Fleetwood and as transport became more efficient, more overnight visitors became day visitors. The Hillhouse plant was heavily cut back, and was finally closed in 1999. Most serious, however, was the collapse of the fishing industry, which was largely destroyed in the late 1960s and early 1970s by the Cod Wars, a dispute over fishing rights between Iceland and the UK. As Fleetwood's trawlers mainly fished the North Atlantic in search of cod, the loss of the fishing grounds hit the town hard.

Murray cod cod have also been known to eat ducks, cormorants, freshwater turtles, water dragons, snakes, mice, and frogs. The observations of the recreational fishermen fishing for Murray cod with surface lures at night reveal that the popular description of Murray cod as a demersal ambush predator is only partially correct. While this behaviour is typical during the day, at night, Murray cod are active pelagic predators, venturing into shallow waters and frequently taking prey from the surface. Murray cod reach sexual maturity between four and six years of age, generally five years. Sexual maturity in Murray cod is dependent on age.
