13. The 2017 DIPAC Chinook forecast (adjusted for recent error) points to a marginal availability of females for broodstock at MSH. If the marine survival is even lower or the interception rate higher than anticipated, our green egg goal will not be attainable with returns to the MSH rack.

Returns to other hatcheries producing the Andrew Creek stock are experiencing the same decline in marine survival and may not be able to supplement MSH production in the near future.

New Fish Transport Permits (FTPs) has been approved that will allow DIPAC to collect brood and/or green eggs from returns to Fish Creek. Assistance in collecting eggs at this site has been pledged by the Territorial Sportsmen and ADF&G Sport Fish Division.

16. What is being done to improve DIPAC Chinook returns and better ensure broodstock in the future?
Completion of new rearing annex building in 2012 increased MSH capacity for kings (& cohos) by 40%. Additional production resulted in:
Creation of new rearing/release Lena Cove
Reinstitution of rearing/release of Thane saltwater site

On-going work with ADF&G Sport Fish Division:
Management of terminal area to protect broodstock in years of low abundance.
Temporarily increase MSH smolt release by reallocating a portion of Fish Creek production.
