Like agriculture, decisions regarding aquacultural production are complex. In addition to controlling harvest, feeding schedules, and culling rates, one must consider a number of practical considerations that may supersede other factors in economic importance. Among these pragmatic...

This paper examines the level and determinants of technical efficiency for a sample of domestic longline fishing vessels operating in Hawaii in 1993. The data on per-trip costs and revenues, fishing targets, vessel ownership, experience and education level of fishermen, vessel size, and vessel...

Norwegian spring-spawning herring (Clupea harengus) is the largest fish stock in the North Atlantic and is harvested by many nations. The introduction of new technology in the 1960s resulted in a substantial increase in the efficiency of the fishing fleet. As a consequence, the stock was fished...

Surplus production models have been used in fisheries analysis for over 40 years. The traditional surplus production model incorporates the assumption that catch per unit of effort is constant for a given stock size. As a result, effort can be indefinitely applied to the fishery in the short...

In this paper a bioeconomic simulation of the U.S. fisheries for silver hake, Merluccius bilinearis, is presented. The model design combines elements of age-structured population and harvest yield models with economics of the silver hake fishery. The analysis evaluates both biological and...

The effects of different harvesting strategies on the mean and variation in size of the fish stock and net revenues are investigated. The strategies analyzed are constant catch, constant effort, and constant escapement. A Gordon-Schaefer model affected by cyclical disturbances and stochastic...

This paper considers the prospects for cooperative multilateral management of the North Atlantic bluefin tuna fisheries in accordance with the United Nations (UN) Agreement on Straddling Fish Stocks and Highly Migratory Fish Stocks signed in December 1995. A three-players characteristic function...

Estimating a demand system under the assumption that preferences are homogeneous may lead to biased estimates of parameters for any specific individual and significantly different expected consumer surplus estimates. This paper investigates several different parametric methods to incorporate...

In the early 1990s, two major crises affected the French fish market. Low import prices were suspected to have affected import levels of fish. Therefore, this paper looks at the empirical economic factors of fish imports in France. Most economic papers related to this field use a demand function...

Heavy positively autocorrelated natural fluctuations in a fisheries stock level are problematic for fisheries management, and collapses in the stock dynamics are difficult to avoid. In this paper, we compare three different harvesting strategies (proportional harvesting, threshold harvesting,...
