Fisheries in African reservoirs are typically multi -species and in most cases the fish resource is harvested with a number of gears. These characteristics complicate their management and the development of management procedures. Typically, long time series of data on catch and effort and length- or age-based catch are not available for these fisheries. This precludes the use of data intensive methods such as multi-species virtual population analysis. The principal aim of this thesis was to deve...

Sparked by anecdotal accounts of boat noise influencing the catch rates of commercial salmon trollers on the B.C. coast, acoustical studies of both boats and fish were undertaken. The study was in four parts: 1. Acoustical output of salmon trollers: Recordings were made of troll vessels and examined on a spectrum analyzer. Sonic output was predominantly of low frequency, under 300 Hz. Output levels at trolling speed (1-2 m/s) were about 20 dB re 1 μbar at 1 meter from the hull. Higher frequency ...

The thesis investigates the emergence of capitalist relations of production in the British Columbia salmon fishery, and compares this experience to those relations of production which developed in the British textile and United States steel industries. The development of the wage employee relations of production in the British textile industry, of the late 18th and early 19th centuries, was found to be a resolution to the problem capitalists' experienced in attempting to gain control of product...

Loose, Verne William

The purpose of this study is to investigate optimal exploitation of a Pacific salmon fishery under the assumption that exclusive property rights in a fishery have been vested in a single or sole owner. Based on a review of the existing fisheries economics literature which focuses largely (but not entirely) on long-term steady state analytics, it is argued that the associated modeling technique does not apply readily to Pacific salmon fisheries. This line of reasoning is supported by the develop...

Lake Liambezi in the Zambezi Region of Namibia, formerly known as the Caprivi Region, is shallow (<6m deep) and characterised by cyclic episodes of filling and drying. When full the lake supports a highly productive fishery and when dry the lake is completely dry and used for agriculture and grazing. In 2000 the lake filled, and between May 2011 and April 2012 was surveyed using beach seine, experimental gillnets and catch landing surveys to obtain information for conservation and management rec...

This dissertation investigates the implication of combining economic and ecological models in an effort to expand our knowledge of the complex problems associated with resource management. The motivation for this research arises from the perceived need to develop a better understanding of how the flow dynamics within a resource affect the efficient management of that resource. Following the introduction, the second chapter experimentally tests the theoretical models of agent behavior in patchy r...

The purpose of this research was to explore the impact of finfish bycatch on the ocean shrimp Pandalus jordani fishery using two methods. One method looked at the breakage of the shrimp by finfish bycatch in the nets. The other looked at the impact of bycatch on fishing decisions. At-sea research found that finfish bycatch contributes to the breakage of ocean shrimp. However, the impact is small relative to breakage caused by other handling procedures. Bycatch was measured from each net of a dou...

Finnell, Cory Scott

Very different economic implications come out of fishery models depending on whether fishermen are assumed homogeneous or heterogeneous in fishing skill. It is, however, common for economists to assume that fishermen are homogeneous in fishing skill. If fishermen are systematically different in fishing ability, any analyses of the political economy of private and public regulations that were based on an assumption of homogeneous fishermen, must be reconsidered. To test for systematic differences...

Pacific whiting (Merluccius productus) is commercially and ecologically one of the most important fishery resources in the Pacific coast of the United States. The fishery is currently going through a period of rapid and profound transformation that could cause a substantial redistribution of benefits among domestic users. Benefits from the Pacific whiting fishery consist of conflicting biological, social, economic and regional objectives. A major management issue is the problem of resource alloc...

Fishermen's and managers' perceptions of fishery issues are an important factor to consider when studying conflicts between the two groups. According to theories of conflict management, differences in perceptions may cause situations to be characterized by misunderstanding and mistrust, and may add to the difficulties in managing the conflict. A questionnaire was developed to determine whether there were differences in perceptions between fishermen and managers. Both groups responded to the same...

This thesis examines fishery-based conflicts (FBCs) and the oceanic sovereignty implications of FBCs in a world devoid of the East-West superpower rivalry. The argument herein is that in the absence of the Cold War rivalry, previously lower-priority economic and diplomatic issues rise to the forefront of international relations. The analysis suggests that political stability and naval enforcement capability play a significant role in whether a nation will commit its naval forces to defend its na...

