Stock assessment of the return of early-run chinook salmon to the Kenai River, 1993
by Alaska Dept. of Fish and Game, Division of Sport Fish in Anchorage
Written in English
The total inriver return of early-run chinook salmon Oncorhynchus tshawytscha as estimated through hydroacoustic techniques was 19,921. The estimated angler effort and harvest as measured from a creel survey during the early (May and June) chinook salmon run were 153,899 angler-hours and 7,727 chinook salmon, respectively, approximately 25% greater than the 1974-1992 mean. Release mortality was estimated at 219 fish. Spawning escapement, which was estimated by subtracting total fishing mortality from total inriver return, was 11,975. This escapement was 2,975 (33%) greater than stipulated by the Kenai River Early King Salmon Management Plan. The predominant age class of both the inriver return and the recreational harvest of early-run chinook salmon was 1.4 fish. Migratory timing models were used to project spawning escapement during the 1993 fishery. No restrictions of the recreational fishery were required to achieve the escapement. A model based on sibling ratios was used to forecast the 1994 return at 20,089 (SE = 7,149) fish.

The Chinook Salmon Stock Assessment and Research Plan recommended an annual project to estimate juvenile abundance in the Kenai River by run (early and late) but this work was considered a low priority by staff and resources were concentrated on adult sampling projects.
Marine Sampling Adult Harvest, Genetics, and Coded Wire Tags. The Copper River Chinook salmon stock is composed of six major spawning stocks. Upriver stocks, like the Gulkana and Chistochina, are genetically distinct and exhibit early run-timing patterns; these stocks are targeted by fishers because of their early entry in to the river and importance to commercial, subsistence, personal-use, and sport fisheries.
If you are looking for Chinook salmon to fish, you need to know where they will be at any given time of the year.
Salmon spend the majority of their lives deep in the sea. They only come into. Stephen Hammarstrom has written: 'Stock assessment of the return of early-run chinook salmon to the Kenai River, ' -- subject(s): Statistics, Fish populations, Chinook salmon, Fishery. The Kenai River has two stocks of chinook salmon: (1) an early run which enters the river from mid-May through June, and (2) a late run which enters the river from late.
The State of Alaska’s 5 AAC Kenai River and Kasilof River Early-run King Salmon Management Plan identifies an optimal escapement goal of 3, to 6, Chinook Salmon 75 cm mid eye to tail fork length and Alaska Department of Fish and Game (Department) estimated only 2, large Chinook Salmon had passed their sonar site through June 16 and is projecting an inriver.
ADF&G just issued a news release saying that the early run Kenai River chinook is closed for the season. EXPLANATION: This emergency order closes the Kenai River to sport fishing for early-run king salmon.
The Kenai River will be closed to sport fishing for king salmon from the mouth upstream to the outlet of Skilak Lake and in the Moose River from its confluence with the Kenai River.

Kenai River King Salmon Run: Two runs of King Salmon are expected with the Early Run from mid-May to July and the late run is from early July to season closure in late July or early August.
Kasilof River King Salmon Run: King Salmon arrive in Late May until the end of the season typically in late July. The Kenai River receives two separate runs of Sockeyes, the first beginning in mid-June and the second in mid-July.
The first run fish are headed directly for the Russian River, a small clear-water tributary of the Kenai River, and represents the smaller of the two runs with an annual return of 30, fish.

The Kenai River is unique, with its rugged undeveloped catchment, its strong influence of lakes and glaciers, and its low-elevation wetlands, all within the Kenai Peninsula.
It is also the most important sport fishing river in Alaska, with many fishermen seeking out the mighty king (chinook) salmon because of the size reached in the Kenai River. Recent analyses indicate that Yukon River Chinook Salmon stocks appear to be in the 8th year of a mul-ti-year period of low productivity.
Historically, the Yukon River Chinook Salmon stocks showed periods of above-average abundance () and periods of below-average abundance ( onwards), as. adult return vs.
the previous year’s total jack return for each of the years The correlation is strong for spring chinook, but less for fall chinook (r2 = and respectively). The arrival distribution is taken as the historic daily mean scaled to produce the correct total run-size.
Guest editorial, Dec. 16, ‘Pave paradise’ not the answer for Kasilof River. With the rise of personal-use salmon fishing at the mouths of the Kenai and Kasilof Rivers, we, who live here, can expect the convoys of dip-netters to break camp in Anchorage and the Valley and head south in July.

Results confirmed that an early run entered the river in May and June and spawned in tributaries, and a late run entered the river from late June through August and spawned.On June 7,we published a temporary deviation entitled Drawbridge Operation Regulation; Snohomish River and Steamboat Slough, Everett and Marysville, WA, in the Federal Register (83 FR ).
