  • Dataset Abstract
    This study examines temporal and spatial dynamics in the fish community of the oligohaline to mesohaline reaches of ecotonal creeks along the southwest region of Everglades National Park. Collections of fish in SW ENP during 2004 - 2014 across Rookery Branch and Tarpon Bay. Sampling started in the wet season of 2004, and has been conducted three times per year at these approximate times: November (wet season); February (transition); and April (dry season). Electrofishing samples were processed in the field, and all species (except for non-natives) were returned live at the point of collection. In the Rookery Branch region, fish abundance varies markedly yearly and seasonally. Catches peak in the drier months, reflecting a pulse of movement by freshwater taxa into creeks as marshes upstream dry. The timing of this pulse is closely tied to the pattern of water recession in upstream marshes, and has important ramifications for wading bird prey availability.

  • Methods
    Sampling Description
    Sampling is conducted at 15 mangrove creeks in two drainages: Rookery Branch and the North, Roberts, and Watson rivers. Electrofishing is used to target large-bodied predatory species. At each creek, we systematically sample, three 100 meter long sections of creek bank by electrofishing (0-100m, 200-300m, and 400-500m). Each electrofishing bout lasts five minutes (pedal time). Electrofishing is an effective method for sampling large fishes in freshwater habitats, and eletrofishing catch per unit effort (CPUE) provides a reliable index of fish abundance. For all bouts, electrofishing power is standardized to 1500 watts according to the ambient temperature and conductivity conditions. Because creek width is considerably greater than the electric field generated by the electrofisher, a left or right bank was randomly selected for each bout. Folling USGS-NAWQA guidelines, all electrofishing is conducted using intermittent application of electrical current to prevent fish from fleeing deep beneath the mangroves. All fish captured are placed in a holding tank, identified, measured (to the nearest 1-mm standard or total length), weighed (if necessary), and released after full recovery. Only non-indigenous species are saved and preserved in 10 percent formalin to be returned to the laboratory for processing. During each sampling event, we use a YSI 85 unit to record physico-chemical parameters (water temperature, specific conductance/salinity, and dissolved oxygen) at the beginning of each electrofishing bout. Water clarity and bottom type are measured with a measuring stick and turbidity with an electronic turbidity meter.

    Abstract
    Sampling is conducted at 15 mangrove creeks in two drainages: Rookery Branch and the North, Roberts, and Watson rivers. Electrofishing is used to target large-bodied predatory species. At each creek, we systematically sample, three 100 meter long sections of creek bank by electrofishing (0-100m, 200-300m, and 400-500m). Each electrofishing bout lasts five minutes (pedal time). Electrofishing is an effective method for sampling large fishes in freshwater habitats, and eletrofishing catch per unit effort (CPUE) provides a reliable index of fish abundance. For all bouts, electrofishing power is standardized to 1500 watts according to the ambient temperature and conductivity conditions. Because creek width is considerably greater than the electric field generated by the electrofisher, a left or right bank was randomly selected for each bout. Folling USGS-NAWQA guidelines, all electrofishing is conducted using intermittent application of electrical current to prevent fish from fleeing deep beneath the mangroves. All fish captured are placed in a holding tank, identified, measured (to the nearest 1-mm standard or total length), weighed (if necessary), and released after full recovery. We measure mass of those species for wich we do not have reliable length-mass regression equations with which to estimate mass-this procedure results in less handling of fishes and reduces stress on the specimens. Only non-indigenous species are saved and preserved in 10 percent formalin to be returned to the laboratory for processing. Although electrofishing typically targets large fish species, we routinely capture specimens as small as 5-cm standard length (SL). During each sampling event, we use a YSI 85 unit to record physico-chemical parameters (water temperature, specific conductance/salinity, and dissolved oxygen) at the beginning of each electrofishing bout. Water clarity and bottom type are measured with a measuring stick and turbidity with an electronic turbidity meter.

    Quality Control
    All data from sampling, catch, and processing datasheets are entered in spreadsheet format using Microsoft Excel. Separate files are created and managed for two sampling methods (electrofishing and minnow trapping). Since analyses are multiyear, all years of data are combined into a single file, and as new data is gathered, it is added to a master datafile containing all previous years of data. Post data entry, data are verified and validated by a different technician from the technician that entered the data. Then, the data files are cleaned and formatted for statistical analyses.
