Which National Standard sets the policy to prevent overfishing while achieving optimum yield?

• A. National Standard 2
• B. National Standard 1
• C. National Standard 5
• D. National Standard 8

Answer: (B)

This question tests a standard that requires preventing overfishing while achieving optimum yield. In fishery management, optimum yield means harvesting in a way that maximizes the benefits from the stock without driving it toward decline, so fishing pressure is kept at sustainable levels and the stock can replenish over time. The standard specifically ties conservation to harvest goals, guiding managers to set quotas or effort limits that prevent overfishing while still aiming for the best overall yield for the fishery and its communities.

That’s why the correct choice fits best: it embodies the policy to keep fishing mortality at a level that allows the stock to endure and provide long-term benefits, rather than pursuing maximum immediate catch. Other standards focus on different aspects—such as using the best scientific information to inform decisions, allocating fishing privileges, or considering ecosystem and social factors—but they don’t directly couple preventing overfishing with achieving optimum yield.
