Types of pest fish caught on the day
This invasive fish species goes back to the days of ancient Egypt. It was caught in Biblical times from the Sea of Galilee. Fisheries Queensland believe tilapia were first discovered in Townsville in 1978 and in 40 years have become known as the “cane toad of the waterways”. The 2011 floods in Ipswich and Brisbane helped tilapia disperse into many freshwater bodies throughout South East Queensland. They are a serious threat to native species in that they compete for food and space. Tilapia are built for survival and females can hatch 1000 eggs at a time. In Queensland, it is illegal to have tilapia in your possession (without approval of authorities) and if caught, must be humanely killed and disposed of away from the water body. There are substantial fines for keeping, feeding, giving away, selling or releasing tilapia into the environment.
BANDED OR BARRED GRUNTER:
Although native to northern Australia and the Lake Eyre Basin, the Bared Grunter has been introduced into South East Queensland waterways, outside their natural range. Populations are now well established in SEQ and northern NSW and, according to experts, may adversely affect the aquatic environment and other native fishes found in the area. They are often kept as aquarium fish but can be very aggressive to other species. Barred grunter can vary from 5-20cm and will eat almost anything. They are considered a pest fish in South East Queensland and should be destroyed if caught.
