Recipes vary, but it often consists of ground fish, vegetables such as onion and carrots, and bread crumbs formed into loaves or balls.</p><p>The shortfall results partly from the bitterly cold winter that caused vast sections of the Great Lakes to freeze over. The ice cover kept some commercial fishing crews stuck in port. A drop in the whitefish population is also to blame.</p><p>Kevin Dean of Superior Fish Co. near Detroit says his latest shipment amounted to just 75 pounds, although he requested 500 pounds.</p><p> Tue, 15 Apr 2014 14:32:14 +0000 The Associated Press 17231 at http://michiganradio.org Whitefish shortage causing Passover meal problems The extensive ice cover could delay fish migrations in the Great Lakes http://michiganradio.org/post/extensive-ice-cover-could-delay-fish-migrations-great-lakes <p><span style="line-height: 1.5;">&nbsp;</span></p><p><span style="line-height: 1.5;">The prolonged winter and the ice cover on the Great Lakes could lead to some lasting effects on wildlife.</span></p><p><span style="line-height: 1.5;">For one thing, scientists expect that a lot of the fish that people like to catch will be showing up late to the places they usually spawn.</span></p><p><span style="line-height: 1.5;">Solomon David is a research scientist at Shedd Aquarium in Chicago.</span></p><p><span style="line-height: 1.5;">David basically chases fish around for a living.</span></p> Thu, 03 Apr 2014 16:40:47 +0000 Rebecca Williams 17088 at http://michiganradio.org The extensive ice cover could delay fish migrations in the Great Lakes Ohio explores return of sturgeon to Lake Erie http://michiganradio.org/post/ohio-explores-return-sturgeon-lake-erie <div>PORT CLINTON, Ohio (AP) - Ohio's wildlife agency is looking at bringing a prehistoric fish back to Lake Erie.</div><div>&nbsp;</div><div>The Ohio Department of Natural Resources is looking into whether it can reintroduce breeding populations of sturgeon to the lake.</div><div>&nbsp;</div><div><p><span style="line-height: 1.5;">Sturgeon were once plentiful but thought to be all but gone from Lake Erie less than two decades ago.</span></p> Sat, 01 Mar 2014 20:32:40 +0000 Associated Press 16674 at http://michiganradio.org Ohio explores return of sturgeon to Lake Erie Canadian trucking company slammed with $75,000 Asian carp fine http://michiganradio.org/post/canadian-trucking-company-slammed-75000-asian-carp-fine <p>A Canadian court has <a href="http://blogs.windsorstar.com/2014/01/16/75k-in-fines-levied-for-importing-live-asian-carp/">slammed a trucking company and one of its drivers</a> with a combined $75,000 fine for trying to haul live Asian carp across the U.S.-Canadian border.</p><p>Driver Yong-Sheng Zhang is with the Edmonton, Alberta-based Alltheway&nbsp;Trucking Inc.</p><p>Twice in early 2012, Zhang crossed the Ambassador Bridge connecting Detroit and Windsor, Ontario, with a truckload of fish from Arkansas.
