The influence of biological characteristics on fisheries co-management : a game theory perspective

Creator:: Trisak, Jiraporn
Abstract:: Co-management is considered an alternative approach to fisheries management, however, not all co-managed fisheries have been successful. Most studies discussing the success and failure of co-management have emphasized economic and social attributes of success and failure, such as fishery rights and institutional arrangements. The effect on co-management of biological characteristics,...

Effects of sampling design, estimators, and variability on groundfish management in Oregon

Creator:: Crone, Paul R. Jr
Abstract:: Sampling error associated with estimates of species composition and age composition of commercial groundfish landings in Oregon from 1989 to 1991 is documented to evaluate the impact of variable landing data on fisheries management and monitoring programs. The statistical reliability and bias associated with two multistage sampling designs are investigated...

Statistical model selection criteria and their application to the Stock Synthesis assessment program

Creator:: Helu, Siosaia Langitoto
Abstract:: Statistical modeling has evolved around building increasingly more complex models, even though it is common knowledge among statisticians that an optimal model size usually exists for any given data set. Having overly complex models leads to imprecise parameter estimates and tends to increase the subjective role of the modeler, which...

Fishing location choices in Oregon trawl fisheries : are fishermen risk-averse or risk-prone?

Creator:: Trisak, Jiraporn
Abstract:: Despite the fact that fishing is an inherently uncertain business, risk has rarely been formally recognized in fisheries science or management. Few fishery management plans include any form of risk assessment and those that do focus on minimizing risk caused by uncertainty associated with markets and environmental conditions. Fishermen's attitudes...

The effects of harvesting Pacific hake (Merluccius productus) on the offshore community : the results of a multi-species model

Creator:: Gartz, Russell G.
Abstract:: The effects of harvesting Pacific hake (Merluccius productus) were examined with a multi-species numerical model composed of seven logistic growth equations coupled by a food web. The food web was composed of: California sea lions (Zalophus californianus), hake, sablefish (Anaplopoma fimbria), spiny dogfish (Squalus acanthias), a generic rockfish species (Sebastes...

Using Oregon trawl logbooks to study spatial and temporal characteristics of commercial groundfish species associations

Creator:: Lee, Yong Woo
Abstract:: Species associations of fifteen major commercial groundfish species in the northeastern Pacific ocean and their spatial and temporal characteristics were studied using Oregon bottom trawl logbook data, 1987 to 1993. Screening procedures were used to remove questionable data from the original logbook files, which resulted in the exclusion of information...

Distribution and assemblages of demersal fish in Oman

Creator:: Ambusaidi, Hilal Saud
Abstract:: The Sultanate of Oman has 1700 km of coastline extending from the Arabian Gulf south to the Arabian Sea. The demersal fish distributions and assemblages have not previously been well defined. In winter, variations in the oceanography of the area are minimal. In summer, however, the Arabian Sea is strongly...

Foraging strategies of Glaucous-winged Gulls : influences of sea otter predation

Creator:: Irons, David B
Abstract:: Diets and foraging strategies of Glaucous-winged Gulls were studied in areas with and without sea otters in the western Aleutian Islands, Alaska. Gulls foraged on invertebrates (e.g., sea urchins, limpets, chitons, mussels, and others) in the rocky intertidal community and on fish at sea; this study was conducted on gulls...
