| Abstract: | A semi-quantitative assay is described for assessing the effectiveness of bait extracts for the lobster Homarus gammarus (L.), using an extract of the squid Loligo vulgaris
Lamarck as a standard. Fractionation of this extract indicated that, while no single component was as attractive to lobsters as the whole, the recombination of the various components yielded a solution which was as attractive as the original extract. It appears likely that several different classes of chemosensory cell must be simultaneously stimulated for the initiation of feeding behaviour in the lobster. |
