Length-weight and length-length relationships of fishes from the Ouémé River in Bénin (West Africa).

Abstract

The relationships between total (TL) and standard (SL) lengths for 50 fish species and between TL and wet weight for 52 fish species caught in the Oue´me´ River are presented. Relationships between TL and SL are linear. Between TL and weight, the relationships are of the form TW ¼ aTLb. The b values range from 2.3307 to 3.5185. Student’s t-test revealed that 38.5% of the species have b values significantly different from 3.
