Science: Alewife impacts on native Great Lakes fishes

Alewives Alosa pseudoharengus, native to the Atlantic Ocean, invaded Lake Ontario via the Erie Canal in the 1860’s, then Lake Erie (1930’s), Lake Huron (1933), Lake Michigan (1949) and Lake Superior (1954).  Lake trout Salvelinus namaycush and burbot Lota lota predation contained alewife population growth.  Eventually sea lamprey predation reduced abundances of these predators, allowing alewives to proliferate.  From the 1960’s to the early 90’s, sea lamprey control and fish stocking programs allowed salmon stocks to grow and this reduced alewife populations.  Madenjian et al. (2008) examined commercial catch records, fish abundances from fishery-independent surveys and other literature to determine the effects of alewives on native fish populations in the Great Lakes.  Trends in fish abundance were compared across lakes. Lake Superior served as a baseline because alewife abundance is extremely low due to the low temperatures of the lake.  Lake Erie was not included in this study because the alewife population has a low rate of survival through the winter.

Science: Cormorant feeding on yellow perch

            Yellow perch Perca flavescens are abundant in Dore Lake, Saskatchewan, but do not achieve sizes acceptable to anglers (total length approximately 10 inches).  Numbers of double-crested cormorant Phalacrocorax auritus, a piscivorous bird, have increased from 70 breeding pairs on Dore Lake in the 1960’s to 11,513 breeding pairs in 2006 and they consume 1.4-1.7 million kg of fish per year.  Barks et al. (2010) examined growth rates, timing of ontogenetic diet shifts and cormorant predation of yellow perch on Dore Lake to determine if they explained the lack of acceptable yellow perch.

This week in recent fishing history


In Port Washington, usually light effort from the ramp and light to moderate effort from shore.  The actions has been slow for boats but the action is usually exceptional from shore.  Fish Days in Port Washington is this weekend, expect the ramps to be closed temporarily. In Sheboygan, usually moderate effort from the ramp and moderate to strong effort from the piers. The action has usually been slow from the boats but there has been exceptional action from the piers.