The dynamics of an unfished population of the abalone Haliotis iris Martyn in Peraki Bay, Banks Peninsula, were studied from 1973 to 1976 and the population parameters interpreted with respect to exploitation of the species. As Haliotis iris cannot yet be aged, a size-class population model was developed along the lines of the Leslie (1945, 1948) matrix model. The population projection matrix incorporates mortality, recruitment and individual growth components, and operates on a population divi...

A model of a fishery with an uncertain fish stock is proposed to compare alternative management systems with individual transferable quotas (ITQs). Assumptions of the model include: (1) the fish stock fluctuates randomly year by year; (2) in-season stock depletion is small; (3) the total allowable catch (TAC) set by the quota authorities has a definite relation with the fish stock level; (4) the true value of the stock level is revealed only at the middle of each season, when the authorities rev...

Kinas, Paul G.

This work is about the use of Bayesian statistics in fishery stock assessment and management. Multidimensional posterior distributions replace classical parameter estimation in surplus-production and delay-difference models. The maximization of expected utilities replaces the estimation of optimal policies. Adaptive importance sampling is used to obtain approximations for posterior distributions. The importance function is given as a finite mixture of heavy-tailed Student distributions. The perf...

The Fishery Conservation and Management Act of 1976 took effect on March 1, 1977. By this Act the United States extended its management over fisheries to 200 nautical miles from shore. Extended fishery jurisdiction was expected to promote industry development and expand the contribution of the fishing industry to the economies of the coastal regions. Benefits to the Pacific Coast groundfish industry have, however, been less than were expected when the Act was passed. A spatial equilibrium model ...

Fisheries around the world are in collapse despite decades of research and attempts to manage them. While conventional bioeconomic models of fishery depletion are well-understood, reversing these trends has proven to be a stubborn problem, even in the presence of science-based management regimes. My dissertation uses empirical tools to uncover new insights into the biophysical dynamics that may be preventing stocks from rebounding. I focus on the effects of environmental variability, which preva...

The objective of this thesis is to study the optimal management of North Sea herring. The analysis is based on a dynamic bioeconomic model for a fish resource, consisting of a model of population dynamics and a net revenue function. The model of population dynamics is described by a delay-difference equation. The model distinguishes between natural growth and mortality in the existing stock as opposed to new recruitment to the stock, which takes place with a time lag. The model is estimated bas...

This thesis examines the Government of Newfoundland's decision to emphasize the inshore fishery at the expense of the offshore in the future development of the industry. The inshore fishery is labour-intensive and is composed of approximately 30,000 licensed fishermen who operate on a seasonal basis from Newfoundland's coastal communities. More than 10,000 privately-owned vessels - with maximum range of 50 miles - are deployed in this sector and account for 65% of total landed tonnage. These ves...

Catch, effort, fleet size and boat owner expenditure data were collected on Virginia's recreational marlin/tuna fishery for the 1983-1985 seasons. Logbooks, dockside interviews and a telephone survey were evaluated to determine which method was the most efficient and effective for collecting and estimating catch and effort for Virginia's pelagic recreational fishery. In 1984, logbooks were used to collect catch and effort data and fishing effort was estimated using Bochenek's method. Very few fi...

This study develops an improved method for understanding economic production relationships in small scale fisheries. This method postulates that gross revenue is a function of physical input quantities, and is based upon the transcendental logarithmic function to derive factor share equations for each of the five inputs in the model. The translog form was selected because of its flexibility, non-constant elasticity of substitution, and input interaction to give a more realistic representation of...

Throughout history, the effective management of common-property resources has continually eluded mankind. Typically, the problem of overutilization and overcapitalization of the world's fisheries has been approached from purely a biological standpoint. Little, if any, economic consideration has gone into the traditional modes of common recourse management. Consequently, existing programs have not been notably successful from both an economic or biological point of view. The purpose of this paper...
