Total thiamine concentrations in lake trout Salvelinus namaycush eggs in lakes Huron and Michigan, 1996-2018

Monitoring of vitamin B1 (thiamine) in the eggs of lake trout (Salvelinus namaycush) collected from lakes Huron and Michigan has been conducted by the U.S. Geological Survey since the mid-1990’s. The results of this monitoring effort have been used by natural resource management agencies and native American tribes within the Great Lakes basin to evaluate the reproductive health of lake trout. The data in this release are the thiamine concentrations measured in lake trout collected from 1996-2018. Results are reported as total thiamine (nmol/g-egg), collection site, lake, year collected, and reference to the analysis methods.

Fisheries-dependent data for Cisco in Green Bay of Lake Michigan and Saginaw Bay of Lake Huron between 1929 and 1970

This data release presents part of historical fisheries-dependent data for Cisco (Coregonus artedi) in Green Bay of Lake Michigan and Saginaw Bay of Lake Huron collected by scientists from U.S. Geological Survey's Great Lakes Science Center, including three tables for monthly Cisco-catch and fishing-effort data and two tables for biological data of Cisco individuals. The monthly Cisco-catch and fishing-effort data tables are for small-mesh gill-net fisheries in Green Bay and Saginaw Bay (GBSB_GN.csv), pound-net fisheries in Green Bay and Saginaw Bay (GBSB_PD.csv), and shallow trap-net fishery in Saginaw Bay (SB_ST.csv) in the period 1929–1970. The biological data of Cisco individuals are from historical Saginaw...
