The present invention relates to derivatives of &#x3b1;, &#x3b1;-disubstituted amide compounds which comprise a substituted aryl at the &#x3b1; carbon such that the substituent provides a means for attachment or incorporation of the compound to or in a polymer. The provision of such a substituent on the aryl has surprisingly been found not only to permit attachment to or incorporation n a polymer but also retention of useful antifouling activity. In embodiments, the substituent is selected from hydroxyl, ethers, esters, carboxyls, alkylsilyls and alkenyls. Experiments demonstrate that antifouling activity can be as good or better as the corresponding unsubstituted compound and that polymers functionalized so as to include or be formed from the substituted compound can be used to reduce settlement.

Anti-fouling compound and method of use

The gustatory additive of the present invention provides an improved fish bait. The gustatory additive causes a fish to hold a lure treated with the gustatory additive in its mouth for a longer period of time or causes the fish to swallow the lure. Because the fish holds the lure coated with the gustatory additive in its mouth for a relatively longer period of time, the fisherman has more time in which to set the hook in the fish's mouth. The gustatory additive of the present invention is comprised of a mixture of nutrients that are mixed with a water insoluble matrix and then applied to the surface of a lure. The gustatory additive of the present invention can also be distributed throughout the lure.
