The Alaska Department of Fish and Game, Division of Sport Fish, is currently assessing the harvest of selected wild stocks of chinook salmon Oncorhynchus tshawytscha by an expanding mixed-stock marine sport fishery in Cook Inlet. Chinook salmon stocks in the Kenai River and Deep Creek are being assessed using a coded wire tag marking and recovery program. Two rotary smolt traps were used to capture 7,018 chinook salmon smolt in the Kenai River delta during 1996. A total of 6,538 smolt, or 6% of the tagging goal, was marked and released. Chinook salmon smolt were present in the Kenai River delta throughout the summer with peak catches in June. We also marked and released 8,966 chinook salmon and 4,868 coho salmon Oncorhynchus kisutch smolt in Deep Creek in 1996. The number of chinook salmon smolt marked using one rotary screw trap was 24% of our goal. Chinook salmon smolt were present in lower Deep Creek throughout the summer with peak numbers emigrating between mid-June and mid-July. Two age-classes of smolt (age 0 and 1) were present in Deep Creek catches. We estimated the proportion of chinook salmon marked with coded wire tags in previous years by examining adult fish in the inriver escapements. We could not estimate the proportion of Kenai River chinook salmon marked as fry in 1993 because we found no tagged adults in the approximately 1,800 chinook salmon examined. Examination of chinook salmon adults from Deep Creek for adipose fin clips revealed that 14.1% (SE=3.5%) of the fish present in the lower river during sampling were strays from hatchery releases in the adjacent Ninilchik River, and 7.2% (SE=2.0%) were marked in 1994 in Deep Creek. In 1996, we also captured adult coho salmon in Deep Creek and found that 27.8% (SE = 3.1%) were tagged as smolt in 1995. The proportion of marked adults captured did not change over time, and the marked proportion was used to estimate that 34,351 (SE = 3,779) coho salmon smolt emigrated from Deep Creek in 1995.

Recovery of Coded-Wire Tags from Chinook Salmon in California's Central Valley Escapement and Ocean Harvest in presents important data for the improvement of Central Valley salmon management. Until , only experimental releases of fall-run Chinook salmon from Central Valley hatcheries were marked and coded-wire tagged (low. The percentage of Chinook salmon that were released as tagged (CWT) and associated untagged juveniles was as high as 42% in the San Joaquin Basin fall-run Chinook salmon escapements and 65% in the Sacramento River Basin fall-run Chinook salmon escapements during fall , primarily as a result of increased tagging efforts. A mean of.

Currently, sport fishing for Chinook salmon in the Eklutna Tailrace is a popular recreational activity. This is a terminal fishery, and all returning Chinook salmon will be harvested. The Chinook salmon broodstock source for Eklutna Coded wire tagging of coho and chinook salmon in the Kenai River and Deep Creek is Ship Creek origin.

An awesome day of fishing for Coho Salmon on the Lower Kenai River. These beautiful fish are an absolute blast to catch. Gary the owner of Alaska Fish On Charters has this river Dialed in and will. U.S. wild-caught Chinook salmon is a smart seafood choice because it is sustainably managed and responsibly harvested under U.S.

In this episode we're kicking off our time near Petersburg by chasing an Alaskan icon: king (Chinook) salmon. We've never fished for this species before, so. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): The current run of Columbia River summer Chinook produced in areas upstream of Priest Rapids Dam is descended from the Chinook populations that were blocked by construction of Grand Coulee Dam in The Grand Coulee Fish Maintenance Project was a federally funded program that was intended to relocate salmon.
Harvest, Age, and Size at Age of Chinook and Coho Salmon at Strawberry Creek Weir and Besadny Anadromous Fisheries Facility Size at age 1+ and age 2+ for coded wire tag (CWT) chinook salmon at SCW was up in the fall of Age 1+ fish (all males) were the largest (length and weight) since these statistics have chinook and coho for.
Chinook salmon tagging for the recent multistate project began in and the analysis involved s coded wire tags recovered from harvested fish.
Results of the analysis show the fish stocked by Wisconsin DNR appear to survive at better than average rates and account for a comparatively large percentage of the stocked chinook salmon.
Around the town of Seward, Alaska and Kenai Fjords National Park we are often called "the fish scientists" or just "the coho crew." The three of us (James, Andrew, &Tim) came from Lake Clark National Park to Kenai Fjords to learn all that we can about coho salmon in the Resurrection River. It used to be common to find Chinook salmon 40 inches or more in length, particularly in the Columbia River or Alaska’s Kenai Peninsula and Copper River regions.
The reductions in size could have a long-term impact on the abundance of Chinook salmon, because smaller females carry fewer eggs, so over time the number of fish that hatch and. Most people consider king salmon, also known as Chinook salmon (Oncorhynchus tshawytscha), the finest of the wild Pacific salmon is known for its high content of healthy omega-3 oils and its big taste.
A decadent item to feature at a white tablecloth, candlelit dinner, king salmon is about as good as it gets. Yellow Spots on Chinook and Coho Salmon Anglers often notice distinct yellow marks that are circular in shape and are often found on the belly near the pelvic fins.
Because fisheries professionals use artificial dyes or ink to mark fish, these circular-yellow marks found on Great Lakes Chinook salmon are often misidentified as an artificial mark. Idaho Fish and Game, whose mission is to preserve, protect, perpetuate, and manage all wildlife in Idaho.

Throughout the season, tag retention studies were conducted for fall and spring-run Chinook and coho salmon to determine actual marking/tagging rates for each coded-wire tag code. Approximately marked/tagged fish per tag code were retained and held separately for a period of approximately 21 days following the completion of each tag code.Coho salmon (Oncorhynchus kisutch (Walbaum)) also called silver salmon, are found in coastal waters of Alaska from Southeast to Point Hope on the Chukchi Sea and in the Yukon River to the Alaska-Yukon border.
Coho are extremely adaptable and occur in nearly all accessible bodies of fresh water-from large transboundary watersheds to small tributaries. General description. Coho are on the move this time of year; so don’t spend a lot of time fishing where they may have been yesterday or last week.
Stay on the move until you find fish. There’s a better-than-even chance that yesterday’s productive spot won’t be productive today, and you may have to prospect for new places to fish every day.
