Aquaculture and Capture Fisheries: a Conceptual Approach toward an Integrated Economic-ecological Analysis
نویسنده
چکیده
& This study presents a framework for analyzing the interactions between aquaculture and capture fisheries in the context of ecosystem-based management. We extends a model of the economic and ecological systems in coastal New England by incorporating an aquaculture sector in a computable general equilibrium (CGE) model and by examining the forage fish and aquaculture link in a marine food web. We show that aquaculture and commercial fisheries interact in a complex way throughout the economic and ecological systems.

Prediction of global sea cucumber capture production based on the exponential smoothing and ARIMA models
Sea cucumber catch has followed “boom-and-bust” patterns over the period of 60 years from 1950-2010, and sea cucumber fisheries have had important ecological, economic and societal roles. However, sea cucumber fisheries have not been explored systematically, especially in terms of catch change trends. Sea cucumbers are relatively sedentary species. An attempt was made to explore whether the tim...

متن کاملThe ecological basis for economic value of seafood production supported by mangrove ecosystems
The undervaluation of natural products and ecological services generated by mangrove ecosystems is a major driving force behind the conversion of this system into alternative uses. This trend of undervaluation is partly due to the difficulty involved in placing a monetary value on all relevant factors, but lack of ecological knowledge and a holistic approach among those performing the evaluatio...
متن کاملSustainable Ecological Aquaculture Systems: The Need for a New Social Contract for Aquaculture Development
l Ecohistories of aquaculture suggest that aquaculture is a natural part of human development throughout history and that modern, industrial aquaculture could strengthen its social and ecological roots by articulating its evolution along a sustainability trajectory and by adopting fully the Food and Agriculture Organization (FAO) ecosystems approach to aquaculture (EAA; Soto et al., 2008). The ...
متن کاملFish as food: aquaculture's contribution. Ecological and economic impacts and contributions of fish farming and capture fisheries.
Historically, the oceans were considered limitless and thought to harbour enough fish to feed an ever-increasing human population. However, the demands of a growing population, particularly in poorer countries, now far outstrip the sustainable yield of the seas. At the same time as fishing has become more industrialised, and wild fish stocks increasingly depleted, aquaculture production—fish an...
