中文摘要	The N. randalli fish data consist of 1141 pair of length weight relationship and 24312 length frequencies were measured during 2009 - 2010 survey. The maximum length and weight were 25 cm. and 251 g, respectively. The length weight relationship were a = 0.035, b = 2.744 and R-2 = 0.972. The asymptotic length (L-infinity) and growth coefficient (K) were estimated to 26.25 cm and 0.320 year respectively. The total mortality (Z) was 1.25 year The natural mortality (M) was 0.863, hence the fishing mortality (F) was Z = M = 0.387 year I for N. randalli. The yield per recruit analysis indicated that when t(c) was assumed to be 2, F-max was estimated at 1.3 and F-0.1 at 1.3; while t(c) was assumed to be 1, F-max was estimated at 1.1 and F-0.1 at 0.95. Currently age at first capture is about 1 year and F-current was 0.387, therefore, F-curent was smaller than F-0.1 and F-max. The results during present study indicate that current fishery stock is in sustainable state. However, it is suggested that take some management steps to maintain the stock of N. randalli in Pakistani waters, Northern Arabian Sea.
