By steering them into different parts of the net, the fish may encounter other measures like ‘square mesh panels’ or sorting grids which can help smaller fish or less desirable species to escape.

The Computer Vision System automatically identifying some whiting as they pass along a conveyor belt.
Dr Coby Needle, Chief Fisheries Advisor for Scotland said:
“Over the last ten years Marine Scotland has been a leader in the field of using machine learning to recognise, identify and count fish in video footage from cameras.
“Using computers to automate the process in this way is a great step forward as it is quite a time consuming task for staff to go through and review videos manually.
“By using cameras we have to send fewer staff to sea on fishing vessels, which saves money and exposes them to less risk.”
