Zooplankton of the St. Clair-Detroit River System, 2012-2014 (ver. 1.2, February 2021)
January 20, 2021
Crustacean zooplankton were collected, enumerated, identified, and measured within the St. Clair-Detroit River System (SCDRS). Collections were made using a 0.5 m diameter 153 um zooplankton net. Nets were lowered to about 0.5 m from bottom depth and retrieved. Nets were utilized with a General Oceanics flowmeter to calculate the distance the net traveled. At sites of collection, both temperature (degrees C) and Secchi depth (m) were collected for abiotic influencing factors of the zooplankton community. Collected specimens were narcotized in sugar formalin. Specimens were enumerated, identified, and measured under a dissection microscope. Volumetric estimates (m^-3) were obtained by applying the distance traveled and the area of the net. Abundances and biomasses were estimated based on the average length of a group of organisms and the samples estimated to be within a collected sample, and then the average estimated weight of an individual from length-weight regressions.

Zooplankton dynamics in a Great Lakes connecting channel: Exploring the seasonal composition within the St. Clair-Detroit River System
The connecting channels linking the Laurentian Great Lakes provide important migration routes, spawning grounds, and nursery habitat for fish, but their role as conduits between lakes for zooplankton is less understood. To address this knowledge gap in the St. Clair–Detroit River System (SCDRS), a comprehensive survey of crustacean zooplankton was performed in both riverine and...
