Availability of dark daytime refuge may limit mysid abundance in the Laurentian Great Lakes Availability of dark daytime refuge may limit mysid abundance in the Laurentian Great Lakes
The zooplankton Mysis diluviana is a major component of the Laurentian Great Lakes food web and has recently declined in abundance in both lakes Michigan and Huron. Drivers of these declines are not well understood. Here, we explore the hypothesis that recent increases in water clarity have contributed to the decline of M. diluviana (mysids) by limiting the availability of daytime dark...
On the importance of ichthyoplankton monitoring for invasive grass carp control in the Laurentian Great Lakes On the importance of ichthyoplankton monitoring for invasive grass carp control in the Laurentian Great Lakes
Grass carp (Ctenopharyngodon idella) is an invasive herbivore observed in small numbers in the Laurentian Great Lakes since the 1980 s with records from all lakes except Lake Superior. Identification of diploid, age-1 + grass carp from the Sandusky River, a Lake Erie tributary, in 2012, prompted targeted efforts to evaluate the status of grass carp reproduction in the Lake Erie Basin. In...
Status and trends of pelagic and benthic prey fish populations in Lake Michigan, 2025 Status and trends of pelagic and benthic prey fish populations in Lake Michigan, 2025
Fall bottom trawl (fall BT) and lakewide acoustic (AC) surveys are conducted annually to generate indices of pelagic and benthic prey fish densities in Lake Michigan. The fall BT survey has been conducted each fall since 1973 using 12-m trawls at depths ranging from 9 to 110 m at fixed locations distributed across seven transects; this survey estimates densities of seven prey fish...
