Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2014, Vol 5, Issue 2
Abstract
The age, growth, of Mullus surmuletus, caught in Mostaganem (Northwest Algerian Sea) between January and December 2009, were investigated. Sex ratio female to male was 1:1.60. The total length of females ranged from 12.5 cm to 23 cm and of males from 12.3 cm to 22.5 cm. The length-mass relationship for all individuals can be described by the parameters a =0.009 and b = 2.934. Fish aged 0-7 years were present in the samples. The parameters of the Von Bertalanffy growth equation obtained for females were L∞= 24.70 cm, k = 0.37 cm / year, and t0=- 0.37 year. For males L∞= 25.52 cm, k = 0.32 cm / year, t0 = - 0.71 year. Significant differences were found in the growth parameters between males and females.
