Abstract:

Mortality and recruitment pattern of Etroplus suratensis (Bloch, 1790) from Chilika Lagoon, Odisha was studied using length-frequency based analysis to evaluate the length at age, mortality rates and recruitment pattern. The study revealed that the total mortality, Z (2.265/yr) natural mortality, M (0.87/yr) and fishing mortality, F (1.3/yr). The present study also revealed that the probability of capture at L25, L50 and L75 as 19.06 cm,21.75cm and 24.45 cm respectively and E10, E50 and Emax as 0.504,0.322 and 0.649 respectively. The study of the recruitment patterns of E. suratensis also revealed of two annual recruitment.
