Diurnal stream habitat use of juvenile Atlantic salmon, brown trout and rainbow trout in winter Diurnal stream habitat use of juvenile Atlantic salmon, brown trout and rainbow trout in winter
The diurnal winter habitat of three species of juvenile salmonids was examined in a tributary of Skaneateles Lake, NY to compare habitat differences among species and to determine if species/age classes were selecting specific habitats. A total of 792 observations were made on the depth, velocity, substrate and cover (amount and type) used by sympatric subyearling Atlantic salmon...

Influence of diet of double-crested cormorants on thiamine, lead, and mineral contents of their eggs Influence of diet of double-crested cormorants on thiamine, lead, and mineral contents of their eggs
Throughout much of the Great Lakes basin, reproduction of several fish species is impaired by deficiency of thiamine in their eggs, an effect attributed to consumption of thiaminase-containing forage species, primarily alewife (Alosa pseudoharengus.) Because the double-crested cormorant (Phalacrocorax auritus) nesting on islands in Lake Ontario is known to consume considerable amounts of...

Diel diet composition and feeding activity of round goby in the nearshore region of Lake Ontario Diel diet composition and feeding activity of round goby in the nearshore region of Lake Ontario
Expansion of the invasive round goby Apollonia melanostoma (=Neogobius melanostomus) throughout the Great Lakes drainage has created considerable concern among fisheries management agencies. These concerns have led to several studies on the biology and impact of the goby in the basin. However, little information exists on diel patterns in food consumption of the round goby. We examined...

Double-crested cormorant studies at Little Galloo Island, Lake Ontario in 2008: Diet composition, fish consumption and the efficacy of management activities in reducing fish predation Double-crested cormorant studies at Little Galloo Island, Lake Ontario in 2008: Diet composition, fish consumption and the efficacy of management activities in reducing fish predation
For almost two decades Little Galloo Island (LGI)has supported the largest colony of double-crested cormorants (Phalacrocorax auritus) in the eastern basin of Lake Ontario. Cormorant nest counts on the island since the early 1990's have averaged about 5,000 per year reaching a high of 8,400 in 1996. Johnson et al. (2008) estimate that cormorants from LGI alone have consumed 400 million...

Seasonal habitat use of brook trout and juvenile Atlantic Salmon in a Tributary of Lake Ontario Seasonal habitat use of brook trout and juvenile Atlantic Salmon in a Tributary of Lake Ontario
The seasonal habitat use of Salvelinus fontinalis (Brook Trout) and sub-yearling Salmo salar (Atlantic Salmon) was examined in Hart Brook, a tributary of Lake Ontario. Fish habitat use and available habitat were examined during summer and autumn. Interspecific differences in habitat use occurred as well as intraspecific seasonal differences. Overyearling Brook Trout were more selective...

Diet composition and feeding periodicity of wild and hatchery subyearling Chinook salmon in Lake Ontario Diet composition and feeding periodicity of wild and hatchery subyearling Chinook salmon in Lake Ontario
Diel feeding periodicity, daily ration, and diet composition of wild and hatchery subyearling Chinook salmon Oncorhynchus tshawytscha were examined in Lake Ontario and the Salmon River, New York. The diet of wild riverine salmon was composed mainly of aquatic invertebrates (63.4%), mostly ephemeropterans (25.8%), chiromomids (15.8%), and trichopterans (8.3%). The diet of riverine Chinook...
