The Global Competition for Wild Fish Resources between Livestock and Aquaculture
研究发现鱼粉需求缺乏价格弹性，但技术进步正减少饲料中的鱼粉用量，表明对野生鱼类资源的强需求压力是暂时的。
Abstract Aquaculture satisfies a growing global demand for fish but also consumes an increasing share of the world’s wild fish resources. This has led to a concern that increased aquaculture production poses a threat to the sustainability of capture fisheries. We use a shrinkage estimator to estimate fishmeal demand from countries with different make‐up of meat and farmed salmon production. Although we are not able to identify structural differences between these sectors, the empirical results show that fishmeal demand is price inelastic. Technological change, however, is reducing fishmeal usage in feeds, suggesting that strong demand pressure on pelagic fish resources targeted for fishmeal is a temporary phenomenon.
