On the Relationship Between Aquaculture and Reduction Fisheries
研究水产养殖增长是否威胁减量渔业的可持续性，分析不同管理机制下的风险，并探讨鱼粉市场结构（是否与豆粕等蛋白饲料竞争）对鱼价和捕捞压力的影响。
Recently, there has been a growing concern that increased aquaculture production poses an environmental threat to the species targeted in so‐called reduction fisheries, the main source for fishmeal. The argument is that increased aquaculture production leads to higher feed demand, and then presumably to higher fishing effort in these fisheries. In this paper we address whether aquaculture production threatens sustainability of such fisheries. First, we ask under which management regimes can increased demand pose a threat to the species in question? Second, we investigate what is the market for fishmeal; is fishmeal a unique product or is it part of the larger market for protein meals which includes Soyameal? This is an important issue since the market structure for fishmeal is a key factor in determining whether increased aquaculture production can affect fishmeal prices, and thereby increase fishing pressure in reduction fisheries.
