What is an Overfishing Limit (OFL)?

• A. The maximum harvest level allowed by law.
• B. The annual catch limit after precautionary buffers.
• C. The sustainable yield threshold that triggers reporting.
• D. The maximum harvest level that will not result in overfishing for the stock in a given year.

Answer: (D)

The main idea here is understanding what an Overfishing Limit represents in fisheries management. The Overfishing Limit is the maximum amount of catch in a given year that is allowed without risking overfishing of the stock. It acts as a scientific upper bound used to guide how much can be caught, and it’s typically used as the starting point for setting the annual catch limit (ACL) with precautionary buffers to account for uncertainty. That’s why the statement describing it as the maximum harvest level that will not result in overfishing for the stock in that year is the best fit.

The other descriptions mix in legal caps or the actual enforceable limit after buffers (ACL), or refer to thresholds for reporting rather than the scientific cap that protects against overfishing.
