FORTY-THIRD BIENNIAL REPORT 73 tagged and released. On one of these cruises mangrove seeds were brought back and planted in Salton Sea, one phase of the plan for developing a sport fishery in this inland body of salt water. Two cruises in Central California waters resulted in the development of a mid-depth trawl that can be operated from a single vessel. Shrimp populations in the area were also assessed and this fishery given addi- tional stimulus. One other trip made in connection with the trawl studies extended to the coastal waters of Washington and comprised assessments of bottom fish populations off Central and Northern California and Oregon and Washington. Yelloivfiv: Although the work of the Yelloivfin was not as varied as that of the N. B. ScofieUi, this vessel kept equally busy, spending 373 days at sea during the biennium. In the fall of 1952 she made four cruises along the coast of Baja California waters and three in the fall of 1953. On these trips, covering the area be- tween Magdalena Bay, latitude 25 degrees N. and Pt. Reyes, latitude 38 degrees N., a census was taken of the abundance of sardines. Pacific and jack mackerel and anchovies, and of the relative numbers of the year class of sardines resulting from the previous spring spawning, when these fish were about six months old. One of the outstanding accomplishments resulting from the work aboard the Yelloivfin has been the de- velopment in the past year of a blanket net for the rapid and efficient collection of fish samples. This net and its successful operation resulted from the ingenu- ity and industry of the vessel crew and illustrates the importance of the contributions that every member of the staff makes to the department's marine research programs.
