Population synchrony of a native fish across three Laurentian Great Lakes: Evaluating the effects of dispersal and climate Population synchrony of a native fish across three Laurentian Great Lakes: Evaluating the effects of dispersal and climate
Climate and dispersal are the two most commonly cited mechanisms to explain spatial synchrony among time series of animal populations, and climate is typically most important for fishes. Using data from 1978-2006, we quantified the spatial synchrony in recruitment and population catch-per-unit-effort (CPUE) for bloater (Coregonus hoyi) populations across lakes Superior, Michigan, and...

Long-term trends in habitat use of offshore demersal fishes in western Lake Huron suggest large-scale ecosystem change Long-term trends in habitat use of offshore demersal fishes in western Lake Huron suggest large-scale ecosystem change
We estimated mean depths of capture for offshore demersal fish species, grouped into three habitat-based guilds (shallow benthic, pelagic, and deep benthic), using fall bottom trawl data (27–73 m) in the western main basin of Lake Huron from 1976 to 2007. The mean depth of capture of the shallow and deep benthic guilds initially exhibited a trend toward capture in shallower water...

Status and trends of prey fish populations in Lake Michigan, 2008 Status and trends of prey fish populations in Lake Michigan, 2008
The Great Lakes Science Center (GLSC) has conducted lake-wide surveys of the fish community in Lake Michigan each fall since 1973 using standard 12-m bottom trawls towed along contour at depths of 9 to 110 m at each of seven index transects. The resulting data on relative abundance, size structure, and condition of individual fishes are used to estimate various population parameters that...

Expansion of Dreissena into offshore waters of Lake Michigan and potential impacts on fish populations Expansion of Dreissena into offshore waters of Lake Michigan and potential impacts on fish populations
Lake Michigan was invaded by zebra mussels (Dreissena polymorpha) in the late 1980s and then followed by quagga mussels (D. bugensis) around 1997. Through 2000, both species (herein Dreissena) were largely restricted to depths less than 50??m. Herein, we provide results of an annual lake-wide bottom trawl survey in Lake Michigan that reveal the relative biomass and depth distribution of...

Change in diel catchability of young-of-year yellow perch associated with establishment of dreissenid mussels Change in diel catchability of young-of-year yellow perch associated with establishment of dreissenid mussels
1. Non-native mussels have increased water clarity in many lakes and streams in North America and Europe. Diel variation in catchability of some fish species has been linked to visibility during survey trawls (used to measure escapement). 2. Water clarity increased in nearshore areas of western Lake Erie by the early 1990s, following passage of legislation in 1972 to improve water...

Comparisons between consumption estimates from bioenergetics simulations and field measurements for walleyes from Oneida Lake, New York Comparisons between consumption estimates from bioenergetics simulations and field measurements for walleyes from Oneida Lake, New York
Daily consumption was estimated from the stomach contents of walleyes Sander vitreus collected weekly from Oneida Lake, New York, during June-October 1975, 1992, 1993, and 1994 for one to four age-groups per year. Field rations were highly variable between weeks, and trends in ration size varied both seasonally and annually. The coefficient of variation for weekly field rations within...
