Commercial Fishing in New Zealand

  • New Zealand’s commercial fishing sector has built over the last 30 years.
  • In the 1970s our fishing industry was largely an inshore affair.
  • Offshore waters, beyond our 12 nautical mile Territorial Sea, were fished by the Japanese, Taiwanese, Korean, and Soviet vessels.
  • With the introduction of the 200 nautical mile exclusive economic zone in 1977 and the introduction of the quota management system in 1986, many New Zealand companies went on to invest in fishing vessels to fish the available catch and onshore factories to process the catch.
  • The industry has also grown from being a predominantly domestic supplier to one of the nation’s leading export industries. In excess of 90 percent of all fish landed is exported.

Hunting The Hunters By Mary Sutherland

These facts is based on an article about Spiders.

  • Not all spiders catch their food in webs of silky silk.
  • Some hunt for their food, stalking and pouncing on their prey, in much the same way as a cat does.
  • Because many hunting spiders are night-shifting  workers, the best time to look them is after dark.
  • Six of the spider’s eight eyes work like mirrors.
  • They reflect back a little of any light that reaches them.
  • Light travels in straight lines, so if you hold you torch at eye level and shine it down into the eyes of a hunting spider.
  • If a spider is carrying an egg sac or even a piggy-backing it’s babies, you’ll know that it’s a female spider.
