| Notas | Occurs in quiet, clear pools and backwaters of lowland creeks, small to large rivers, oxbow lakes, swamps and sloughs (Ref. 10294). Occasionally enters brackish waters. Young feeds on mosquito larvae and microcrustacea for a short time, but rapidly becomes piscivore, feeding on Gambusia and Fundulatus spp., and then feeding almost exclusively on gizzard shad at larger sizes. Spawning was observed on dead vegetation and algal mats in quiet backwater areas (Ref. 10294). |
