Citizen scientists in Australia can help the Western Australia Department of Fisheries by donating fish skeletons to help long-term monitoring program of fish stocks. Also known as 'frames', filleted skeletons, with the heads and guts intact, are essential for researchers to be able to assess the status of local fish resources. By analyzing data from the frames researchers can make science-based decisions to sustainably manage fisheries. Further information can be found here and here.
