NOAA’s National Marine Fisheries Service (NMFS) recently completed two reports on excess harvesting capacity, National Assessment of Excess Harvesting Capacity in Federally Managed Commercial Fisheries and Excess Harvesting Capacity in U.S. Fisheries: A Report to Congress. This paper presents the definitions of harvesting capacity, excess capacity, and overcapacity used in...
In many fisheries, the harvesting pattern shows considerable intra-year variation. These fluctuations give
challenges for downstream firms in value chains where predictability and continuity in the flow of production are important. Seasonal harvesting may well be rational from an economic perspective, as migration patterns can give huge variations in catch...
Under the reauthorized Magnuson-Stevens Act (MSRA), US fisheries management councils must specify an annual catch limit (ACL) for each managed species and institute accountability measures (AMs) to ensure that actual harvest will not cause the stock to be overfished. While the details of implementation are still being developed, a set...
In 2001, New Zealand modified its quota management system (QMS) to function as a hybrid ITQ/tax system. Catches in excess of annual catch entitlements (ACE) incur payments, called “deemed values”. The deemed value
system was part of the reforms that separated ACE from quota, which reduced transactions costs for both...
A key issue in fisheries restoration is the speed at which recovery can occur, while still meeting the
economic and social constraints which managers must deal with. This paper uses the viable control approach to examine fisheries restoration and study the tradeoffs involved with the selection of recovery strategies. We...
Conflict between the recreational and commercial sectors in New Zealand is largely limited to the fishery within the Territorial Sea. Although most of New Zealand’s fisheries’ value comes from mid to deep water stocks outside the Territorial Sea, there are a number of commercially valuable inshore fisheries.
Traditionally, conflict between...
This paper will address the effectiveness of fisheries co-management between the Ministry of Fisheries and Te Arawa a central north island indigenous tribe of Aotearoa/New Zealand. The Ministry of Fisheries, as the manager of fisheries resources, must provide a balance between the interests of all New Zealanders and the rights...
In many situation, fishing activity adversely impacts the state of the marine ecosystem, impacts which feed back to affect fish stocks. Some ecosystems appear to have multiple equilibria and exhibit hysteresis, whereby they can become stuck in low productivity states. We show how adding ecosystem dynamics to a classic fisheries...
This paper briefly describes the past development of the Bali Strait small pelagic fishery, and presents the impact of increasing fishing pressure and climatic variable on the quantity of catch. This paper then presents an estimate of its rent potential and the impact of increasing fishing pressure on rent at...
