Harvesting regulation under quota management systems for ocean fisheries

摘要: Abstract Decisions about harvest levels are the most crucial responsibilities of fisheries managers, but outcomes always more or less uncertain. The risk depends largely on information available. Fisheries biologists, trained to assess probabilities from management decisions, too often also expected decide what risks should be taken. Emerging regimes based individual fishermen's quotas, best exem-plified by New Zealand's quota system, redirect incentives those with harvesting rights cooperate in improved management, including information-gathering. Under these regimes, decisions can made quota-holders themselves, although safeguards needed protect broader public interest resource management.
