Agriculture and Environment: Salmon

Introduction

Many involved in the salmon aquaculture industry believed that its growth would help take pressure off wild stocks of overharvested fish such as cod, which had once been an economic mainstay of the North Atlantic fishery where salmon aquaculture began.
While the industry clearly helps to provide consumers with fish while taking some pressure off of comparable wildstocks in the ocean, it has a number of other detrimental impacts that, on the whole, may actually endanger wild stocks.

These impacts occur at the level of individual salmon farms, but due to the open nature of oceans many can have much more far-reaching impacts as well.
