However, we coordinate aspects of this survey with the striped bass and sturgeon tag-recovery survey being conducted in the Sacramento-San Joaquin Delta (SFRA grant F-51-R, project: #71: Bay-Delta Sport Fish Resource Assessment Project - Striped Bass) to assist with respective project objectives. The Central Valley Angler Survey also provides an estimate of Chinook salmon harvest in the Central Valley recreational fishery. This estimate complements Chinook salmon harvest estimates for California ocean commercial and recreational fisheries generated by CDFG’s Ocean Salmon Project. Combined, these estimates are used by the Pacific Fishery Management Council to forecast Chinook salmon harvest quotas in ocean waters off the coasts of Washington, Oregon, and California. The inland recreational harvest component, for Chinook salmon of both hatchery and wild origin, has been lacking throughout most of the management history of Chinook salmon fisheries supported by the Central Valley.

Fish and Wildlife Service in August of 1947 to learn something of the population readjustments among the game fishes and interrelated species [since the construction of the Shasta Dam], and to determine the extent and value of the sports fishery dependent on these fish populations. An effort was also made to arrive at some method of sampling to obtain accurate estimates of the sports fishing effort and catch. The area studied extends from Keswick Dam to Chico Creek and is referred to in this report as the Upper Sacramento River.33182:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=33182Fri, 24 Jun 2011 08:01:21 -07001950-01-01T00:00:00CalFishCalFish collection.

This report has been prepared as supportive documentation required for implementation of Public Law 102-575, the Central Valley Project Improvement Act (CVPIA) passed by Congress and signed into law by the President on October 30, 1992. The CVPIA requires the Secretary of the Interior to implement a program which makes all reasonable efforts to ensure that, by the year 2002, natural production of anadromous fish in Central Valley rivers and streams will be sustainable, on a long-term basis, at levels not less than twice the average levels attained during the 25-year period of 1967- 1991. Anadromous sport fish species using the rivers and streams of California's Central Valley include: Chinook salmon (Oncorhynchus tshawytscha), steelhead trout (O. mykiss), sturgeon (Acipenser ssp.), striped bass (Roccus saxatilis), and American shad (Alosa sapidissima). Virtually all anadromous fishes populations in the Central Valley of California have exhibited significant declines from 1967 through 1991. The major losses in the populations have been primarily from the naturally reproducing components. These declines are recognized as partially the result of water management activities, as well as habitat degradation, poor water quality, and catastrophic natural events.33181:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=33181Fri, 24 Jun 2011 08:01:18 -07001994-01-01T00:00:00CalFishCalFish collection. Contact cshannon@dfg.ca.gov for assistance. - In October 1992, the Central Valley Project Improvement Act (CVPIA) was signed into law. One objective of the CVPIA 1s to restore the abundance of natural fish stocks in Central Valley rivers and streams. To achieve this objective, the CVPIA requires the development of restoration actions that ensure sustainable, long-term populations of native anadromous fish stocks. Section 3406(b)(16) of the CVPIA specifies the development of a monitoring and assessment program to evaluate the effectiveness of implemented restoration actions. The Comprehensive Assessment and Monitoring Program (CAMP) was established for this purpose. The CAMP program recommends monitoring of both adult and juvenile fish populations. It was recommended that adult monitoring include spawner returns (escapement) as well as in-river recreational, ocean recreational and commercial harvest estimates. In 1998, the California Department of Fish and Game (CDFG) began the Central Valley Salmon and Steelhead Harvest Monitoring Project to help enumerate the number of adult Chinook salmon and steelhead resulting from natural production in Central Valley rivers and streams. This long-term harvest monitoring project will determine annual estimates of the total in-river harvest. In addition, this project will provide limited harvest data of other anadromous and resident sport fish species. In 2000, the third year of the project, the Department conducted an angler survey on the Sacramento River and six major tributaries between January 1st and December 31st, 2000. A total of 51,564 anglers was surveyed who spent an estimated 3,531,081 angler-hours sport fishing. Chinook salmon was the target of most anglers surveyed, anglers expended 1,468,269 angler-hours in pursuit of this species. Striped bass was the second most sought species with 1,155,012 angler-hours expended. Anglers also spent 108,672 angler hours in pursuit of steelhead trout. Anglers targeting Chinook salmon harvested an estimated 70,829 salmon. Angler's targeting striped bass harvested an estimated 59,704 striped bass. While anglers targeting steelhead trout reported keeping few fish, this survey estimates that 1,014 steelhead were harvested.32816:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=32816Fri, 24 Jun 2011 07:57:38 -07002001-01-01T00:00:00CalFishCalFish collection.

