Aquaculture: Not An Easy Answer To Overfishing

hat escaped, farmed salmon may lead to genetic degradation of wild salmon populations.

"Rapid growth in shrimp and salmon farming has clearly caused environmental degradation, while contributing little to world food security," the researchers said in the report. "These industries provide food mainly for industrialized countries, consume vast quantities of wild fish as feed, and generally do not generate long-term income growth in impoverished communities."

According to Lubchenco, salmon aquaculture in the Pacific Northwest faces similar issues.

"Now that some of these problems are being recognized, they can begin to be addressed," she said. "Incentives which reward good practices should be established, which could operate at local to international levels."

In the Science report, the researchers suggested that a good mechanism to improve production practices might be trade restrictions through the World Trade Organization that addressed the processes of production, not just quality of products.
