Go out and catch a salmon this winter, take the fillets off and donate the rest to science.
The SA Government is encouraging recreational fishers to become citizen scientists and help protect the future of the state's iconic Australian salmon by donating filleted fish skeletons for research.
Participating tackle shops will have a donation form and are the drop off point for your frames. Anglers will also be running to win some great fishing prizes.
The skeletons or "frames" need to have head, gut and skeleton intact, so once the catch is filleted, the rest needs to be place them in a bag, along with a completed donation form.
The frames will end up in the labs of the South Australian Research and Development Institute, where they'll be studied to obtain information on size, age and reproductive status.
Minister for Primary Industries and Regional Development, Tim Whetstone encouraged anglers to participate.
"By donating Australian salmon frames, recreational fishers will help improve our biological knowledge of this species, which will inform how this important fishery is sustainably managed into the future," Mr Whetstone said.
"These school holidays, make the most of our pristine waters, get the kids out fishing and play your part in improving our scientific knowledge at the same time."
Minister's Recreational Fishing Advisory Council chairman Graham Keegan said the council was supportive of the research initiative, and encouraged all recreational fishers to make the most of fishing for Australian salmon during the colder months.
"Australian salmon are an iconic recreational species in South Australia. They are great fun to catch, especially on light fishing gear," Mr Keegan said.
"They're caught all year long in SA waters, especially along the mid coast, around the Fleurieu Peninsula and along the state's west coast in the cooler months.
"It's also a great target species for fishers of all ages and experience levels. Catch them and eat them fresh, as that's when they're at their best, then drop off the filleted frame at your local participating tackle shop."
You can drop off frames until September 30, 2020. The major funder of the research is the Fisheries Research and Development Corporation.
