Abstract :
The stored carbon in the thallus of three seaweed species (Enteromorpha intestinalis, Ulva lactuca and Catenella repens) was estimated in three different seasons (pre-monsoon, monsoon and post-monsoon) from four sampling localities in the deltaic ecosystem of Indian Sundarbans (21040/ N to 22040/N and 88003/E to 89007/E). The average stored carbon content varied from 1022.18 g m^-2 (during monsoon) to 1067.02 g m-2 (during pre-monsoon) in Enteromorpha intestinalis. In Ulva lactuca, the stored carbon ranged from 46.41 g m^-2 (during post-monsoon) to 152.43 g m^-2 (during pre-monsoon). In case of Catenella repens, the range of stored carbon is 13.70 g m^-2 (during monsoon) to 51.44 g m^-2 (during premonsoon). Amongst the seaweed species undertaken in the study, E. intestinalis showed uniformity in biomass between sectors (pcal = 1.62 pcrit = 18.51) and seasons (pcal = 2.43 pcrit = 4.14), which implies tolerance of the species to variable salinity . Highest values of stored carbon were recorded in E. intestinalis, which might indicate its role as potential candidate species in the blue carbon series of Indian Sundarbans deltaic complex.
