The 90s, and potentially slightly earlier, saw the establishment of a commercial barramundi enterprise at Lake Argyle. This commercial venture included a number of ‘grow out cages’ on the lake. There were occasions when fish escaped from the cages due to net damage or harvest incidents. In the mid-90s professional fishermen catching silver cobbler on Lake Argyle started to find those barramundi escapees, catching them in their nets as the fish moved around the lake.
