    Description: This study investigated the status of fish communitiesin 12 naturally acid Florida lakes. The small, shallowlakes were located in the Ocala National Forest, the TrailRidge, and panhandle Florida; regions where lakes have lowacid neutralizing capacities and are considered sensitive tofurther acidification from anthropogenic sources.Fifteen species from seven families were capturedduring mark-recapture sampling. Warmouth (Lepomis gulosus)was the only cosmopolitan species in the study. Bluegill(Lepomis macrochirus) and largemouth bass (Micropterussalmoides), collected from 11 and 10 lakes, respectively,were also widely distributed species. Total fish abundanceand biomass were not related to lake pH or total alkalinity.(Document has 202 pages)

    Notes: Abstract I used replicated 37.8 1 aquaria in a factorial design (four densities of zebra mussel, Dreissena polymorpha; two hydrologic regimes) to determine if the survival or growth of juvenile fathead minnows (Pimephales promelas) was affected by the density of zebra mussel or by the retention time of the test system. None of the fathead minnows died during the 30-d experiment. However, growth of fathead minnows was lower (P〈0.05) at the highest (3000 m−2) than at the lowest density of mussels (0 m−2). Fish growth was not affected by water retention time or the interaction of water retention time and mussel density (P〉0.05). These laboratory results suggest that juvenile fish survival will not be affected by low to moderate densities of mussels (0–3000 m−2) but fish growth might be adversely affected at moderate densities of mussels (e.g., 3000 m−2).
