NOAA Fisheries is implementing a final rule (Amendment 20) to establish limits on how much quota share or annual cage tags an individual or business can hold or control over the course of a fishing year. Amendment 20 was formally approved on November 10, 2022, and this rule implements all measures in the amendment.

This action establishes:

  • Caps on quota share of 35 percent for surfclam and 40 percent for ocean quahog.
  • Caps on annual cage tags of 65 percent for surfclam and 70 percent for ocean quahog over the course of the fishing year.
  • These caps will be monitored based on the total amount of ‘potential control’ an individual or business has over the course of the fishing year. ‘Potential Control’ will represent any allocation held directly, or held by all owners (in the case of businesses) or all immediate family members (in the case of individuals).
  • The maximum duration of multi-year specifications actions to match the stock assessment schedule (four years for Atlantic surfclam and six years for ocean quahog).
