What does ABC stand for and how is it used in setting the ACL?

• A. Adaptive Biological Catch; used to adjust ACL in response to new data
• B. Acceptable Biological Catch; used to set the ACL after precautionary buffers
• C. Annual Bycatch Conservation; used to cap harvest
• D. Active Biological Constraint; used to determine OFL

Answer: (B)

ABC stands for Acceptable Biological Catch. It represents the portion of the stock’s scientific catch limit that has been adjusted to account for uncertainty and to apply precaution. The ACL is then set at or below that ABC, turning the scientific guidance into a binding annual harvest limit. In other words, ABC is the reference point used to determine the ACL after applying precautionary buffers to the stock assessment. The other options refer to terms that aren’t standard or describe different uses that don’t align with how the ACL is established.
