Creator:: Weitzman, Martin L.
Abstract:: The paper analyzes the relative performance of two market-based fisheries management instruments in the presence of a stochastic stock-recruitment relation. Regulators are forced to choose either a fee per fish landed or a quota on the total fish harvest at a time when they are uncertain what will be...

Creator:: Costello, Christopher, Polasky, Steven, and Solow, Andrew
Abstract:: In this paper, we use a common renewable resource model with stochastic growth to obtain three main results. First, we demonstrate that predictions of poor future environmental conditions lead to lower desired escapement (i.e., low remaining resource stock in place after harvest) and higher current harvest. At first glance, it...

Creator:: Knowler, Duncan
Abstract:: Pollution of the marine areas that support much of the world's commercial fisheries is regarded as a pressing global environmental problem. One often-cited issue is nutrient enrichment, but this may be a mixed blessing: it contributes to primary productivity and increases the sustainable fish catch, while simultaneously causing occasional and...

Abstract:: This study was aimed at assessing how efficient the small - scale fishing units in Lagos State, Nigeria use the monetary inputs: costs of gear repairs, craft repairs, fuel, fishing losses, hired labor, and the residual costs of craft and gear. Between January and December, 113 mechanized and 43 non-mechanized...

Abstract:: Many records provide the bases for a clearer understanding of the roles of climate regime shifts and short-term perturbations in ecosystem dynamics, hence fisheries responses. Too few have taken the long view of the role of humans in this "Grand Fugue". As one of many predators, it is imperative that...

Abstract:: The aim of this paper is to specify the arising preferences within a theory of demand for seafood products through a socio-economic quantitative analysis. The relevance of standard economic variables is discussed by introducing additional socio-demographical variables in a multivariate statistical analysis. The position of seafood among other food products...

Creator:: Holland, Daniel S.
Abstract:: Although widely accepted, management systems that directly restrict catch or effort are neither efficient nor desirable for many fisheries, and have failed to conserve fishery stocks in many cases. Fisheries scientists have suggested that closing part of the fishery with marine reserves may sustain or increase harvest. These marine reserves...

Abstract:: Organizers convened an international workshop to address training necessary to produce effective managers for 21st century fisheries. The workshop involved government, industry, academic, and nongovernmental organization (NGO) leaders from Oceania, North America, and Europe. They addressed vision and management challenges of 21st century fisheries; requisite skills and knowledge; current training...

Abstract:: A discrete-time stochastic bioeconomic model is developed and used to analyse the North Sea herring fishery under alternative management regimes. The analysis focuses on how catches and harvesting policies change with the price of herring. Two production functions are used to explain the harvesting process. At small stock levels, the...

Creator:: Armstrong, Claire W., Armstrong, Richard J., and Reithe, Siv
Abstract:: A bioeconomic model allowing different degrees of harvesting closures for two sub-stocks consisting of mature and immature fish is presented. Hence the model opens for partial closures of fisheries on both sub-stocks. Migration between the two sub-stocks is defined as recruitment of the young to the mature sub-stock, and egg...
