The growth and mortality of the picarel, Spicara smaris (L., 1758), were determined from specimens collected on the eastern Turkish Black Sea coast during September and October 1991 and 1992. From the length-age data for both sexes and all areas combined, the following population parameters were estimated: length-weight relationship, W = 0.005L3.26; Von Bertalanffy growth constants, W∞(g) = 87.20, L∞(cm) = 20.05, K = 0.44, t0 = -0.01; total mortality and its components, Z = 1.58, M = 0.87, F = 0.71. The steady-state yield per recruit model of Beverton and Holt (Fish. Invest. Minist. Agric. Fish. Food, 19: 533 (1957)) was applied to evaluate regulatory options for the picarel stock. © 1995.
