New trawling technology was unveiled to New Zealands seafood industry. The system uses a large, flexible PVC tube
instead of a traditional mesh trawling net and could be put to use in New Zealand’s commercial snapper fishery within two years. The tube is towed behind a fishing vessel and contains small portals through which juvenile fish can escape. It is hauled on to a vessel full of water with the aim of keeping the fish inside alive. Once on deck, the water is released and the crew sort through the catch as it spills out. Any by-catch, such as sharks or stingrays – and juvenile fish that didn’t escape through the portals – can be released back into the ocean alive.
