            Scientists in Seward working on techniques for hatchery rearing king crab have developed a method to boost survival rates among blue kings. Ben Daly, an Alaska Sea Grant research biologist, says he wasn't entirely surprised that micro algae worked so well.

 

 

-- (Crab 1                    38 sec              "There's been some culture ... flushed out of the tank.")

 

            What they did was to flush the water from the tanks less often:

 

-- (Crab 2                    22 sec              "We sort of used this semi ... really high survival.")

 

            Daly said they were able to successfully rear red king crab without using micro alga:

 

-- (Crab 3                    22 sec              "And this is beneficial in ... hatchery logistical standpoint.")

 

            Once the crab are out of the larval stage, Daly told KMXT they are much easier to rear in the hatchery:

 

-- (Crab 4                    35 sec              "They tend to be more hardy ... not quite as aggressive.")

 

            The Alaska King Crab Research, Rehabilitation and Biology program is a joint effort by several agencies and organizations seeking to someday restock depleted Kodiak Red King and Pribilof Blue King crab stocks.
