THIS new video by Fisheries NSW shows underwater footage of a golden perch being released using a release weight.
The use of a lead release weight minimises the impacts of barotrauma on fish released after being caught from deep water, generally greater than 10m.
Note: the pole seen in the video clip would not normally be used; it was used in this case to hold the camera steady whilst capturing the footage of the fish being returned to depth.
The DIY release weight used in the video clip was about 150 grams in size.
