Economists have long promoted fishery rationalization programs, but ITQs may fail to address the
ecological consequences of fishing. Of particular concern is that economic incentives to harvest larger
fish (due to size-dependent pricing or quota-induced discarding) can destabilize fish populations or lead to
evolutionary changes. A substantial theoretical literature in...
The credit crunch has had a dramatic effect within the seafood industry. Recent years saw a buoyant UK economy with increasing sales of chilled seafood material and a growing interest in sustainability. Credit tightening and declining consumer confidence has placed pressures on these trends. This is unlikely to be reversed...
This study estimates the demand for saltwater recreational angling trips
within the Southern California Commercial Passenger Fishing Vessel
(CPFV) fishery. The CPFV fishery provides a variety of trip types to
support recreational anglers targeting several species including, tuna,
rockfish, yellowtail, and shark. Trips vary by fishing location, by length of...
Many of the coastal counties in Florida have active artificial reef
deployment and monitoring programs. These reef systems have been
shown to be an important destination for the marine recreational boating
industry, as well as for the for-hire commercial sector (i.e., six-pack charter
vessels, guide boats, party/head boats, and dive...
The motivation of this paper is to detail the application of Markov chains in
simulating fleet dynamics in Australia's Northern Prawn Fishery (NPF).
The Markov chains are enhanced through the use of the multinomial logit
(MNL) and Seemingly Unrelated Regressions (SUR) models to explain
transition probabilities. The terms MNL Markov...
The past twenty years has seen the offshore outsourcing of post-harvest
fish processing gain unprecedented momentum. The growth in offshore
processing is a further stage in an increasingly globalised fisheries value
chain. Raw material is head and gutted, then frozen, and transported to
processing sites in Asia (especially China). The...
The spatial, multi-species nature of coral reef fisheries makes them notoriously difficult to manage. We
have developed a simulation modeling approach to examine the effect of management options on the
recreationally important tourist destination of Ningaloo Reef in Western Australia where a recreational
fishery targets Spangled Emperor (Lethrinus nebulosus). The...
This paper is based on a review and assessment of lessons from three
projects on fisheries co-management in Bangladesh: i) Community-based
fisheries management (CBFM), ii) Management of aquatic ecosystems
through community husbandry (MACH), and iii) Fourth Fisheries Project
(FFP). These co-management initiatives established 191 Community Based
Organizations (CBOs) in 179...
Due in part to limitations in data and models, fishery managers have been
hindered in their efforts to simultaneously address economic and ecological
effects of management measures. In the US, this promotes violation of
National Standard 8 of the Magnuson Stevens Fishery Conservation and
Management Act, which mandates that conservation...
The paper develops a model of recreational fisher behaviour in which
fishers maximize their individual utility by adjusting fishing time, trips,
catch and size of fish caught. It investigates the optimal behaviour or an
individual fisher with and without constraints such as bag limits. The
model is used to assess...
