In this episode, we learn about a tagging project which was set up to help protect the Dhufish which are unique to Western Australian waters. A prized sport fish, Dhufish have unfortunately been in decline for several years, so the more information the scientists can get about them the better. Simon joins up with local Two Rocks skipper, Paul Greenwood and his son, Jess who have been big supporters of the project and regularly catching and tagging Dhufish with over 300 to their boat. Having arrived at the first mark, the baits are dropped down and the rods are soon bent over. Several Dhufish are caught in quick succession with each then measured, recorded and tagged before release. Paul the skipper shows us how he uses a release weight, to safely release the fish back to the bottom attached to a barbless hook which is then teased out. We also learn how to prepare perfect squid baits for Dhufish fishing whilst Paul shows us the kind of bottom structure that Dhufish reside in. At the final mark, the gys find more Dhufish plus some Snapper and a surprise St George Whiting to round off the trip.
