between the river systems. Marked coho are released, also, above and below suspected en- 

 vironmental "blocks" in the Grays Harbor Estuary to measure how the blocks affect fish 

 emigration through such areas.

Early marine life history - chum and pink salmon - Visual observations, beach seine, and 

 traps were used to obtain information on distribution and abundance of pink and chum 

 salmon fry in Puget Sound estuaries. A technique for mass marking of salmon fry with 

 fluorescent dyes was investigated. 



Washington 1-30-R Earle D. Jewell Completed 1968 



Field recovery coded wire tag - This study has improved magnetic detectors for recovery of 

 coho salmon marked by coded wire tag and developed tools and techniques to ijnprove tag ex- 

 traction. Field recovery tests have been conducted over a broad range of conditions in 

 Puget Sound.

Hatchery coho salmon— contribution to the fishery - As part of a hatchery evaliiation program, 

 the Washington Department of Fisheries released fin-clipped snolt coho salmon at 22 hatcheries 

 on tributaries to Puget Sound and Columbia River. Stations participating in the evaluation 

 program mark about 10 percent of their yearling production. Marked adult fish are re- 

 captured at the hatchery racks by the hatchery personnel. 



Washington 1-33-D Richard E. Noble $32,000 



Evaluation of dry feed for hatchery salmon - Dry fish feeds formulated from raw materials, 

 including nonfood fish and kelp, as well as byproducts from milling and other food production, 

 are tested and evaluated for hatchery-reared sfilmon. 



Washington 1-37-R Peter K. Bergman Completed 1968 



Analysis and publication of coded wire tag research data - Data on reteation of coded wire 

 fish tags are processed, and the information placed on data processing cards. Preliminary 

 analyses are performed on most aspects of the study. 



Washington 1-40-R Ray C. Johnson $22,000 



Larval and estuarial studies - pink and chum salmon populations - Egg and preemergent fry 

 are sampled in Puget Sound streams and rivers to assess survival of chum salmon 

 alevins to the swim-up stage. Density and abundance of the fry provide information for the 

 prediction of the size of the adult run. 



Washington AFC-12 Earle D. Jewell Completed 1968 



Port Susan-Port Gardner pink salmon st udies - During August and September 1967, 3,201 pink 

 salmon were marked with Petersen disc tags and released in the Puget Sound (Port Susan-Port 

 Gardner) commercial fishery near Everett. Tags from 657 recaptures were returned. Returns 

 are analyzed to provide information on the origin, timing, and movement of the marked fish.

Measurement of spawning success and fry quality of chum salmon utilizing natural and con- 

 t rolled spawning areas in Big Beef Creek. Washington - A spawning channel is developed by 

 modifying a small stream located at the University of Washington's Fisheries Research 

 Institute station on Big Beef Creek about 2.5 miles north of Seabeck on Hood Canal in 

 Kitsap County. It provides controlled conditions for studies of the survival rate amd 

 quality of salmon from egg deposition to emergence in areas where the ecological conditions 

 of the spawning beds have been manipulated. 



Washington AFG-U Earle D. Jewell $27,000 



Gill net drop out study - Objectives of the original projects were, first, to determine the 

 rate of salmon dropout for gill nets of various sized mesh and survival of sslmon that 

 escape gill nets, and, second, to develop a net to reduce such dropout. Only the first 

 objective is accomplished for Chinook and coho salmon in the Puget Sound fishery.
