Tight coupling to ecosystems and dependence on common-pool resources threaten fisheries aquaculture.
The failures of traditional target-species management have led many to propose an ecosystem approach fisheries promote sustainability. is necessary, especially account for fisheryecosystem interactions, but by itself not sufficient address two important factors contributing unsustainable fisheries: inappropriate incentives bearing on fishers and the ineffective governance that frequently exists in commercial, developed managed primarily total-harvest limits input controls. We contend much...
The precautionary approach and collaborative governance must balance deep-ocean use protection.
The British Columbia halibut fishery provides a natural experiment of the effects “privatizing commons.” Using firm‐level data from 2 years before private harvesting rights were introduced, year they implemented, and 3 afterward, stochastic frontier is estimated to test for changes in technical, allocative, economic efficiency. study indicates that (1) short‐run efficiency gains privatization may take several materialize can be compromised by restrictions on transferability, duration,...
Abstract Despite the extensive effort to research issues of allocative efficiency in fisheries, little empirical analysis technical (TE) fisheries exists. This study examines vessel using a stochastic production frontier based on sample sea scallop vessels operating Mid‐Atlantic between 1987 and 1990. Estimates TE are computed compared with input usage, resource conditions, economic performance, recently imposed regulations. The suggests that owners captains only partially compensate for...
The Fisheries and Marine Ecosystems Model Intercomparison Project (FishMIP) has dedicated a decade to unravelling the future impacts of climate change on marine animal biomass. FishMIP is now preparing new simulation protocol assess combined effects both socio-economic changes fisheries ecosystems. This will be based Ocean System Pathways (OSPs), set scenarios derived from Shared Socioeconomic (SSPs) widely used by Intergovernmental Panel Climate Change (IPCC). OSPs extend SSPs economic,...
This article considers the problem of managing multispecies fishing industries as one regulating production individual multiproduct firms. The New England otter trawl industry is examined within this framework. Empirical results derived from estimating a profitfunction indicate that management consistent with structures ofmultiproduct and costs would directly regulate inputs. Little support provided for applying traditional bioeconomic model to fishery studied.
Abstract Fisheries management faces a new era. Markets, in the form of individual transferable quotas (ITQs) and growing global integration fish markets, will increasingly provide organizing regulatory principle for many fisheries. Whether ITQs markets are panacea or Pandora's box managing fisheries is, as yet, unclear, requires additional experience to fully evaluate. This article reviews workings expected benefits ITQs, origin concept problems they were designed address, world‐wide...
Skipper skill or managerial ability plays a central role in the harvesting of fish and fishing power. Examining influences on catch rates, however, may be complicated, since is generally unobservable. Using panel data production activities Pacific Coast trawl fishery, we examine use fixed- random-effects models to depict by intervessel differences, representing differences technical efficiency. The model selected over fixed-effects model. We conclude that skipper more related finding fish,...
Abstract This paper addresses normative exploitation of common renewable resources with changes in technology and technical, allocative, scale efficiency that exacerbate the commons problem externality. Their impact depends on rate nature change, investment, state property rights. An augmented fundamental equation a modified marginal stock effect new account for disembodied embodied technical efficiency. Neglecting these generates misleading policy advice dynamic inefficiency...
Abstract Sharks and their cartilaginous relatives are one of the world's most threatened species groups. The primary cause is overfishing in targeted bycatch fisheries. Reductions fishing mortality needed to halt shark population declines. However, this requires complex fisheries management decisions, which often entail trade‐offs between conservation objectives objectives. We propose mitigation hierarchy (MH)—a step‐wise precautionary approach for minimizing impacts human activity on...
This article measures total factor productivity in industries that exploit resources held common. Particular attention is paid to the valuation and specification of situ commonproperty a neoclassical production technology, catchability resource, variations economic capacity utilization. An empirical analysis open-access Pacific coast trawl fishing industry demonstrates disentangling residual from changes resource abundance, its catchability, utilization hones finer precision, lowering mean...
