Hawke’s Bay trawl fisherman Karl Warr “burned the candle at both ends, worked 90 hour weeks and lived meekly” until he could buy his own quota. That’s given him the freedom to innovate: he’s invented a cage that fits onto the end of a trawl net. He can modify the shape and size of the holes in the cage to allow juveniles and non-target fish to escape at depth (when fish with swim bladders are hauled to the surface they can get the bends, reducing survival rates). “I ultimately want a drafting gate connected to facial recognition software, so you could Bluetooth your shopping list,” says Warr. Not to mention harmlessly release bycatch. Already, his invention has reduced the mortality of undersized gurnard—one of his main target species—by 96 per cent. Now, Warr is working with NIWA to develop his invention further.
Shot on assignment for New Zealand Geographic Issue 160 November - December 2019.
