Abstract
Recruitment of larvae of the gastropod mollusc, Haliotis rufescens, has been shown to be induced by algal molecules which are uniquely available at the surfaces of crustose red algae, including species of Lithothamnium, Lithophyllum and Hildenbrandia (Morse & Morse 1984). Molecules inducing settlement and metamorphosis of these abalone larvae can be solubilized and extracted from algal homogenates (Morse, et al l979b; Morse & Morse 1984). Similar inducers were also found in cell-free extracts of a number of red marine macroalgae, including crustose species from the Atlantic and Pacific, articulate coralline algae, and foliose red algae (Morse & Morse 1984). Preliminary analyses of the amino acid composition of hydrolysates of an active extract from crustose algae suggested the presence of amino acids structurally related to GABA (Morse, et al 1979a). It was found that GABA and several of its analogs are potent inducers of larval settlement and metamorphosis.
