Summary
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 ~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. [...]

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.

These specimens were collected to determine the overall complexity of crustacean zooplankton with the SCDRS. Estimates are useful in the determination of future works as an available baseline for either zooplankton dynamics or diet selectivity by fishes.
