    Abstract

    The spawning frequency, lunar periodicity and time of spawning and fecundity in different pairs of orange anemone fish A. sandaracinos from 549 captive spawning were monitored over a period of thirty six months in Andaman and Nicobar Islands during March 2002 to February 2005 for the first time in India. Sex ratios, influence of lunar phase and water temperature on gonadosomatic indices of the species from natural habitat were also documented. Out of the 1333 fishes observed, the female to male ratio of 1:2.2 obtained for the entire period of investigations indicated the predominance of males over females. Due to protandric hermaphroditism, the males were also smaller than female. The highest and lowest values of gonado somatic indices (GSIs) were observed during November and July respectively in both sexes.
