REARING BARNACLE CYPRIDS IN THE LABORATORY FOR MARINE FOULING STUDIES
Abstract
Studies of marine fouling and evaluations of antifouling coatings and methods have been carried on at field stations under naturally occurring conditions. A more aggressive, fundamental study of the marine-fouling problem can be attempted, and evaluations of antifouling materials can be accomplished with greater speed and regularity, if studies employing live marine organisms are conducted under laboratory-controlled conditions. The techniques which, for the first time, succeeded in the laboratory mass-rearing of four species of acorn barnacles indigenous to the U.S. Atlantic coastline are set forth. The methods for removal of embryos from parent barnacles, feeding, and maintenance of proper environment for larval stages are described. Methods are described by which fertile barnacle ova are hatched, and metamorphose with successive ecdyses through six free-swimming naupliar stages, to the swimming-and-crawling cyprid stage. Photomicrographs of barnacle embryos, the six naupliar larval stages, and the presettled cyprid larval stage are presented. The future capabilities of this laboratory methodology and its anticipated contribution toward the development of improved antifouling materials are discussed.
