Long-term Fish Population Trends
in Florida Lakes: 2003 Data

We thank everyone who helped continue the Florida LAKEWATCH long-term fish monitoring program, especially personnel from the Florida Fish and Wildlife Conservation Commission and the University of Florida Department of Fisheries and Aquatic Sciences. The fifth year was successful collecting data on 32 Florida LAKEWATCH lakes (Table 1). This report contains a summary of both the electrofishing (27 water bodies) and trawl (8 water bodies) sampling conducted from 1998 -2003. The report also includes the following data that have been collected for Florida LAKEWATCH or for other research projects:

1 . Florida LAKEWATCH water chemistry data:

a. Location of water body (Latitude and Longitude),
b. Period of record of sampling,
c. Surface area (Dickinson at al. 1982, Shafer at ad. 1986, or Florida LAKEWATCH)
d. Florida Lake Region (Griffin at al. 1997).
e. Geologic and physiographic regions (Brooks 1981),
f. Supplemental water chemistry data: pH, total alkalinity, conductance, color, chloride, iron, silicon, sulfate, calcium, magnesium, sodium, and potassium.
g. Long-term and monthly Florida LAKEWATCH averages for total phosphorus, total nitrogen, chlorophyll, and Secchi depth.

2. Florida LAKEWATCH aquatic plant survey data:

a. Percent Area Covered by macrophytes (PAC),
b. Percent Volume Inhabited with aquatic macrophytes (PVI),
c. Above-ground standing crop of emergent, floating-leafed, and submerged vegetation (kg /M 2),
d. Average width (m) of the floating-leafed and emergent zones,
e. Average lake depth (m), and
f. A list of all plant species found according to the frequency in which they occurred.

The fish data in this report are summary data and are compared with data collected from 60 Florida lakes (Canfield and Hoyer 1992) ranging in trophic status and aquatic macrophyte abundance. This was done to allow citizens and professional to examine the data in relation to a range of other Florida lakes. While this report only presents summary data, the raw data, including information on fish sizes, are available on request. To obtain a copy of these data contact the Florida LAKEWATCH office
