Here, we report on four years of intensive crayfish surveys in the southwestern portion of the Lake Michigan Basin, a region with diverse freshwater ecosystems and few previous records of crayfish distribution. From 2015 to 2018, baited minnow traps and SCUBA were used to document the distribution...
Zebra mussel [Dreissena polymorpha (Pallas)] colonization of rusty crayfish [Orconectes rusticus (Girard)] in Green Bay, Lake Michigan In August 1995 six rusty crayfish (Orconectes rusticus) colonized with zebra mussels (Dreissena polymorpha) were captured in small-meshed fyke-nets set as ... J...
We report and describe for the first time the presence, distribution and genetic diversity of the crayfish plague pathogen,A. astaci, in its potential center of origin, the southeastern US68. Previous studies regarding the origin, diversity, and distribution ofA. astacihave addressed different questi...

To minimize the ecological consequences, there is a need to manage the expansion ofP. clarkii. It has been reported that it can disperse terrestrially between adjacent, or nearly adjacent, environments19. However, without human assistance, it will not invade such large areas in China. The commod...
A JEWEL IN LAKE MICHIGAN CRAYFISH, CAMPFIRES, KIDS ON AN ISLANDKimberly Blanton, Globe Staff
Non-native rusty crayfish are abundant egg predators on spawning reef habitats for lake trout and coregonines in northern Lake Michigan. To better understand rusty crayfish life-history on these unique habitats, we conducted monitoring in 2012 and 2013 at four locations previously identified as ...
While 2-yr production was highest (59 kg/ha) in the lake stocked at the highest density and lowest (17 kg/ha) in one stocked at the lowest density, the former was achieved at the cost of a very slow growing trout population. Most of the crayfish production is not utilized as trout ...
Suppression of rusty crayfish on spawning reefs to protect fall spawning native fishes in the Great Lakes is hampered by regular storm events and ambient weather conditions, limiting the number of practical days traps can be checked, cleared, and re-baited. The Gee minnow trap design is the ...
