Waterfall in Chitina

"Here moosey, moosey . . ."

 

Low tide near the Hatchery

Literally dying to get upstream

Millions return

Males develop a humped back, hence nickname - humpies

Feasting


I forgot something! First up: while we were at Klutina, Ginger and Kathy spent some enjoyable time together in Chitina. They saw various critters, swans, moose, etc.

We visited the Soloman Gulch Fish Hatchery here in Valdez. They raise pink and silver salmon for the commercial and sport (respectively) fishery here in Valdez and the Prince William Sound. Pinks are a two year cycle fish, silvers are three year. We visited the area a few times in early morning and evening but to date have seen only one black bear and THOUSANDS of pink salmon. It was interesting to see just how determined these fish are to get upstream to spawn. They don’t know that their days are numbered. Here is the info from their web site: https://www.valdezfisheries.org/the-hatchery/

VFDA built the Solomon Gulch Hatchery (SGH) in 1981, and released its first pink salmon fry in 1982. It has operated consistently since then. The water for the hatchery is provided by the Solomon Gulch Hydroelectric Plant, owned by the Copper Valley Electric Association through a cooperative agreement.

VFDA employs a hatchery crew of twelve full and part-time employees, and is directed by Hatchery Manager Rob Unger. Other staff includes an assistant manager, fish culturists, maintenance support staff, and night watchmen. The hatchery staff lives in the Valdez community.

SGH has a permitted green egg capacity to incubate 270 million pink salmon and 2 million coho salmon each year. These egg capacities are strictly controlled by the State of Alaska. With this capacity, VFDA achieves annual releases of approximately 250 million pink salmon fry, and 1.8 million coho salmon smolt.

Egg take or spawning happens in late summer. Hatchery staff may spawn as many as 16,000 adult brood stock each day. These fish return to the hatchery spawning building by entering the facility using a fish ladder, which carry the fish from salt water to raceways on shore. Over the winter, the hatchery staff tends to the eggs as they hatch into alevin and settle into simulated gravel to subsist from their yolk sacs. In early spring, the fry emerge and are ready to go to sea. VFDA pumps the fry to net pens off shore where they are fed using commercial salmon feeds until they reach a target weight of at least 0.5 grams. From there, the smolts are released to complete their life cycle in the open sea. This process is known as ocean ranching. The adults, which average about 3.5 pounds each, return the following summer, and the process starts all over again.

Average adult returns to the hatchery are approximately 15.8 million adult pink, and 83,000 coho salmon. After harvesting a small percentage of the return for cost recovery and brood stock, the remainder is harvested primarily by the commercial purse seine fishermen.
