An updated survey of freshwater fishes within Letchworth State Park and surrounding areas of the Genesee River

The goal of this study was to gather information about freshwater fishes in Letchworth State Park (42.615275°N, -77.992825°W), a portion of New York State-owned land located in the Genesee River watershed that lacks known data about its fish diversity. The fish collection took place between 2017 and 2019 in the Genesse River upstream and downstream of the falls using gill, hoop, and seine netting and electrofishing. This was the first attempt at a comprehensive survey of this portion of the river, which allowed for a baseline to be established regarding fish biodiversity in the region. The updated total number of species found in this portion of the Genesee River was 25, 22 of which were newly identified downstream of the falls, in Letchworth State Park. We encourage further collection and continuation of this survey with consistent sampling techniques to promote ongoing field surveys and fish collection that inform freshwater fish diversity in stream ecosystems across the globe., Fish were captured between 2017 and 2019 at 3 locations along the Genesee River in western New York; upstream of Letchworth State Park, downstream of the falls in Letchworth State Park, and downstream (outside) of Letchworth State Park. Out of 25 total species captured, 22 were first documented below the falls in Letchworth State Park. Fish were captured using hoop, gill, and seine nets as well as electroshocking. Fish images were photographed at the time of capture and identified using markings and published sources and NYSDEC personnel for identification. The first Table (Table 2 in the manuscript) is a list of species captured, year of capture, site of capture (see Figure 1 in the manuscript for map), and whether it was novel to site B, which is the site below the falls in Letchworth State Park. Novelty to site B was based on Carlson & Daniels Atlas, if the fish hadn't been identified at this site already, it was denoted as 'novel' with a 'Y'.

Order of columns in Table 1: Fish species, Scientific name, year of capture, location of capture denoted as A, B, or C (see Figure 1 in manuscript for location of sites A, B, C), whether the fish captured at site B is novel to site B based on Carlson and Daniels 2016 Atlas of Inland Fishes of New York (identified with 'Y').

Order of columns in Appendix 1: Fish species, Scientific names, previously captured in the Genesee Watershed (identified with 'X'), previously captured in Genesee River (identified with 'X')

Any cells that are filled with 'N/A' represent a lack of fish capture in that year for that species (Table 1), that fish were not novel to site B (Table 1), or that fish species were not surveyed in the Genesee Watershed or Genesee River (Appendix 1).
