Monitoring at Goat Island Marine Reserve shows that numbers of crayfish and snapper are now lower than when the reserve was established in 1975.

Following the creation of the reserve, numbers of crayfish recovered quickly, increasing four-fold in number by the 1990s with snapper also becoming bigger and more common.

Leigh Marine Laboratory’s Dr Nick Shears attributed the decline to fishing on the reserve boundaries and the state of the wider fishery and said the pattern is similar at marine reserves at Tawharanui and Hahei.

He said that the reserve boundaries needed to be extended seaward to protect resident animals and to safeguard the scientific and recreational values of the marine reserves.
