Peering through the smelt crystal ball

An old Wisconsin story tells of an impoverished family living near the mouth of the Peshtigo River and Lake Michigan in 1934. The two sons come back from chores with a laundry bucket full of unfamiliar silvery fish they found schooling in the river. The next day, the boys collected more fish, sold them at the market, and made money to pay off debt, buy food and clothes.

It was the Great Depression, and suddenly a new food fish was swimming the shores of the Great Lakes. It was the rainbow smelt, which is native to the Atlantic Ocean but escaped from a pond into the Great Lakes in the 1920s.

Lake Superior and Lake Michigan communities started what became known as “smelting.” On dark spring nights, people gather to net smelt as the fish spawn near shore. People like Carolyn Swartz, owner of the Angler’s All bait shop in Ashland, Wisconsin, have been smelting for decades. Sara Hudson, from Ashland Parks and Recreation, tells us about the smelting tourists that flood the city each spring.

Fish Biologist Jared Myers has done research on introduced smelt in Lake Superior. Jared is concerned about the negative impacts that smelt have on young native fish. How do smelt fit with the invasive and native species around them, and what happens when humans fall in love with a non-native species?
