net benefit in T₃ (BDT 162,516/ha) was higher than T₁ and T_2. The brown shrimp have high rates of growth, together with that they tolerate wide ranges of salinity and environmental parameters, makes them highly attractive for culture purposes.
