Potential of Ulva linza L. and Caulerpa racemosa var. uvifera seaweeds from Cox’s Bazar, Bangladesh as sea vegetable

The nutritional quality parameters of leafy Ulva linza L. collected from the west coast of the Naf river estuary, Teknaf and grape-like Caulerpa racemosa var. uvifera collected from St. Martin's Island, Cox's Bazar, Bangladesh, were studied. Total protein content in U. linza (22.05±1.73%) was found significantly (p<0.05) higher than C. racemosa var. uvifera (18.20±1.50%) but with low crude lipids in the former; total amino acid content was also higher in the former, both having nearly the same amount of essential and non-essential amino acids; vitamin C content (about 2.5 mg/100 g) was nearly identical but β -carotene content was higher in the later (9.04 mg/100 g dry wt.). Crude fiber in U. linza was low (4.21±0.43%) but high in C. racemosa var. uvifera (18.20±1.50%). Other micronutrients were also ascertained. The nutritional quality parameters determined suggested that the “sea-salad” and “sea- grapes” can be used as sea-vegetables and food supplements. Bangladesh J. Sci. Ind. Res.56(3), 223-230, 2021

New records of seaweeds from southeastern coasts of Cox’s Bazar district, Bangladesh

Gracilaria tenuistipitata var. liui Zhang et Xia 1988 from sand-flat at Nuniachara, Cox’s Bazar, Ulva linza Lin. from west coast of Naf R. at Noapara, Teknaf and Fishary Ghat in River Bakkhali, at Cox’s Bazar, and Caulerpa fergusonii Murray from St. Martin’s Island (SMI), have been newly recorded and illustrated from Bangladesh. C. chemnitzschi (Esper) Weber-van Bosse var. irregulare Aziz & Alfasane var. nov. and C. sertularioides (S.G. Gmelin) M. Howe var. robusta Aziz & Alfasane var. nov. from SMI, Cox’s Bazar District, Bangladesh are new to science. Total number of marine algal taxa so far recorded from Bangladesh coasts is now 210.
