Summary

Diet and estimated ages of Silver Chub (Macrhybopsis storeriana) collected by the US Geological Survey in western Lake Erie in 2014 are presented. Fish were frozen in the field at -20 C and dissected in the lab. Ages were estimated by one experienced biologist who estimated ages twice, then reconciled age estimates when the two age estimates differed. Diet taxa were enumerated, dried individually at 60 F until stable weight was achieved (~24-48 hrs), then weighed. Zero weights for non-zero counts indicates dry weight was below detection limit of the scale used.

Purpose

Silver Chub were collected during routine sampling and during additional sampling conducted as part of the Coordinated Science Monitoring Initiative (CSMI). The CSMI program is a Great-Lakes-Wide program that collects identical data on all 5 of the Laurentian Great Lakes on a 5-year rotation. Silver Chub in Lake Erie are considered critically imperiled in Michigan and endangered in Ontario, hence interest in Silver Chub is to understand their biology to promote recovery.
