Population Dynamic and Stock Assesment of White Seabream Diplodus sargus (Linnaeus, 1758) in the Coast of North Siani
In the present study fisheries, population dynamic and stock assessment of Diplodus sargus in the coast of North Siani (Eastern Mediterranean, Egypt) studied. Length weight relationship, catch length structure, length scale relationship, total length by the end of each year of life, growth in weight, Von Bertalanffy parameters, the values of (total, natural and fishing mortalities), survival rates, Approximate maximum length with the highest biomass of D. sargus and approximate maximum age tmax. Also Cohort analysis (VPA, age based) which represent the estimated values of the population numbers, survivors, natural and fishing mortalities for each year of life of D. sargus were studied.