A total of 55,471 anglers was surveyed who spent an estimated 3,847,078 angler hours sport fishing. Chinook salmon was the target of most anglers surveyed; anglers expended 1,526,978 angler-hours in pursuit of this species. Striped bass was the second most sought species with 1,256,990 angler-hours expended. Anglers also spent 108,932 angler-hours in pursuit of steelhead trout. Anglers targeting Chinook salmon harvested an estimated 93,150 salmon. Angler's targeting striped bass harvested an estimated 71,830 striped bass. While anglers targeting steelhead trout reported keeping few fish, this survey estimates that 886 steelhead were harvested.32815:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=32815Fri, 24 Jun 2011 07:57:37 -07002001-01-01T00:00:00CalFishCalFish collection. Contact cshannon@dfg.ca.gov for assistance. - The California Department of Fish and Game conducted an angler survey on the Sacramento River and six major tributaries between April and December 1998. The purpose of the survey was to estimate the in-river effort and harvest of nine sport fish species. Thirty eight thousand nine hundred twenty-two anglers were surveyed and they spent an estimated 3,079,837 angler-hours sport fishing. Chinook salmon was the target of most anglers, having expended 1,330,017 angler-hours in pursuit of this species. Striped bass was the second most sought species with 1,141,327 angler-hours expended targeting this species. The most common fish in angler's creel was Chinook salmon. Anglers harvested an estimated 84,181 Chinook salmon. Striped bass and catfish were also abundant in anglers' creel. Anglers harvested an estimated 83,503 striped bass and 66,372 catfish.32814:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=32814Fri, 24 Jun 2011 07:57:33 -07001999-01-01T00:00:00CalFishCalFish collection.

The CVPIA calls for the development of restoration actions that ensure long-term sustainable populations of native anadromous fish stocks. To evaluate the effectiveness of restoration actions, the Comprehensive Assessment and Monitoring Program (CAMP) was developed under Section 3406(b(16) of the CVPIA. To assist in the CAMP monitoring program, the California Department of Fish and Game (DFG) developed the Central Valley Salmon and Steelhead Harvest Monitoring Project. The DFG has used angler surveys in the past to monitor the harvest of anadromous fish within Central Valley Rivers and streams. Unfortunately, no comprehensive or long-term (more than 5 years) surveys have been made on a consistent basis, This project is designed as a long-term monitoring program to determine annual estimates of total in-river harvest of sport fish from the Sacramento River and major tributaries. Also, the data will complement and enhance other ongoing DFG harvest monitoring programs such as Department's adult striped bass, adult sturgeon, and ocean salmon harvest. This project originated in April, 1998 and is into its fourth year.32798:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=32798Fri, 24 Jun 2011 07:57:11 -07002002-01-01T00:00:00CalFishCalFish collection. Contact cshannon@dfg.ca.gov for assistance. - The Marine Resources Branch conducted a salmon sport catch census in the Central Valley during the 1964-65 season. A steelhead sport catch census was conducted on the Sacramento River. Sampling was conducted on a predetermined, systematic pattern. The major part of the Sacramento River salmon sport catch was landed at 50 fishing resorts and 10 public boat launching ramps in the Keswick Dam - Clarksburg area. All of these resorts and ramps, plus five major bank fishing sites, were included in the census. The number of salmon and steelhead landed each month was the sum of landings reported by all resort operators, plus estimates of landings at boat ramps and bank fishing sites sampled. Angling effort and success was obtained by sampling at public boat ramps, bank fishing sites and fishing resorts (October û November). Sacramento River salmon landings were 15,800 fish, including 9,980 fall-run and 5820 winter and spring -run salmon. There were 72,400 angler-days spent in pursuit of salmon. Estimated fall-run salmon landings in other streams included in the census were as follows: Feather River; 865 American River; 170 Mokelumne River; 80 San Joaquin River; 25 Spring-run salmon landings in Butte Creek were 270 fish. Sacramento River adult steelhead landings were 15,470 fish. There were 74,450 angler days spent in pursuit of steelhead.32528:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=32528Fri, 24 Jun 2011 07:55:17 -07001966-01-01T00:00:00ChinookReports - This report covers the 49th annual inventory of Chinook salmon, Oncorhynchus tshawytscha, spawner populations in the Sacramento-San Joaquin River system, It is a compilation of sources estimating the late-fall-, winter-, spring-, and fall-run populations for streams which were surveyed.
