Antennular chemosensitivity in the Spiny lobster,panulirus argus:Amino acids as feeding stimuli

Abstract

Antennular chemosensitivity in the spiny lobster, Panulirus argus, to extract of the pink shrimp, Penaeus duorarum is based on extract components of less than 1,000 molecular weight. Amino acids account for a major part, but not all, of the extract's capacity to stimulate antennular receptors. Taurine is the most stimulatory of the amino acids comprising P. duorarum extract, although no single amino acid accounts for the amino acid fraction's stimulatory potential.
