TRAVERSE CITY, Mich. — A shortage of whitefish in the Great Lakes region resulting partly from the winter deep freeze is coming at an inconvenient time for Jewish families: the Passover holiday, when demand is high because it’s a key ingredient in a traditional recipe.

Markets in Chicago and Detroit were among those struggling to fill whitefish orders before the beginning of the eight-day celebration Monday evening, and a representative of a commercial fishing agency said the shortfall extended as far as New York.

“Everybody’s pulling their hair out,” said Kevin Dean, co-owner of Superior Fish Co., a wholesaler near Detroit whose latest shipment provided just 75 pounds of whitefish although he requested 500 pounds. “I’ve never seen it this bad this time of year.”

The dish that inspires such angst is gefilte fish, which somewhat resembles meat loaf or meatballs. Recipes handed down for generations vary but typically call for ground-up fish and other components such as onions, carrots, eggs and bread crumbs. Other fish such as cod, pike and trout are sometimes a part of the mix, but whitefish is especially popular.

“Just smelling that gefilte fish aroma tells my senses that it’s a Jewish holiday,” said Jason Miller, a rabbi and director of a kosher food certification agency in West Bloomfield, Mich.

In the Chicago suburb of Skokie, Ill., Ira Kirsche of Hungarian Kosher Foods said his market ordinarily would get 200 to 300 pounds of whitefish daily this time of year.

 

Gefilte fish (“gefilte” is a Yiddish word for “stuffed”) also is available frozen or in cans or jars. But for many, only homemade will do.

Elyse Fine of Rochester, N.Y., who travels to the Chicago area yearly to prepare Seder meals for extended family, said her family used jar varieties until about 10 years ago when her husband suggested she try producing it from scratch.

“Everybody loved it,” Fine said. “Now they don’t want me to go back to the jar stuff.”

She finally located some whitefish an hour’s drive away after coming up short at stores closer to home.

The whitefish shortfall is yet another ripple effect of the bitterly cold winter, which caused more than 90 percent of the Great Lakes surface area to freeze over. In some places, the ice cover was many feet thick, leaving commercial crews stuck in port.

“You have a lot of boats that can’t get out to fish, even now,” said Chuck Bronte, senior fishery biologist with the U.S. Fish and Wildlife Service in Green Bay, Wis.

Native American crews in northern Lake Michigan and Lake Huron, as well as Lake Superior, were able to drop their nets through holes drilled in the ice, said Mark Ebener, fishery assessment biologist with the Chippewa Ottawa Resource Authority, which regulates tribal fishing in the area.

They had some success but the whitefish population has dropped in recent years, making the Passover shortage worse, he said.
