    Abstract

    The crude GABA (ã- amino butyric acid) extracted from Hypnea valentiae collected from Vizhinjam coast was tested for its activity of favouring settlement of pediveliger larvae of Perna viridis by comparing the similar activity of standard commercial grade GABA. The results showed better rate of settlement in 10 ppm followed by 15 ppm standard GABA (100% in 10 ppm and 83.3 % in 15 ppm standard GABA) against only 55 % in both 10 and 15 ppm of crude GABA extracted from the seaweed, whereas the control showed 20.73 % of larval settlement at the end of 48 h. The results are discussed in the light of its advantages and improving its activity through purification of the crude extract.
