Length–Weight Relationships And Condition Factors Of 16 Fish Species From Northern Tunisian Coasts, Mediterranean Sea

The aim of this study was to investigate the length–weight relationships of 16 commercial fish species from Northern Tunisian coasts. A total number of 1853 fish specimens were collected between March 2015 and December 2016. Fulton’s condition factor (K) and the length-weight parameters were estimated. There was correlation between the fish total length and weight (R2 range: 0.56 to 0.98). The K values ranged between 0.2±0.03 and 2.6±0.3. The values of b parameter ranged from 2.37 and 3.43 and intercepts (a) between 0.001 and 0.056.
