The fish community of a small impoundment in upstate New York

Moe Pond is a dimictic impoundment with surface area of 15.6 ha, a mean dep th of 1.8 m, and an unexploited fish community of only two species: brown b ullhead (Ameiurus nebulosus) and golden shiner (Notemigonus crysoleucas). T he age-1 and older brown bullhead population was estimated to be 4,057 indi viduals, based on the Schnabel capture-recapture method of population estim ation. Density and biomass were respectively estimated at 260 individuals/h a and 13 kg/ha. Annual survival rate of age-2 through age-5 brown bullheads was estimated at 48%. The golden shiner length-frequency distribution was unimodal with modal length of 80 mm and maximum total length of 115 mm. The golden shiner population estimate was 7,154 individuals, based on seven be ach seine haul replicate samples; the density and biomass were 686 shiners/ ha and 5 kg/ha, respectively. This study provides an information baseline t hat may be useful in understanding food web interactions and whole-pond nut rient flux.
