Creator:: Idels, Lev V. and Ou, Beiyan
Abstract:: We study the combined effects of periodically varying carrying capacity and survival rates on the fish population in the ocean (sea). We introduce a new delay differential equation model with a control parameter which describes how fish are harvested. We consider a predation function as the function of the delayed...

Creator:: Weninger, Quinn, Perruso, Larry, and Bunzel, Helle
Abstract:: Data generating processes for trip-level commercial fishing data feature endogenous targeting of individual fish species and spatially, temporally varying stock conditions that are unobserved by the researcher but partially observed by fishermen. We present a model and identification strategy to address serious challenges that arise in this setting for obtaining...

Creator:: Quach, Thi Khanh Ngoc
Abstract:: Coral reef ecosystems provide many important services to society. Their importance is not only proved by their beauty but also because they provide food and livelihood for millions of people in communities around the world, especially in developing countries. This paper estimates the economic value of coral ecosystems and potential...

Creator:: Kaitala, Veijo and Hjermann, Dag
Abstract:: In the Barents Sea, recruitment of North-East Arctic cod is affected by sea temperature, being higher in warm years. Cod dynamics are furthermore influenced by time-lagged competition for capelin with herring, and the intensity of size-selected harvesting. The system is not stable in three ways: (1) the effect of temperature...

Creator:: Lorentzen, Torbjørn
Abstract:: Global warming is expected to affect the ecosystem in the Northeast Atlantic, and sufficient changes will also affect the aquaculture industry. Farming of salmon and trout is the biggest aquaculture industry in Norway. The export value was about 2 billion US dollars in 2005. The objective of the paper is...

Creator:: Nguyen, Minh Duc, Kinnucan, Henry, and Hite, Diane
Abstract:: The contribution of aquaculture development to the Vietnamese national economy and to farmers’ incomes has been documented in various government reports as well as working papers produced by development projects. However, the role of aquaculture in the life satisfaction of poor farmers has not been considered rigorously. In particular, it...

Creator:: Rossetto, Luca
Abstract:: Recently, Mediterranean lagoon environment, mainly in the North Adriatic area, has been threatened by the overexploitation of fishery. Fishing has been rapidly growing since clam (Tapes phippinarum) fishery has spread over several lagoons. Fishing growth has been accomplished by capital-intensive fishery equipments increasing harvesting beyond the sustainable biological growth. This...

Creator:: Tomberlin, David and Bosetti, Valentina
Abstract:: Real options models arguably provide a useful framework for understanding individual fishermen's investment decisions, which play an important role in fisheries management issues ranging from capacity reduction to stock assessment. While these models appear to predict actual behavior reasonably well, one important difficulty in applying them is that the salvage...

Creator:: Tveterås, Sigbjørn
Abstract:: The objective of this paper is to present a parsimonious forecasting model for the fishmeal price. The focus is on the soybean meal market’s impact on the fish meal price through the soybean meal futures price together with the stocks-to-use as an indicator of demand and supply conditions. A salient...

Abstract:: Vietnam is in the club of countries gifted with the long coastal line, and strong in marine features accordingly. Fishing operations are artisan characteristic and the management method is primarily open – access. Since the past few years, the yellow fin tuna long- lining fishery has become one sub-sector experiencing...
