Duringthe Apollo 7 flight, BCF's "Oregon II" released Rhodamine B dyes and fish oils into the Yucatan Channel, It was part of a program to evaluate observations made from space. The observations may prove useful in detecting and assessing fish schools, A Coast Guard plane flying between 400 and 10,000 feet photographed the waters in which the dyes and oils were released. These photos will be compared with those taken from the Apollo spacecraft. La Jolla's 'Advisories' Benefit Fishermen The Fishery-Oceanography Center at La Jolla, Calif., continued in September its suc- cessful daily albacore fishing information broadcasts and 15-day bulletin series.
