Survey data of larval fish, zooplankton, and aquatic plants collected from the St. Clair River delta, MI (2010-2011)

The St. Clair River delta, part of the St. Clair-Detroit River System (SCDRS), is the most fished coastal wetland area in the Laurentian Great Lakes and provides nursery habitat for a variety of fish species; however, few large-scale surveys of early fish life stages have been performed since the 1980s. Larval fish, zooplankton, and aquatic plants were sampled at 21 sites in delta channels and backwaters of the St. Clair-Detroit River System (SCDRS; USA/CAN) from May to July in 2010 and 2011 to characterize the habitats and resources used by larval fish in the delta. Larval fish were captured using conical nets and light traps, and diets from larval white sucker (Catostomus commersonii) were collected at three sites.
