Summary

These data consist of larval fish and water profile data collected with a nearshore to offshore transect approach at 9 transects throughout Lake Huron. Larval fish and their stomach contents were identified, enumerated, and measured (if possible) using a dissecting microscope. These data were used to calculate densities of potential fish prey items (what is available in the environment) and compare that to what the fishes ate for selectivity analysis. Larval fish age estimation based on daily growth rings from otoliths was also conducted. These data are in raw form. The water profile data were collected using a bathythermograph and bin-averaged at the 1 m level. Environmental prey data are available at the following address: https://doi.org/10.5066/p9bnqppm.

Purpose

These data were collected by the U.S. Geological Survey (USGS) Great Lakes Science Center (GLSC) as part of a collaborative effort for the Environmental Protection Agency's (EPA) Cooperative Science and Monitoring Initiative (CSMI). This effort intensively samples one of the Great Lakes every five years. The type of samples collected depends on the science priorities at that time, but it usually involves a food web component. During 2017, Lake Huron was intensively sampled. These data are intended for use by Lake Huron fisheries managers, academia, the fishing industry, and the public. Data can be used to calculate diet proportion of larval fishes, among other calculations.
