Arsenic effects on growth parameters of Indian prawn, Penaeus indicus

Chronic toxicity test was conducted for 28 days with post larval stages of Penaeus indicus to arsenic for studying the changes associated with growth pattern, specifying the length, weight and condition factor. Arsenic exposures produced significant (P 0.05) effect in terms of length, weight and deteriorated the condition factor of the test animal. Differentiation in relation between the condition factor and geometric increase in the concentration was significant (P 0.05; 0.01). Significant (P 0.01) reduced growth was observed in 40, 80 and 160 μg/l arsenic concentrations.
