| 1 | Seagrasses and algae of mangrove swamps The physiography of the Indian Ocean Basin is given and the distribution of marine vegetation in six distinct coastal areas are compared. The mangrove area, length of mangrove coastline and total coastline have been shown seagrass community as a coastal resource and its impact in the ecosystem has been discussed. Based on the type of substratum with which the primary producers (algae) are associated, are called as epipelagic, episammic, epilithic, epiphytic and epizoic. Biomass and productivity of seagrasses are mostly based on two genera, Zostera and Thalassia. Quality of light and water temperature, besides chemical, biological and other factors account for the seasonality of occurrance of algae. The epiphytes play an important role in the food web in seagrass system. The vegetative and seed-seedling methods are the two transplantation methods adopted for the restoration of seagrasses. Seagrass beds exercise their influence on their surroundings. National sea programme is to be enunciated to understand maintain and improve the coastal ecosystem for the restoration of mangroves, seagrasses and seaweeds Source: Lakshmanan, K.K.
