New research shows there are about seven times more crayfish and 40 times more blue cod of legal catch size within a Tasman Bay marine reserve than in nearby coastal areas.

Conservation Minister Nick Smith has released the research carried out for the Department of Conservation at the Tonga Island marine reserve on the coastline of Abel Tasman National Park and at the Horoirangi marine reserve north of Nelson.

Shallow lobsters are eight times more abundant and deep lobsters 6.8 times more abundant in the reserve than in the control sites.
