Minimum effective release rate of antifoulants. 2. Effects of TBTCI, 2-furyl-n-pentyl ketone and coumaric acid at Snug harbor, Hawaii.
Minimum effective release rate (MERR) of three antifoulants was examined at Snug harbor, Hawaii using a dynamic diffusion system. Among the three antifoulants tested TBTCI was found to be effective in preventing the settlement of Hydroides elegans and Crisea sp at 0.5 microg cm(-2) d(-1) flux rate. At a maximum flux rate of 10 microg cm(-2) d(-1) of 2-furyl-n-pentyl ketone larval settlement of both the test species were 32-36% reduced. More or less similar effect was seen at 10 microg cm(-2) d(-1) of coumaric acid. Non-toxic antifoulants, 2-furyl-n-pentyl ketone and coumaric acid exhibit specific activity against target species. MERR obtainedfor the three antifoulants is discussed.
