Length-Weight Relationships and Condition Factors of Bony Fishes Inhabiting the Southern East Mediterranean Sea, Bardawil Lagoon, Egypt
The present study was designed to list the species of bony fish in Bardawil Lagoon and document their length-weight relationships (LWRs) and the condition factor (K) during the heavy using small trawling period (Kalsa net). The catch in the present work, identified to species level, consisted of 20 species, 14 of which were bony fish belonging to eight families. In total, 2072 specimens (weighing 250 Kg) of bony fish were collected and investigated. The determination coefficient (R2) of LWRs ranged from 0.929 to 0.984, indicating strong relationships. In general, the b-value of LWRs for the investigated species ranged from 2.84 to 3.42. Based on the results of the t-test, b-values in the present study revealed that nine species showed isometric growth and the remaining were allometric. The average values of K were 0.92, 0.88, and 1.033 for autumn, spring, and summer, respectively. Moreover, the values of the relative condition factors ranged from 0.97 to 1.03. Results showed that Bardawil Lagoon has a good environmental condition for better fish growth. The data from the present study can be valuable as a reference for the management and sustainability of these species in Bardawil Lagoon and the Mediterranean basin.
