Salmon National Fish Hatchery 1964-brood fish. 

 Both groups contributed to the fisheries from 1966 

 through 1969. 



The estimated catches of special marked fish 

 from Bonneville and Little White Salmon Hatch- 

 eries were 762 and 303 fish respectively. Sig- 

 nificant numbers of Bonneville special mark 



chinook salmon were caught in the ocean fisheries 

 as 2-, 3-, and 4-yr-olds, while the Little White fish 

 contributed as 3's and 4's (Table 13). The largest 

 numbers of both hatcheries' fish were taken in the 

 ocean commercial fisheries. 



The potential contributions for Bonneville and 

 Little White were 27,100 and 11,000 fish, respec- 

 tively. Bonneville produced 2.7 fish per 1,000 or 

 0.4 fish per pound of fish released. Little White 

 produced 1.3 fish per 1,000 or 0.2 fish per pound of 

 fish released. 



The distribution of the Bonneville Hatchery 

 catch was more southerly than that of Little White 

 Salmon Hatchery (Figure 8). Nearly 50% of the 

 catch from both facilities occurred in the 

 Washington fisheries. The British Columbia 

 fisheries took most of the remaining Little White 

 catch (41%). 



Common Mark Catch and 



Potential Contribution All Study 



Facilities Combined, 1961-64 Broods 



An Ad-M common mark was applied to a portion 

 of the 1961-64-brood fall chinook salmon produc- 

 tion at all 13 study facilities. The RM was clipped 

 from the 1961- and 1963-brood fish, and the LM 

 was clipped from the 1962- and 1964-brood 

 chinook salmon. Common marks were applied to 

 21,320,000 (approximately 10%) of the 

 213,014,000 fall chinook salmon released over the 

 four brood years from the 13 study facilities. 



We estimated 65,620 common marked fish were 

 caught from 1963 through 1969 (Table 14). On the 

 average over the four broods 76% of the common 

 marked fish were taken in the ocean, with 56% 

 caught in the ocean commercial fisheries. In the
