The commercial and sport fishery on the Great Lakes is collectively valued at more than $4 billion annually. The fishery consists of a blend of native and introduced species, some of which are regularly restocked. Common catches include lake trout, salmon, walleye and white fish. The greatest commercial fishing harvests were recorded in 1889 and 1899 at about 147 million pounds. Since then, the fishery has been threatened on three fronts: overfishing, pollution and nonindigenous invasive species. Recent years have seen a major resurgence as walleye fisheries recover in Lake Erie and new salmon fisheries develop in Lake Ontario. The region's inland waters offer many fishing opportunities as well. Blue-ribbon trout streams attract fly fishing enthusiasts and lakes offer a variety of fish, including crappie, bluegill, perch, pike and large- and small-mouth bass.
