Dylan Burbank (right), and David Campbell, fish technicians for the non-profit Northern Southeast Regional Aquaculture Association, Inc. (NSRAA), measure and record the weight of eggs collected from chum salmon captured at the man-made spawning channels at Herman Creek, located near Haines, Alaska.
In 2014, 2.4 million eggs were seeded into these incubation boxes. The 2013 incubation box survival rate was 90%. Without the artificial spawning, natural survival is said to be only 10%.
Weighing the eggs is the way the technicians determine how many eggs are placed in the incubation boxes. After weighing, the roe will be fertilized with the milt and then placed in the incubation boxes. Over the winter the fertilized eggs will develop into fry. The incubation process is 100% natural. Fry are not fed. Once they are big enough, the fish leave the incubation boxes on their own.
Based in Sitka, Alaska, NSRAA conducts salmon enhancement projects in northern southeast Alaska. It is funded through a salmon enhancement tax (of three percent) and cost-recovery income. NSRAA also produces sockeye, chinook, and coho salmon.
Male chum salmon return to Herman Creek to spawn with female chum salmon during the fall chum salmon run. The chum salmon return to freshwater Herman Creek, tributary of the Klehini River after living three to five years in the saltwater ocean. Spawning only once, chum salmon die approximately two weeks after they spawn.
Chilkat River and Klehini River chum salmon are the primary food source for one of the largest gatherings of bald eagles in the world. Each fall, bald eagles congregate in the Alaska Chilkat Bald Eagle Preserve.
