摘要：This work was developed in the Bacanga river basin, from April 2012 to February 2013, with six established collection points, with the aim of characterizing the environment and the ichthyoplankton community. Therefore, measurements were made of physical-chemical parameters of the water. Ichthyoplankton samples were collected in horizontal hauls with the aid of a plankton net conical-cylindrical mesh of 300 micrometers. Specific gravity was calculated for fish larvae and biotic and abiotic data were statistically interrelated. The eggs and larvae were present in all months of sampling. Fish larvae in the basin study showed a spatial pattern of marine influence, and the collection points near the mouth of the river are important environments used as spawning and early development, working as a nursery for some species of marine fish.
