PERCENTAGE OF CATCH 



Figure 6.— Percentage of catch or 1962-brood fall chinook 

 salmon from Grays River and Cascade Hatcheries taken by area 

 and fishery, 1964-67. Percentages do not add to 100% due to 

 rounding. 



itat Hatchery. At Big Creek Hatchery nearly 30% 

 or 580,000 1963-brood chinook salmon were given 

 RV-RM special clips. These fish contributed to the 

 fisheries from 1965 through 1968. 



The estimated catches of chinook salmon with 

 special marks from Klickitat and Big Creek 

 Hatcheries were 1,858 and 914 fish, respectively 



196 



(Table 12). The Klickitat fish were caught primar- 

 ily as 3- and 4-yr-olds, except in the ocean sport 

 fishery where 2-yr-olds were predominant. In the 

 marine commercial and Columbia River fisheries, 

 the predominant age class was 3-yr-olds. Nearly 

 60% of Big Creek's special marked fish were 

 caught in their third year of life, and about one- 

 third were taken as 4-yr-olds. 



Klickitat and Big Creek Hatcheries' potential 

 contributions to the fisheries were 42,500 and 

 12,900 fish, respectively. From Klickitat the con- 

 tribution was 14.7 fish per 1,000 released and 2.2 

 fish for each pound of fish released. The contribu- 

 tion per 1,000 chinook salmon released at Big 

 Creek was 6.5 fish and 0.7 fish for each pound of 

 fish released. 



Distribution of both facilities' catches can be 

 compared by examination of Figure 7. Thirty-nine 

 percent of Klickitat's fish were taken in the 

 British Columbia commercial fisheries compared 

 with 16% for Big Creek, suggesting a more north- 

 erly distribution for Klickitat fish. Although Big 

 Creek fish pass through only a small portion of the 

 Columbia River commercial fishery, the portion 

 taken in this fishery is larger (19%) than the 

 Klickitat portion (10%). Over half of Big Creek's 

 estimated catch was taken in the Washington 

 marine fisheries. 



Bonneville and Little 



White Salmon Hatcheries, 



1964 Brood 



About 10% (957,100) of the 1964-brood Bon- 

 neville Hatchery fall chinook salmon were 

 marked with a LV-LM clip. The RV-LM mark was 

 applied to about 10% (797,300) of the Little White
