Weight–length relationships for twelve cichlid species from Lake Malawi, Africa

Author(s): A. Maruyama, R. Zatha, B. Rusuwa

Abstract: We report weight–length relationships for 12 species of cichlid fishes from Lake Malawi, Africa. In total, we analyzed 255 specimens, collected by SCUBA divers with gill nets and dip nets from the rocky littoral zone of Thumbi West Island at the end of the dry season. The a and b values in the weight–length relationship (W = aLb) ranged from 0.003 to 0.030 and from 2.81 to 3.56, respectively. These relationships may be useful for rapid biomass estimation of this lacustrine fish community, one of the world’s most diverse ichthyofauna, just by experienced divers’ observation.
