Length-weight relationships for freshwater fish species from humid forest enclaves at the Brazilian semiarid

Abstract

We report the length-weight relationships (LWR) for 11 fish species inhabiting headwater streams in the Araripe and Ibiapaba plateaus, Brazilian semiarid. Values of r2, a and b ranged respectively from.953 to.998, 0.010 to 0.043 and 2.81 to 3.69. Our reports on LWR are pioneer in humid forest enclaves at the Caatinga biome. Such enclaves of forest can be a checkpoint to climate change, but are under strong human pressure and remain under low investigation. © 2017 Blackwell Verlag GmbH.
