Abstract: Cyprinids are susceptible to local, watershed, and regional extirpation within the United States. Habitat alterations, non-indigenous species introductions, changes in water quality, and anthropogenic barriers have resulted in a decrease in overall cyprinid biodiversity. The objectives of this study are (1) to establish baseline water quality characteristics among sites in summer and fall, 2016, (2) to compare minnow densities to percent macrophyte cover among trap sites for common species, and (3) to compare 2016 minnow densities by species and combined with 2014 and 2012 density estimates. Heron Marsh is a shallow marsh located with the Adirondack Park, NY, that supports a wide variety of fishes in the Cyprinidae family. Baseline water quality was collected using an YSI meter, cyprinid densities were estimated using galvanized steel minnow traps, and macrophyte cover data was estimated using a 21-point grid system for trap sites within the marsh. Water quality monitoring will help assess changes in the marsh over time due to global warming. More minnow trap sites must be established to determine if there is a relationship between macrophyte cover and cyprinid abundance. This will allow the statistical power of our tests to become robust to assumptions that were otherwise violated. Cyprinid biodiversity and abundance were highest amongst the upper region of the marsh for most years. This suggests that the upper region of the marsh may be a sanctuary or refuge for certain cyprinid species.
