The Barramundi (Lates calcarifer) can be found across tropical northern Australia and is the fish emblem of the Northern Territory. This large, carnivorous, silver fish can grow to more than a metre in length and more than 40 kilograms in weight. It has an average lifespan of around 20 years. An excellent eating fish, Barramundi are often fished for their economic, health and cultural importance. The lifecycle of the Barramundi takes place in both fresh and salt water. In wet season, eggs and larvae are washed from the ocean into wetland and mangrove habitats, where the young develop. After three to five years, the mature fish migrate from freshwater to estuaries and saltwater coastal shallows to spawn.
