PERCENTAGE OF CATCH 



FIGURE 4.— Percentage of catch of 1961- to 1964-brood fall 

 Chinook salmon from Kalama River hatcheries taken by area 

 and fishery, 1963-69. Percentages do not add to 100% due to 

 rounding. 



Elokomin and OxBow Hatcheries, 

 1961 Brood 



A portion of the 1961-brood fall chinook salmon 

 productions at Elokomin and OxBow Hatcheries 

 were given special marks. At Elokomin Hatchery, 

 480,500 or 30% of the production was LV-RM clip- 

 ped. Approximately 450,400 or 10% of OxBow's 

 fall chinook salmon production was marked with a 

 RV-RM clip. These fish contributed to the fisheries 

 from 1963 through 1966. 



During the 4 yr, 235 Elokomin and 336 OxBow 

 fish with special marks \yere estimated to have 

 been caught (Table 10). Chinook salmon from both 

 hatcheries were taken primarily as 3-yr-olds. A 

 larger portion of Elokomin fish than OxBow fish 

 were taken as 4-yT-olds, and a larger portion of 

 OxBow than Elokomin fish were taken as 2- and 

 5-yr-olds. Potential contributions were estimated 

 at 2,000 and 8,500 fish for Elokomin and OxBow 

 respectively. The catch per 1,000 fish released at 

 Elokomin Hatchery was 1.3 fish and at OxBow 1.9 

 fish. The catches per pound of fish released at 

 Elokomin and OxBow Hatcheries were 0.2 and 0.4 

 fish respectively. 



About one-half of the catch from the two hatch-
