The Adirondacks are a mountainous region in upstate New York. The Adirondack lakes were surveyed 1995- 2006 Research includes:- fish assemblage- population characteristics- relative abundance and composition- water chemistry
18 lakes were surveyed. The lakes range in elevation from 397 – 645 m and in size from 3.6-187 ha. Most lakes are shallow, ranging in depth from 1.5 – 13 m. All lakes were drainage lakes.
Fish were caught in two types of nets. Fish were marked, measured and released back to the lakes. Resurvey was carried out to identify, count and record each fish. Fish were caught again to examine the multiplicity and biological diversity.
Twenty-four species and two hybrids were present in the eighteen Adirondack lakes. The most abundant species were golden shiner and pumpkinseed. The rarest fish were yellow perch and brown bullhead. White sucker, pumpkinseed and rock bass, composed over 80% of the catch in most years.
Population of exotic taxa exceeded the presence of native species. The relationship between water chemistry and fish composition is unclear. The results in the survey can be used to compare conditions in other lakes in the region.
