Book excerpt: In the formulation of fisheries management plans required under the Fisheries Conservation and Management Act of 1976 specific attention is paid to the "capacity" of domestic fishing vessels to harvest the predetermined optimum yield on an annual basis. Capacity is interpreted in this thesis as the technical harvesting potential of the fishing fleet over a specific period of time. In this context capacity reflects the size and composition of the fishing fleet of interest. The primary emphasis of this thesis was to identify economic, factors which affect harvesting capacity in the fishery. In this regard the long-run decision-making behavior of individual fishermen was of interest since the size and composition of the fleet, and hence harvesting capacity, is affected by specific choices made at the individual level. A theoretical analysis of the long-run decision making of individual fishermen was developed and was followed by an empirical application to a sample of fishermen who were active in the Oregon trawl fisheries during one or more of the years 1970-1975. The theoretical discussion initially centers upon those aspects of the fisherman's choices which detract from the application of a contemporary flexible accelerator type model to the analysis of fisherman decision behavior. Instead the logit approach was chosen to analyze discrete choice decisions that occur at the individual level in the Oregon trawl fisheries. Logit analysis is specifically designed to handle qualitative dependent variables and theoretically allows for the differences in decision rules among members of the decision-making population. In addition, the results of the logit analysis at the individual level can be extended to the population level to examine aggregate behavior of interest to fishery policy makers. The logit approach was applied to a number of individual decisions that affect technical capacity and the distribution of technical capacity in the Oregon trawl fisheries. The first logit model analyzed the decision of whether to leave or continue trawling. The next logit specification described the fisherman's choice of trawl fishery where the set of fishery alternatives in the Oregon case is comprised of the shrimp, groundfish and combination (groundfish and shrimp) fisheries. The last decision concerned the fisherman's choice of fishing vessel where vessels were classified according to gross tonnage and age. In general the analytical results reflect the simplicity of the initial specifications. Nonetheless, the potential of the logit approach for analyzing fisherman decision-making behavior was reasonably well demonstrated. Finally, several modifications and extensions of the preliminary work were discussed which, in the light of more specific data, would lead to a more complete, predictive and policy-oriented analysis of harvesting capacity in the fishery.

Available in PDF, EPUB and Kindle. Book excerpt: Growing demand for limited quantities of fish has led to systematic planning for the conservation and management of U.S. fishery resources. There is a need for better understanding of the complex biological and social environment on which regulation for conservation, social, and economic purposes is imposed. The behavior of commercial fishermen, who in many instances use multi-purpose vessels to exploit multi-species fisheries, is difficult to assess and predict. The purpose of this thesis is to describe and analyze selected aspects of Oregon commercial fishing fleets. The focus of this study is on the short-run decision-making behavior of Oregon trawl fishermen for the period 1974-1979. A general review of the activities of Oregon's multi-purpose fishing fleets is followed by an attempt to measure the responses of trawl vessel operators to varying economic and biological conditions. Several models of the short-run allocation of fishing time by a multi-purpose vessel operator are developed. The limited amount of economic literature on multi-purpose fleet behavior is briefly reviewed. An important feature not explicitly recognized in the theoretical models is that fishermen operate in an uncertain environment. Fishermen are hypothesized to react to expectations about economic returns in the fisheries which they can exploit. Simple Nerlovian agricultural supply response models were adapted for statistical analysis of the allocation of fishing time. Fishermen's short-run behavior was hypothesized to depend on expectations of current rather than normal returns to fishing time. Four versions of models which explain allocation of fishing time for a stable subfleet of trawl vessels were estimated using ordinary least squares regression. Monthly days of fishing by fishery were significantly explained by variables representing expected gross revenues per unit of effort, weather conditions and seasonal regulations. The analysis also indicates that fishermen are able to respond rapidly to perceived variations in gross returns. In the shrimp and crab fisheries, elasticities of days fished with respect to expected gross returns were estimated to be in the range of 0.45 to 0.40. Regulatory implications are that: (1) fisheries managers need to monitor the effects of regulation with little delay and (2) the use of taxes and subsidies to shift significant amounts of effort among fisheries is not likely to be successful. Additional research effort could profitably be spent to refine measurement of the explanatory variables, or to measure the response of individual fishermen to suitable explanatory variables.

Available in PDF, EPUB and Kindle. Book excerpt: Excessive fishing capacity is largely responsible for the degradation of marine fisheries resources, for the dissipation of food production potential and for significant economic waste, especially manifest in the form of redundant fishing inputs. The globalization of this phenomenon and the impact of excessive fishing capacity on the biological and economic condition of many fisheries throughout the world have been a matter of increasing concern in recent years. This led FAO to organize a Technical Working Group on the Management of Fishing Capacity in La Jolla, USA, from 15 to 18 April 1998. Selected papers prepared as reference material for this meeting are presented in this FAO Fisheries Technical Paper. Chapter 1 reviews underlying economics and methods of control. Specific aspects of high seas fisheries are addressed in Chapter 2. Chapter 3 explores extensively the many issues raised in measuring fishing capacity and capacity utilization. Chapter 4 briefly discusses the difficulties associated with the assessment of fishing capacity at global level.
