Clearly, the aquaculture industry wants to avoid this scenario. Not only do escapes lead to large losses for the industry, but we also don’t want farm-raised salmon to mix and interbreed with wild populations.
Keeping an eye on what is going on inside the cages is critical for being able to respond and repair any damage promptly.
