Current Research
Hatching duration, growth and survival of age-0 largemouth bass along a latitudinal gradient of Florida lakes
    Florida’s spans over 7º of latitude and climates vary from sub-tropical in south Florida to temperate in north Florida.  Survival of age-0 largemouth bass to age-1 is largely influenced by temperature dependent factors such as: hatching time, growth rate, and over-winter mortality.  Thus, the influence of temperature driven factors affecting survival may differ across Florida’s latitudinal gradient. 

    We will evaluate factors affecting age-0 largemouth bass survival across Florida’s latitudinal gradient by sampling lakes in south, central and north Florida.  We will use block-net rotenone and electrofishing sampling to collect age-0 largemouth bass throughout the year.  We will quantify hatching date, growth, and diet contents, and conduct lipid analyses to characterize each lake to increase our understanding of mechanisms influencing survival differences across Florida.
