Type: article
Abstract: The deepwater seaweed resources survey was carried out during 1986-1991 at the depths \nranging from 5 to 22 m in Tamilnadu coast from Dhanushkodi to Kanyakumari. The \nvegetation of seaweeds and sea grasses occurred in all areas except Dhanushkodi - Mandapam \nand Manapad – Kanyakumari. A total number of 100 algae and 5 seagrasses were recorded. \nAmong the 100 algal species recorded, 20 species belonged to Chlorophyta, 18 species to \nPhaeophyta, 61 species to Rhodophyta and 1 species to Cyanophyta. The total estimated \nstanding crop (wet wt.) from 1863 sq. km. sampled area was 75374.5 tonnes consisting of \n2750 tonnes of Sargassum spp., 962.5 tonnes of Gracilaria spp., 5262.5 tonnes of Hypnea \nspp. and 66399.5 tonnes of other seaweeds. The quantitative analysis of economically \nimportant seaweeds revealed the feasibility of commercial exploitation of Sargassum from \nMandapam to Kilakkarai and Tuticorin areas, Hyphnea from Mandapam to Vembar area and \nGracilaria from Vembar to Nallatanni Tivu region. Hydrological data were, also collected \nfrom the area surveyed.
