Why track fish?
Determining where, when and why fish move is critical in understanding the distribution and availability of fish for fishing, and forms a basis for the sustainable management of fisheries. Fish move for a variety of reasons, including spawning, feeding and to avoid unfavourable environmental conditions. Tracking the movements of fish enables scientists to identify valuable fish habitat and important spawning grounds, and also determine how fish are likely to respond to changes in the environment.
|What to do if you catch a tagged fish?|
All fish implanted with an acoustic transmitter have also been tagged with an external tag. These external tags are yellow in colour and inserted beside the dorsal fin. Printed on each yellow external tag is a unique code that identifies the fish, as well as a phone number (1800 652 598) to report the catch.
If a tagged fish is caught, we recommend that the fish be handled gently and released. If possible, fishers are encouraged to record the tag number, weight and length of the fish, as well as the time, date and place of capture – but only if this does not cause the fish too much stress.
If fishers are not able to release the fish alive, they are encouraged to store the frame (the fish carcass minus the fillets) by freezing and contact Dr Jeremy Hindell to arrange for the collection of fish for aging and chemical analysis.
Fishers who report a catch will receive a certificate which identifies the fish they have caught, and provides a summary of where and when the fish has moved.
