Which statement about OFL is true?

• A. OFL is a guaranteed catch level for the next year
• B. OFL is an estimate of harvest that will ensure profit
• C. OFL is the minimum catch necessary to support fishing activity
• D. OFL is the maximum harvest level that will not result in overfishing for the stock in a given year

Answer: (D)

The main idea here is that an Overfishing Limit (OFL) sets the upper bound on what can be harvested in a year without risking overfishing. It’s a scientific ceiling used to guide annual catch decisions, and in practice, regulators typically set the actual catch limit (with additional safety buffers) below this level to account for uncertainty.

That’s why the statement describing OFL as the maximum harvest level that will not result in overfishing for the stock in a given year is the best fit. It captures OFL as the threshold beyond which overfishing could occur, and it explains why managers use OFL to inform lower limits like ABC or ACL. The other options don’t align with how OFL is defined: it isn’t a guaranteed catch for the next year, it isn’t an estimate aimed at ensuring profit, and it isn’t the minimum catch necessary to support fishing activity.
