Morphology data for Ciscoes (Coregonus, subgenus Leucichthys) collected in the Great Lakes Cisco Project
This dataset contains morphological information for Ciscoes (Coregonus, subgenus Leucichthys) collected from the Great Lakes as part of the "Great Lakes Cisco Project". The project was initiated in 1950 by Stanford H. Smith, who was a Fishery Research Biologist in the then U.S. Bureau of Commercial Fisheries. The dataset includes 16 morphometrics (linear measurements) and one meristic (count of gill rakers) for Ciscoes, together with biological data (i.e., length, weight, sex, and maturity), sampling location, and date of collection. Consult Koelz (1929) and the "Morphology of Ciscoes" section in Eshenroder et al. (2016) for descriptions of how measurements and counts were made in the then "Ann Arbor Laboratory" of U.S. Bureau of Commercial Fisheries. References Eshenroder, R. L., P. Vecsei, N. E. Mandrak, D.

Morphometric measurements of Cisco (Coregonus artedi) from Lake Ontario 2018
공공데이터포털
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.

Traditional and geometric morphometric data describing wild and artificially reared cisco (Coregonus artedi) from lakes Huron and Ontario
공공데이터포털
These data describe morphometric (body shape) measurements of wild and artificially reared (i.e., raised in a laboratory or fish hatchery) cisco (Coregonus artedi) from lakes Huron and Ontario in the Laurentian Great Lakes. Specifically, this data release includes traditional morphometric data (i.e., measurements of fish specimens) describing wild and artificially reared cisco from Lake Huron, as well as geometric morphometric data (i.e., landmarks placed on images of fish) describing cisco head shapes for wild and artificially reared cisco from both lakes Huron and Ontario. Artificially reared individuals from Lake Huron were raised at the U.S. Geological Survey Great Lakes Science Center in Ann Arbor, MI, USA, and one family of offspring were split among three rearing temperature treatments. Artificially reared individuals from Lake Ontario were raised at the Tunison Laboratory of Aquatic Science in Cortland, NY, USA. These data were collected by the authors on this data release from 2017-2023 and used to analyze the impacts of artificial rearing on cisco body shapes, with a focus on head shapes.

Demographic, morphometric, and meristic data describing cisco (Coregonus artedi) captured in the Spanish River, Ontario, Canada, 15-16 November 2022
공공데이터포털
These data describe demographic (e.g, age), morphometric (body shape), and meristic (total number of gill rakers) measurements of a probable spawning run of cisco (Coregonus artedi) collected from the Spanish River (Ontario, Canada) immediately downstream of the Espanola Dam from 15-16 November 2022. These data were used to provide baseline biological, demographic, and morphological information on this population.
Historical Spawning Sites for Lake Whitefish (Coregonus clupeaformis) and Cisco (Coregonus artedi) in Lake Erie and Connecting Channels, 1850-1960 (ver. 2.0, July 2022)
공공데이터포털
This data contains coordinate locations for suspected historical spawning locations of lake whitefish (Coregonus clupeaformis) and cisco (Coregonus artedi) across the Lake Erie basin, including the Detroit River, Lake St. Clair, and the St. Clair River. Data points were summarized using ArcGIS 10.5. Data came from published and unpublished sources cited in the Atlas of the Spawning and Nursery Areas of Great Lakes Fishes (Goodyear et al. 1982) and other sources as described. Data points included were specific locations described as having the presence of eggs or spawning fish. Pseudo-absence data used for comparison purposes are also provided in this data release.

Great Lakes-Wide Dataset of Historical Coregonine Stocking Events
공공데이터포털
This dataset is the result of coordinated efforts to compile data associated with stocking events for whitefishes and ciscoes (members of the Coregoninae subfamily) of Great Lakes origin. The dataset includes more than 4,700 records associated with coregonine stocking, from over 150 information sources, spanning the years 1870 - 2022. The compiled information includes species, quantities, dates, source location, and stocked location when present. Records were georeferenced using evidence from the original sources and were quality checked in ArcGIS Pro (datum: WGS84) to ensure concordance between coordinates and cited locations.
Historical Spawning Sites for Lake Whitefish (Coregonus clupeaformis) and Cisco (Coregonus artedi) in Lake Ontario and Connecting Channels, 1860-1970
공공데이터포털
The following data release contains coordinates for suspected historical spawning locations of lake whitefish (Coregonus clupeaformis) and cisco (Coregonus artedi) across the Lake Ontario basin, including the Niagara River and St. Lawrence River. These data were gathered from published and unpublished sources cited in the Atlas of the Spawning and Nursery Areas of Great Lakes Fishes (Goodyear et al. 1982) and other sources as described. We define "spawning locations" as areas having eggs or spawning fish present. When available the data also contain substrate and depth information. Pseudo-absence data used for comparison purposes are also provided in this data release. Data points were summarized using ArcGIS 10.5
