We are trying to estimate the biomass of adult snook in Brazilian estuaries where underwater visual census methods cannot be used. A method using gillnets perhaps? Thank you.

We have found methods mostly for juvenile fish, such as those listed in Rozas and Minello 1997 (Estimating Densities of Small Fishes and Decapod Crustaceans in Shallow Estuarine Habitats: A Review of Sampling Design With Focus on Gear Selection. Estuaries Vol. 20, No. 1, p. 199-213 March 1997). However any method for young adults or adults in mangrove estuaries will be most welcomed. Thank you.
