Özet

Fishery and Population characteristics of Euthynnus alletteratus (Rafinesque 1810) were studied using 695 fishes collected from landing site in Eastern Coast of Mediterranean Sea off Alexandria, Egypt. Eight age groups were recorded -1using vertebrae. Von Bertalanffy growth parameters were estimated as L∞ = 123.4 cm, K = 0.16 year and t0 = -0.59 year. The rate of total mortality (Z), natural mortality (M) and fishing mortality (F) were 1.996, 0.396 and 1.6 respectively. Length at first capture was estimated as 34cm (1.4 year). The results indicate that population is overexploited (E = 0.802) and suffering from high fishing pressure. Cohort analysis and yield per recruit analysis realized that E. alletteratus stock of the Eastern Coast of Alexandria needs a new management strategy for sustainable yield.
