The sportsmen's groups pay for the food fed to the young steelhead during the year that they spend at Coleman Station. planted Fish Returns A total of 378,514 marked yearling steelhead was planted into the Sacramento River during the bien- nium, including 227,113 in 1957 and 151,401 in 1958. Since its inception, the project has marked and re- leased 1,041,754 yearling steelhead. Hatchery fish made up approximately 17 percent of the entire run of adult steelhead into the upper Sacramento River system in 1956 and 14 percent in 1957. COASTAL STREAMS STUDIES During the biennium, a total of 209,439 hatchery- reared steelhead was marked and released from the Cedar Creek Experimental Station, in order to provide data with w^hich to evaluate the potentiality of hatch- eries to improve runs of steelhead in the north coastal streams. The specific information which present ex- periments are designed to yield is: (1) The size at which young steelhead should be released for maximum returns; (2) Relative returns from releases made in upstream and downstream areas; and (3) Possible diff^erences in returns from different strains of steelhead. The 1957 crop of steelhead totaled 63,609, which were divided into four marked groups for release. They varied in size from to per pound. Half of each of these size groups were released into the South Fork of the Eel River at Cedar Creek, and the other half were released at Fortuna near the mouth of the river. All of these fish were from eggs taken at the Snow Mountain egg collecting station on
