Dataset title: Standard Lengths and Mean Weights for Prey-base Fishes from Taylor River and Joe Bay Sites, Everglades National Park (FCE), South Florida from January 2000 to April 2004 Dataset ID: LT_CD_Lorenz_001 Research type: Long-Term Dataset Creator Name: Dr. Jerry Lorenz Position: Project Collaborator Organization: National Audubon Society Address: Tavernier Science Center, 115 Indian Mound Trail Tavernier, Florida 33070 USA Phone: (305) 852-5092 Email: jlorenz@audubon.org URL: http://www.audubonofflorida.org/science/tavernier.htm Metadata Provider Organization: Florida Coastal Everglades LTER Address: Florida International University 11200 SW 8th Street, OE 148 Miami, FL 33199 USA Phone: 305-348-6054 Email: fcelter@fiu.edu URL: https://fcelter.fiu.edu 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.

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.
