Lake whitefish (Coregonus clupeaformis) status data created for the Western Division of the American Fisheries Society (WDAFS)
thumbnail
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 Data came from published and unpublished sources cited in the Atlas of the Spawning and Nursery Areas of Great Lakes Fishes (Goodyear et al. 1982) and other sources as described.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. First release: 2019 Revised: July 2022 (ver. 2.0)

A long-term, multiseason, fish egg sampling program is conducted annually on the Detroit, Saint Clair, and Saint Marys rivers to identify where productive fish spawning habitat currently exists and evaluate habitat restoration projects. Egg mats were placed on the river bottom during the spring and fall at historic spawning areas, candidate fish spawning habitat restoration sites, and completed spawning habitat restoration sites throughout the rivers. Widespread evidence was found of lithophilic spawning by numerous native fish species, including walleye (Sander vitreus), lake whitefish (Coregonus clupeaformis), lake sturgeon (Acipenser fulvescens), suckers (Family: Catostomidae), and trout-perch (Percopsis omiscomaycus)....

To investigate the contemporary distribution of lake whitefish spawning and over-winter egg survival within western Lake Erie, potential spawning locations were sampled for eggs from 2016 to 2018. Eggs were collected using a 39-kg iron sled attached to a diaphragm pump towed for 2 - 5 minutes. The data describe the number, date of collection, and exact collection location of Lake Whitefish fish eggs collected in the western basin of Lake Erie from 2016-2018.

These data include a field study of the sediment hardness and fish egg density (walleye [Sander vitreus] and lake whitefish [Coregonus clupeaformis]) after sediment cleaning treatments (propulsion sled or hydro-jet sled) conducted at two reef locations in Saginaw Bay, Lake Huron, during 2018 and 2019. The data includes the year, species, reef, treatment type (jet, fan, control), number of eggs, and egg density in the treatment area. Relative sediment hardness for the treatment areas assessed before and after sediment cleaning experiments is provided. Additionally, walleye eggs were collected from Brookville Reservoir, Indiana, and incubated at the aquaculture research laboratory at Purdue University (West Lafayette,...
Egg mat retention trials were conducted with walleye (Stizostedion vitreum) and lake whitefish (Coregonus clupeaformis) eggs in an experimental flume tank, seeded directly on egg mats (test retention efficiency) and hand dispersed in flowing flume water to simulate spawning over egg mats (test capture efficiency) with and without alternate substrate. In the field study, we measured number of eggs collected on mats and with bottom drift nets in the Detroit River to compare capture effectiveness. The field collection data describe the number, date of collection, and exact collection location of target species (walleye and lake whitefish). The flume trial data include number of eggs retained or collected, water velocity,...

This dataset contains data collected on various vessel operations on the Great Lakes and their connecting channels, primarily the St. Clair River, Lake St. Clair, Detroit River, and western Lake Erie, although other locations have been sampled and included in this dataset. This dataset contains the field variables, environmental conditions, larval catches (numbers), larval fish identifications, and associated auxiliary information with the sampling locations.
