					Also collected by using fish corrals. Inhabits fresh and brackish waters (Ref. 77016).  Generally estuarine; prefers areas faced by more oceanic waters.  They prefer slow-moving or almost stagnant bodies of water.  Species can be found up to 20 km from the sea in completely fresh water.  Large or ovigerous specimens can be found in intertidal areas, frequently associated with floating clumps of brown algae, Sargassum spp. (Ref. 343).
