Climate change may cause significant changes in the distribution, abundance, and species mix of commercial fishery resources. In any given area stocks of some species may decline; stocks of other species may increase; and new species may appear in commercially significant volumes. However, it is difficult to predict what specific...
Fisheries exploited under open-access conditions create externalities, resulting in a range of problems associated with over-capitalisation and stock depletion. One answer to this is to shift the mode of production away from hunting and towards husbandry, an approach which becomes feasible where some control can be exercised over the resource...
Though long a standard technique in engineering and medical research, duration or survival analysis has
become common in economics only in recent decades, and in fisheries economics we are aware of only
one previous study. In this paper, we demonstrate the usefulness of duration analysis to understanding
fleet dynamics, specifically...
Spiny lobster (Panulirus argus) and related species represent one of the most important commercial fisheries targeted within the Gulf of Mexico and Caribbean regions. This important fishery extends from Florida (USA) to Brazil. The longlived, pelagic larval stage within the life cycle of spiny lobster reveal this species to be...
In the Philippines, the current licensing policy for commercial fishing does not significantly contribute to the general goals of fisheries management. It is a failure as a monitoring tool as evidenced by the absence of a comprehensive information system on fish catches, effort and area of operation. Fisheries licensing does...
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...
This study was commissioned by OWET to determine the possible economic benefits to Oregon and Oregon’s coastal communities from having a thriving wave energy industry. While wave energy industry growth will proceed along a continuous path, this study examines the economic impacts at three distinct stages: Research and Development Stage;...

A model for studying how destructive fishing practices may affect commercial fish stocks through their effect on habitat is presented. It may be used both for renewable habitat-types, like eelgrass (Zostra marina) or sponges, and also practically non-renewable habitats like corals. The model demonstrates the trade-offs between using destructive and...
This paper intends to ascertain whether the micro-commercial initiative of Marine and Coastal Management Department (M&CM) introduced in 2001 is contributing to the sustainable livelihoods of fishers in the community of Ocean View. Ocean View is located in the greater Cape Town metropole and was created by the Group Areas...
