Length-weight relationships andrelative condition factor of fish inhabiting the marine area of the Eastern Mediterraneancity, Tripoli-Lebanon
Abstract
Length-weight relationships (LWRs) and relative condition factor are of great importance in fishery
assessment studies since it provide information about the growth of the fish, its general wellbeing,
and fitness in a marine habitat. LWRs for 9 fish species collected from the marine area of Tripoli-El
Mina, North Lebanon, were established, and their growth condition was evaluated. The results indicated
that almost all captured species exhibited a negative allometric growth and tended to be thinner. A significant
difference was observed between b values during the warm and cold periods for Liza ramada,
Oblada melanura and Epinephelus costae. In terms of seasonal variation, Liza ramada exhibited a positive
allometric growth only in winter, while Oblada melanura had a positive allometric growth during the
summer. The relative condition factor (Kn) fluctuated between 0.99 and 1.00, indicating a state of wellbeing
for these fish species. The current study provided the first baseline data about LWRs and relative
condition factor of fish species from the Eastern Mediterranean city of Tripoli. Such data is valuable for
establishing a monitoring and management system of these fish species.
