Why aquaculture may not conserve wild fish.

We review literature on the displacement paradox and the Jevons paradox, with consideration of their implications for the potential effects of aquaculture on wild fisheries. The Jevons paradox refers to circumstances where improvements in the efficiency of resource use lead to growth in consumption and therefore undermine conservation. The displacement paradox refers to circumstances where increasing use of a potential substitute for a resource (e.

Aquaculture and the displacement of fisheries captures.

In modern aquaculture, animal-production technology is used to increase aquatic food sources. Such controlled rearing of seafood can, in principle, shift the pressure off wild stocks and aquatic ecosystems by reducing fishing activities, which may advance marine conservation goals. We examined resource displacement-the reduced consumption of a resource due to its replacement with a more environmentally benign substitute-in fisheries.

The tragedy of the commodity and the farce of AquAdvantage Salmon.

The US Food and Drug Administration is expected to approve AquAdvantage Salmon as the first genetically modified animal for human consumption. The genetic modifications allow the proprietary fish to grow at a rate twice as fast as a wild salmon, leading to greater ‘efficiency’ in terms of reduced costs and reduced time to market. This article provides an analysis of the ways in which AquAdvantage Salmon exemplifies capitalist market forces controlling and guiding the terms of salmon recovery and conservation.
