A Bioeconomic model of ocean acidification in the Baffin Bay/ Davis Strait Shrimp Fishery
We examine the case of the shrimp fishery in Baffin Bay/Davis Straight for potential effects of Ocean Acidification (OA), including: 1. the overall productivity of the shrimp fishery, 2. the spatial spread of the shrimp fishery, 3. the quality of the shrimp brought to market, and hence price and pro...
