Abstract

Length-weight relationships (LWR) were estimated for 13 fish species which are of economic relevance
in the commercial fisheries of the Gulf of Gabes (southern Tunisia). A total of 2403 fish specimens were
sampled with several fishing gears from October 2008 to September 2009. The sample size ranged from
65 individuals for Coryphaena hippurus to 346 for Euthynnus alletteratus. The b values in the LWR, W =
aLb
ranged from 2.807 to 3.284, with a mean of 3.015 ± 0.102 and intercepts between 0.0011 and 0.0432
with a mean of 0.0139. The condition factor (c.f.) values significantly (p < 0.05) ranged from 0.64 to 1.55.
