.This study has been undertaken to investigate the composition of submerged aquatic vegetation and their distributional pattern in Chilika lagoon, one of the hot spot of biodiversity, supporting many endemic and endangered species. Submerged aquatic vegetation are highly essential for an estuarine like Chilika like trees to a forest. SAV supports the health of these ecosystems by generating food and habitat for waterfowl, fish, shellfish, and invertebrates; adding oxygen to the water column during photosynthesis; filtering and trapping sediment that otherwise would bury benthic organisms and cloud the water column; inhibiting wave action that erodes shorelines; and absorbing nutrients, such as nitrogen and phosphorus, that otherwise could fuel the growth of unwanted planktonic algae. Therefore they act as good indicator of health of lake ecosystem. The most dominant SAV species is Hydrilla verticillate. For the very purpose their composition and distribution was studied for six months i.e , from oct18 to april 19.
