Chemoreception in Decapod Crustacea and Chemical Feeding Stimulants as Potential Feed Additives

Types of chemical feeding effectors are listed, and locations and functions of decapod chemoreceptors are discussed. Low molecular weight substances found most stimulatory in behavioral, physiological, and electrophysiological studies on decapods are tabulated. Most of these chemicals have not been widely tested, and some are prohibitively expensive for use in feeds. The most generally stimulatory single substances are L‐glutamic acid, glycine, and taurine. Mixtures of substances can be more effective than single substances; e.g., the use of betaine plus amino acids shows some promise.
