An efficient mass propagation method for Feronia limonia was developed from excised shoot tips and nodal explants of in vitro grown seedlings. Explants were cultured on MS medium with different conc. of NAA, Kn, IAA and BAP singly or in combinations. Highest number of micro shoots and better plant growth were obtained from these two explants on MS medium supplemented with 0.2 mg/l BAP alone. The regenerated shoots were successfully rooted on MS medium supplemented with 0.5 mg/l NAA. The in vitro raised plantlets were successfully established in soil following the formation of roots with 100% survivability under ex vitro condition.

Five species of marine a1gae were collected from Saint Martin’s island, identified and biochemical analyses were carried out in BCSIR Laboratories, Chittagong. Biochemical composition were analysed to evaluate its food value and also to find out variation in composition during the period of investigation. The protein content of Sargassum coriifolium was 16.07%, whereas in Padina ltenuis that was estimated at 8.32%. The percentage of fat in Sargassuni coriitolium along with the other sea weeds was 0.5%. It was found that major of the biochemical parameters of these sea weeds were higher except the protein contents than that of Spirulina . The carbohydrate content in Dictyota dichotoma (38.94%) was lower among these sea weeds, but more than that of Spirulina . Carbohydrate contents were higher (56.29%) in Hypnea musciformis . Mineral contents as well as other parameters, especially carbohydrate contents were higher in these algae than that of Spirulina .
