Length-Weight Relationships and Growth Parameters of Bogue, Boops boops, (Linnaeus, 1758) from Didim, South-eastern Aegean Sea
Abstract
In this study length-weigth relationships and and growth parameters of Boops boops (Linneaus, 1756) sampled from Didim coasts, South-eastern Aegean Sea were investigated. A total of 361 specimens (226 females and 135 males) were sampled. The mean length and weights were 18.57 ± 2.46 cm and 60.74 ± 23.60 g for females and 17.63 ± 3.63 cm and 60.50 ± 36.87 g for males, respectively. The overall sex ratio (F:M) was determined as 1:1.67 (χ², P < 0.05). Length-weight relationships for all individuals were described by the parameters a = 0.0113, b = 2.93 and r² = 0.974. The exponent of the b parameter represented negative allometric growth in females, isometric growth in males and negative allometric growth in both sexes. Values were statically significant (P < 0.05). The von Bertalanffy growth parameters were calculated as L∞ = 35.34 cm, k = 0.156 year-1, t0 = -2.093 years for females; L∞ = 33.23 cm, k = 0.184 year-1, t0 = -1.268 years for males; L∞ = 41.23 cm, k = 0.117 year-1, t0 = -2.200 years for both sexes. The growth performance index (φ´) was estimated for females, males, and both sexes as 2.291, 2.310, and 2.302, respectively. Age determinations varied from 1 to 5 years and age class III was found dominant in both sexes.
