Book Description
In 2010, the total number of Chinook salmon counted at the Ninilchik River weir was 658 fish, of which 623 were wild and 35 were hatchery-reared. The wild Chinook salmon escapement corresponding to the sustainable escapement goal (SEG) index monitoring period (3 July through 31 July) was 605 fish, which fell within the SEG range of 550-1,300 fish. Based on the dates of the median run times during the SEG index monitoring period, the wild Chinook salmon run was 8 days earlier than the hatchery-reared Chinook salmon run. The dominant age class was ocean age 2 for both wild and hatchery-reared Chinook salmon. No egg takes were conducted in 2010. Stocking goals were met for the Ninilchik River and all Kachemak Bay terminal saltwater fishery locations. The Ninilchik River Chinook salmon supplementation program has continued to provide sport fishing opportunities on the Ninilchik River and terminal saltwater fisheries. Continuation of Chinook salmon assessment at the Ninilchik River weir is recommended to ensure that adequate escapement of wild Chinook salmon is maintained.

Book Description
During 2005, wild (naturally-produced) and hatchery-reared Chinook salmon, Oncorhynchus tshawytscha, runs to the Ninilchik River were assessed with a weir to determine the stock composition of total escapements. The Ninilchik River Chinook salmon supplementation program has provided important sport fishing opportunities on the Ninilchik River and terminal fisheries. Continuation of the Chinook salmon assessment at Ninilchik River weir is recommended to insure that adequate escapement of wild Chinook salmon is maintained.

Book Description
From July 3-31, 2009, wild (naturally-produced) and hatchery-reared Chinook salmon, Oncorhynchus tshawytscha, runs to the Ninilchik River were assessed with a weir to determine the stock composition of total escapements. The Ninilchik River Chinook salmon supplementation program has provided important sport fishing opportunities for the Ninilchik River and terminal saltwater fisheries. Continuation of the Chinook salmon assessment at Ninilchik River weir is recommended to ensure that adequate escapement of wild Chinook salmon is maintained.

Book Description
The Ninilchik River contains both wild and hatchery-reared runs of Chinook salmon. In 2011-2015, the wild Chinook salmon escapements corresponding to the sustainable escapement goal (SEG) index monitoring period (3-31 July) fell within the SEG range of 550-1,300 fish every year. Above-average runs of hatchery-reared Chinook salmon occurred in 2014 and 2015. Based on the median run-timing date during the SEG index monitoring period, the 2011-2015 wild and hatchery-reared Chinook salmon runs to the weir had variable run timing between years and between one another. During each year from 2011 through 2015, the predominant age class for the wild run to the weir was ocean age 2 or 3, and the predominant age class for hatchery-reared fish was ocean age 1. Although Ninilchik River egg-take goals were not achieved in 2012-2015, stocking goals were met in all years for the Ninilchik River and all Kachemak Bay terminal saltwater fishery locations with additional contributions from broodstock collections at Crooked and Ship Creeks. Starting in 2012, all smolt were reared in the William Jack Hernandez Sport Fish Hatchery in Anchorage and stocked at age 0. In 2015, the Ninilchik River stocking goal was increased to 150,000 smolt annually to provide more inriver sport fishing opportunity and better support broodstock collection. Adaptive stocking methods were used at the Nick Dudiak Fishing Lagoon on the Homer Spit to avoid mortality associated with the diatom Chaetoceros spp.

Book Description
During 2004, wild (naturally-produced) and hatchery-reared Chinook salmon, Oncorhynchus tshawytscha, runs to the Ninilchik River were assessed with a weir to determine the stock composition of total escapements. This report examines the results of this study.

Book Description
During 2002 and 2003, wild (naturally-produced) and stocked Chinook salmon, Oncorhynchus tshawytscha, runs to the Ninilchik River were assessed with a weir to determine the stock composition of total escapements and to determine if Chinook salmon stray to the Ninilchik River from three stocking locations in Kachemak Bay. This report examines the results of this study.

Book Description
During 1999 and 2000 naturally-produced and hatchery-produced chinook salmon, Oncorhynchus tshawytscha, returns to the Ninilchik River were assessed with a weir to determine the age and sex compositions of total escapements and to estimate the contribution of chinook salmon that stray to the Ninilchik River from three Kachemak Bay chinook salmon enhancement locations. Additionally during 2000, a random sample of sport harvested Chinook salmon were examined for an adipose finclip to estimate the stock composition of the harvest sampled each weekend in the Ninilchik River below the Sterling Highway. This report examines the results of these studies.
