Unless appropriate substitutes are found, the growth of the aquaculture sector is likely to push prices of fishmeal and fish oil production higher.

These higher prices can create incentive for overfishing in poorly regulated fisheries. It also encourages industrial fisheries not to limit their quantities of by-catch (the other species caught in their nets), which impacts marine ecosystems. Between mid-2005 and mid-2008, the prices of fishmeal and fish oil rose by 50% and 130%, respectively. | ||
