More than 85 species of fish occur in the basin, and their populations can be abundant. The lifeblood of the fishery is the Atchafalaya Basin's annual flooding and dewatering cycle. Overflows occur during the winter and spring rains, with many areas gradually becoming dewatered during the summer and fall. Experienced anglers watch the water levels to decide when and where to fish. Largemouth bass, white crappie, black crappie, warmouth, bluegill, redear sunfish, and channel catfish are the primary species sought.
NOTE. There is a fish consumption advisory in Big Alabama Bayou, due to high mercury levels found in fish. Pregnant women and children are cautioned against eating fish caught in this area. For more information on fish consumption advisories refer to the Louisiana Department of Health's website for health advisories on fish consumption.
