[0109] Among the above compounds, AF-024, AF-034, AF-035, and AF-048 are reported to have concentrations corresponding to the 50% adhesion inhibition rate to Barnacle (EC.sub.50) of 0.054, 0.0084, 0.03, and 0.019 g/ml, respectively. The EC.sub.50S of the remaining compounds are still not known. AF-034, AF-035, and AF-048 were used as comparative examples for describing effects in actual ocean tests since they had lower EC.sub.50 values than that of AF-024.
