Cod Wars Third Cod War (November 1975 – June 1976) began after Iceland again extended its fishing limits, now to from its coast. The British government did not recognise the large increase to the exclusion zone and so an issue occurred with British fishermen and their activity in the disputed zone. The conflict, which was the most hard-fought of the Cod Wars, saw British fishing trawlers have their nets cut by the Icelandic Coast Guard, and there were several incidents of ramming by Icelandic ships and British trawlers, frigates and tugboats. One of the most serious incidents occurred on 11 December 1975.
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.
