Rock Lobster
ROCK LOBSTER

The commercial rock lobster fishery is New Zealand’s third biggest seafood export earner.

Rock lobster are caught commercially using baited pots. Once caught, most are held in temperature-controlled aquaria before being airfreighted “live” to export markets.

New Zealand's spiny rock lobster fishery is managed by strict quotas which allow only a set amount of spiny rock lobster to be taken commercially each year.

The fishery is also controlled by size restrictions: for a lobster to be of legal size, the width between the primary spines on the second segment of the tail must be greater than 54mm for a male lobster and 60mm for a female.

 

HISTORICAL OBSERVATIONS OF NEW ZEALAND'S QUOTA MANAGEMENT SYSTEM

I have had the privilege of studying the effects of New Zealand’s quota management systems (QMS) on participants since its 1986 implementation. I have done this on three sabbatical leaves (1986-7, 1995, 2005-6). Below I have outlined some key historical events and changes that have happened to New Zealand fisheries to give study tour participants a concise orientation.

Before October 1986 QMS implementation

During the 1970s New Zealand, like many nations, encouraged fishery development as 200-mile exclusive economic zones were established. By the early 1980s many people perceived problems of over-harvest and overcapitalization in NZ inshore fisheries. The government took the following steps:

By the mid-1980s, three events converged to form a “perfect storm” that led to the surprisingly rapid development and implementation of New Zealand’s individual transferable quota system. These included:

QMS Implemented in 1986

The initial quota management system (QMS) using individual transferable quotas (ITQs) implemented on October 1 for all major finfish fisheries was derived almost directly from a 1979 paper by Maloney and Pearse (Journal of Fisheries Research Board of Canada 36: 859-866). Key elements of the initial QMS design included:

Some of the early outcomes observed included:

Pre-1995 Changes

When I returned in 1995 to continue my study there had been significant changes to the QMS including:

Current Situation

Since my return in October 2005, I’ve observed the following changes over the past decade:
