Abstract

The stock of Japanese scad Decapterus maruadsi was assessed based on 1864 specimen (combined sexes), collected from the Gulf of Suez during the fishing season 2011/2012. The growth parameters (L∞ & K) have been estimated from length frequency distribution data, and the obtained values were L∞ = 27.31 cm TL and K = 0.53/y. The instantaneous rates of total (Z), natural (M) and fishing (F) mortalities were 1.80, 0.61 and 1.19/y respectively with exploitation ratio (E) of 0.66/y which reflects an over exploitation situation. The estimated length at first capture (Lc) was
12.2 cm, while the length at first sexual maturity (Lm) was 12.3 cm. The relative yield per recruit analysis shows that the stock of D. maruadsi is overexploited and needs to develop a management strategy to conserve and optimize its yield.
