We conducted similar bycatch avoidance programs in two New England fisheries: yellowtail flounder bycatch in the sea scallop closed area fisheries and river herring bycatch in the Atlantic herring and mackerel fishery. These species have different behavioral properties: sea scallops are sessile; yellowtail flounder are demersal with limited but unknown...
For decades, the management of the Dutch flatfish fishery has included a variety of measures including individual transferable quotas (ITQ) and the implementation of a co-management system without succeeding in recovering the fishery to sustainable levels partly because of the multispecies aspect of the fishery with the two main commercial...
Since 2006, French quotas are shared out into annual catch entitlements per producer organizations (PO) according a stable allocation key. On this basis, PO’s have imposed catch shares to their own members but allocation and management rules are heterogeneous between PO’s. The objective of the paper is i) to assess...
In multi-species fisheries managed under ITQs, the existence of joint production may lead to complex catch-quota balancing issues. Previous modelling and experimental research suggest that, in such fisheries, some fishers may benefit from the ability to trade packages of fishing quotas, rather than fulfill their quota needs by simultaneously bidding...
Individual fishing quota (IFQ) systems are typically expected to increase the profitability of a fishery and improve sustainability by ensuring catches remain within quotas. They can also have important distributional and ecological implications that result from shifts in catch and effort between different gears, regions, and habitats. In multispecies fisheries...
Individual transferable quotas (ITQs) have been used in several countries worldwide to regulate access to marine fisheries. While ITQs can improve the economic efficiency of fisheries, in practice their application rarely has the expected effects. In this study we compare the output predicted by an individual based model of quota...
The established of exclusive rights to fish is essential for tuna-Regional Fisheries Management Organizations to prevent overfishing, achieve sustainability, and to realize maximum economic benefits. Exclusive use or property rights may be based on catch, effort, or licenses, and similar systems can be used for bycatch. Unique issues arise compared...
Most fishermen are faced with several options in both long and short term planning of their activity. In this paper we study fishers short term decisions when different seasonal fishery options are available. This involves choices of spatial and temporal allocation of effort as well as use of varying fishing...
An economic survey of the commercial operators currently active in the Queensland Reef Line fishery has been carried out, as part of a research project aimed at evaluating options available to manage the fishery. We present the background analysis of the fishery used as a basis to develop the sampling...
