  • Dataset Abstract
    Prey-base fishes. The small demersal fishes of the coastal wetlands are a keystone element in this ecosystem. They are the primary and secondary consumers of the plants mentioned above and they are the primary food resource for myriad piscine (e.g. game species of fish), reptilian (e.g. juvenile crocodiles) and avian (e.g. wading birds) predators. The community dynamics of these fishes are dictated by hydrologic and hydrographic parameters so they also respond predictably to water management practices. Because they are a bottle-neck in the food web, their abundance and availability dictate the success of higher trophic levels. Fish are sampled in June, September and monthly from November through April at five locations. A 9m2 drop trap designed specifically for this habitat are used to quantify fish use. Nine traps are used at each site.

  • Methods
    Sampling Description
    Samples collected in June, Sep, and monthly from Nov-Apr. 9 traps collected per sample at each of two sites

    Method Step

    Description
    A 9 m2 drop net and removable walkways designed to quantify densities of small fishes in wetland habitats with low to moderate vegetation density. The method permits the collection of small, quantitative, discrete samples in ecologically sensitive areas by combining rapid net deployment from fixed sites with the carefully contained use of the fish toxicant rotenone. This method requires very little contact with the substrate, causes minimal alteration to the habitat being sampled, samples small fishes in an unbiased manner, and allows for differential sampling of microhabitats within a wetland. When used in dwarf red mangrove (Rhizophora mangle) habitat in southern Everglades National Park and adjacent areas (September 1990 to March 1993), high recovery efficiencies were achieved (78-90percent) for five common species less than 110 mm in length. About 20,000 individuals of 26 species were captured. The most abundant fishes were sheepshead minnow Cyprinodon variegatus, goldspotted killifish Floridichthys carpio, rainwater killifish Lucania parva, sailfin molly Poecilia latipinna, and the exotic Mayan cichlid Cichlasoma urophthalmus. The 9 m2 drop net and associated removable walkways are versatile and can be used in a variety of wetland types, including both interior and coastal wetlands with either herbaceous or woody vegetation. Specimens were returned to the lab for identification and measuring weight and length.
