Abstract

011 tile basis of data on N. japortic~ts from trawl landings at Kakinada, the von Bertalanffy paramctrt's of growth in length are estimated as Llm = 339 mm, K = 0.52 per year slid b, - -4.16 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.
