Length-weight and length-length relationships of three tidepool fish species in the Amazon Coastal Zone of Brazil

Length-weight relationships (LWR) and length-length relationships (LLR) were analyzed for three species inhabiting tidepools in the Amazon Coastal Zone, two of them non-native. Tidepools were sampled in five beaches along the Amazon Coastal Zone in 2011, and samplings were carried out using hand nets. The coefficients of allometry and proportionality were within the ranges estimated for fishes. All three species exhibited coefficients of allometry (b) higher than 3 in the LWR.
