Estimation of growth, mortality and the exploitation rate of the bougue (Boops Boops Linnaeus, 1758) population from the Babadıllımanı (Mersin) Bight
Abstract
This study was performed for the identification to the fisheries biological parametres of (Boops boops Linn., 1758), 314 individuals were obtained by monthly sampling using deep trawl from the Babadıllimanı Bight between May 1999 and April 2000. The lenghts ranged from 7.5-21.4 cm and weight varied between of 3.52- 99.98 g while age composition changed from I to VI. th age group. The examined individuals composed of 49.68% female 50.00% male 3.2% juvenil. The growth peculiarities length-weight relationship were estimated. von Bertalanffy’s growth constants in length and weight were also estimated as L∞=33.62 cm, K=0.109 yıl -1, to=-1.900 yıl and W∞=354.707 g. In additionally for this species mortality were Z=1.2572 year-1, and its components were F=0.9058 year and M=0.3514 year -1; it was also found that the exploitation rate was E=0.7205 year-1. Therefore, the was overfishing on the bogue stock inhabited along the Babadıllimanı Bight.
