Life Cycle of Australian Salmon

Studies have found out that generally the spawning season of Australian salmon begins in the month of March and lasts up to late April. Southern Western Australia is the sole spawning area for the salmon fishes and the whole of western species.

While they spawn in western Australian waters, the Leeuwin Current carries the juvenile salmons towards the eastern side. They reach the southern Australia nursery during the period of July to September.

Gulf central areas and the Coorong shelter payments provide them a shelter. After some years as the juveniles turn into adults, they migrate to the western Australian waters to contribute in the process of spawning. This is when the life cycle completes itself with the arrival of grown up salmons at the western coast. However some of the old fishes remain in the southern waters.

What is the Size of a salmon fish?

The Australian salmon fish’s maturity age falls in the life period of 3-6 years. They grow up to 70cm in length and can weigh up to 5 kilograms. During their life span of about 9 years they can grow up to 10.5 cm.

What do they eat?

Juveniles’ salmons live in the shallow waters of the nursery. Their diet is very simple and generally includes sea grass and small fishes. As they grow up, they move from the nursery areas to the more serious coast. Given their increased size due to age and the shift in the habitat, their eating habits also change. Now they eat more of herring-like fishes and pilchards.
