    The maroon clown Premnas biaculeatus is the sole member in the genus Premnas. P. biaculeatus is commonly known as 'Spine-Cheek Anemone fish' because of the presence of a pair of long spines on its pre-operculum. In India, this species is abundant in the coral reef ecosystem of Andaman and Nicobar Islands situated in Bay of Bengal. Their most striking bright red to maroon colouration on entire body and fin, demarcated abruptly with white to golden yellow narrow bands make them as one of the most attractive species among the marine ornamental clown fishes. Most of the salt water ornamental fishes are collected from the wild and hence there is a serious concern in respect of their conservation. Recent studies also showed that wild collected specimens have a dismal survival history in captivity, whereas captivebred clownfish are generally hardier, more disease free, easily adjust to life in aquaria and retain normal colouration. Due to the very high demand of the species in the aquarium fish trade, development of an appropriate technology for its captive production is felt as an alternative means of providing fish for the trade rather than wild collection which may cause depletion of the stocks. In this juncture, a viable technique has been developed in the marine hatchery of CMFRI, Kochi for the captive breeding and juvenile production of P. biaculeatus for the first time in India.
