Abstract
    Several artificial baits were developed and compared favourably with natural baits. The effectiveness of all baits was related to the rate of diffusion of attractant chemicals from the insoluble material into the environment. The most efficient artificial baits were prepared by incorporating either an extract of whole sprats, Sprattus sprattus, or a mixture of pure attractant chemicals into the matrix of a solid block of calcium sulphate dihydrate (plaster of Paris). The rate of release of the attractants and hence the effectiveness of the artificial bait was found to be critically dependent on the crystalline form of the calcium sulphate block.
