MAINE, USA — Maine's smelts, a small fish beloved by ice fishermen, appear to be continuing a rebound in population after years of decline.
Rainbow smelts come to shallow freshwater streams to spawn every spring, which make them a popular target of ice fishermen in the winter. Ice fishing shacks on frozen rivers are a common sight in some Maine towns, where fishermen sit for hours in the hopes of catching the fish.
But the health of the fish's population is in question, as the National Oceanic and Atmospheric Administration listed it as a federal “species of concern” in 2004. The Maine Department of Marine Resources has described the reasons for the decline as not well understood. Loss of habitat is one possibility.
Maine made it more difficult to fish for the smelts about five years ago with new restrictions, and recent years have shown positive signs. Reported catches of smelts from areas such as the Androscoggin and Damariscotta rivers have been above average, in terms of the size of the fish and the numbers caught per tide, said Michael Brown, a fisheries scientist with the state.
Maine’s marine resources department is conducting a new survey of smelt populations this year. The ability to perform the survey depends a lot on ice conditions, and on commercial operators being able to keep their fishing camps out on the ice, Brown said.
