Abstract

Oil (lie basis of data on N. japolliclIs from trawl landings at Kakinada, the
von BertalanfIy parameters of growth in length are estimated as L"", = 339 mm,
K = 0.52 per year and 1>0 = -0.16 year. The mortality rates are estimated as
Z = 2.64, M ~, 1.11 and F '" 1.53. The length at first capture is estimated as
120 mm. The yield per recruit analysis shows that increase in effort from the present
level results in reduced yield from the present fishing ground if the cod end
mesh size is not increased.
