Evaluation of fish populations and relative abundance within Pools A, B and C of the Kissimmee River: Possible responses to the Pool B demonstration project

Channelization of the Kissimmee River from 1962 to 1971 altered the natural hydrology of the river/floodplain system. Results of construction of the C-38 canal included loss of continuous flow of water and loss of floodplain habitat which adversely impacted the fish community. In 1984 the South Florida Water Management District (SFWMD) constructed the Pool B demonstration project to evaluate the feasibility of a planned restoration project. To evaluate success of the demonstration project in enhancing the Pool B fish fauna, a hoop net sampling program was conducted in 1996. The data suggest that black crappie (Pomoxis nigromaculatus) and other sport species in Pool B are benefiting from habitat enhancements resulting from the demonstration project. Additional analysis distinguishes black crappie as the only centrarchid sampled that maintains activity during nocturnal hours. Bluegill (Lepomis macrochirus) were most active during May sampling when water temperatures were optimal for spawning.
