Length–weight relationships of six marine fish species from the coast of Ghana

Abstract

Length-weight relationships are very useful for fisheries research because they: (a) allow growth-in-weight equations for use in stock assessment models; (b) help estimate biomass by means of length observations; (c) enable us to obtain an estimate of the condition of the fish; and (d) are useful for interregional comparisons of life histories in certain species, provided all investigators employ a fully comparable (standardized) sampling methodology (Kara et al., 2018).The LWR equation parameters a and b are important in stock assessment studies when obtained together with a number of population relevant data such as sex, ratio, age at first maturity and fecundity data (Simon & Mazlan, 2008). The present contribution aims to provide new LWRs which includes a wider size range or a larger TLmax compared to existing studies. | MATERIAL S AND ME THODSThis study was conducted at five locations, Tema, Nungua, Sakumono, Prampram and Kpone in the Greater Accra region, Ghana.Inhabitants of these coastal community are mostly engaged in fishing and its related activities.
