Reference Point

Reference points are quantitative (numerical) values that inform managers about the current status of a stock. Two important types must be considered, target and threshold (or limit) reference points. Target reference point is a numerical value that indicates that the status of a stock is at a desirable level; often management is geared towards achieving or maintaining this target. Threshold (limit) reference point is a numerical value that indicates that the status of a stock is unacceptable (e.g., overfished or too small) and management action should be taken to improve stock status.
