These data contain morphometric measurements collected on the left side of Cisco (Coregonus artedi) collected from Lake Ontario in 2018. Measurements were obtained by two methods, first by direct measurements made on the thawed specimens using a hand caliper by one person, then using a digital image technique. The digital image measurements were completed by two different measurers to evaluate how reproducible measurements extracted from digital images were between the two measurers.

Population decline in the federally endangered June sucker (Chasmistes liorus), a lakesucker unique to Utah Lake, Utah, has been attributed in part to hybridization with the more widespread Utah sucker (Catostomus ardens). As a group, suckers in Utah Lake exhibit considerable external morphological variation. Meristic and morphological ambiguities, presumably the result of hybridization, create a continuum of intermediate forms between Chasmistes and Catostomus extremes and prevent definitive identification to species. Here we describe and evaluate the morphological and genetic variation in suckers in Utah Lake by comparing a morphological analysis with amplified fragment length polymorphism and microsatellite analyses....
