Hatchery Certification requirements for shellfish:

  • Separate broodstocks are from the same sources and locations from year to year. Broodstock and seedstock must be physically or geographically isolated from non-certified stocks through all stages of culture.
  • No detection of disease or pathogens in any of the shellfish stocks present at the facility.
  • Live samples for histological examination submitted to the ADF&G*, or other approved, pathology laboratories 60 days prior to transport requests. Samples required are:
    • 60 live adult animals from the parent broodstock,
    • 60 live spat from the cohort of animals proposed for transport,
    • 1,000 larvae (if applicable)
  • Disease history information.
  • An operating plan and schematic layout for the facility.

The department provides a written disease report to a shellfish hatchery or nursery regarding submitted samples within 120 days after receipt of the seedstock.

The annual certification typically runs for a twelve-month period beginning March 1st and ending February 28th of the following year, but may vary depending on the date of receipt of an approved disease history report.

Renewal of the certification requires:

  • histological examination of 60 live spat from the year class to be transported
  • an updated broodstock disease history
  • a statement of the hatchery performance reviewing success, problems, and mortality during the previous growing season.

Seed Distribution Facility Certification requirements for shellfish:

  • Separate seedstock from the same sources and locations from year to year. Seedstock must be physically or geographically isolated from non-certified stocks through all stages of culture.
  • No detection of disease or pathogens in any of the shellfish stocks present at the facility.
  • Live samples for histological examination submitted to the ADF&G* 60 days prior to transport requests.
    Samples required are:
    • 30 live spat from the cohort of animals proposed for transport,
    • 1,000 larvae (if applicable)
  • Disease history information.

The department provides a written disease report to a shellfish hatchery or nursery regarding submitted samples within 120 days after receipt of the seedstock.

The certification typically runs for a twelve-month period beginning March 1st and ending February 28th of the following year, but may vary depending on the date of receipt of an approved disease history report. Certification can extended longer if there is a favorable disease history report over many years.

Renewal of the certification requires:

  • histological examination of 30 live spat from the year class to be transported
  • updated seed stock disease history
  • a statement of the seed distribution performance reviewing success, problems, and mortality during the previous growing season.
