| Abstract: | The length to weight ratio (LWR) was used to estimate populations of four fish species sampled on the Amazon coast of the state of Maranhão, Brazil. The fishes were sampled in 2018 and 2019 by artisanal coastal fishing, using gillnets (0.20–0.60 mm). The parameters a and b of the equation WT = a LTb were estimated. The obtained LWRs were WT = 0.06LT2.93, (r2) = .989 for Oligoplites saliens; WT = 0.061LT2.57, (r2) = .982 for Peprilus crenulatus; WT = 0.014LT2.80, (r2) = .985 for Bagre bagre; and WT = 0.035LT3.21, (r2) = .981 for Nebris microps. |
