Catch methods

Twenty-five years ago two-thirds of New Zealand’s mid and deepwater fisheries lay largely undeveloped, while aquaculture was a far off dream of marine farm pioneers. It’s a very different picture today.

Around 650,000 tonnes of seafood are harvested from New Zealand’s coastal waters and Exclusive Economic Zone each year. Almost 63 percent of this harvest is mid and deep-water fish, 12 percent is pelagics, 10 percent is inshore species and 15 percent is from aquaculture.

Following are the definitions of the different New Zealand fisheries and the types of fish found within them. The catching methods on the left give you more detail about how the species in each of the fisheries are caught.

“Aquaculture” – the inshore farming of certain species – is also described here but for more detail see Aquaculture ยป
