Coastal Resource Assessment and Management

Critical Habitats

Establishment of NCCR Field Research Centre at Gulf of Mannar

Coral Reef Monitoring -Health Status

NCCR started extensive underwater surveys to investigate the present health status of Coral reefs in Gulf of Mannar. Reef monitoring has been completed in the Mandapam group Islands, and further surveys are ongoing in other Islands of Gulf of Mannar to compare the reef health status from the year of 2000.

 

 
 

Coral Reef Restoration

Restoration of coral reef activities were initiated to increase the live coral cover in and around Islands of Gulf of Mannar and also to study the impact of sedimentation and epiphytic flora & fauna on live corals.

 

Capacity Building

Underwater training programs were conducted on coral reef monitoring & restoration activities for the officials of Wild Life Division (Gulf of Mannar Marine National Park Authority) for effective management and conservation of coral reef habitats in Gulf of Mannar Islands.

 

1.Monitoring of Coral Reef Health Status

NCCR has undertaken extensive underwater surveys to investigate the current health status of Coral reefs in Gulf of Mannar. These investigations are to find out the important marine resources in Gulf of Mannar and also to trace out the possible threats to Coral reefs and reef associated biota.

  • Surveys were completed on reef health monitoring in Mandapam group of Islands.
  • Recent studies revealed maximum percentage of live coral cover in Hare Island, Krusadai Island and Shingle Island. New recruitment of reef building corals (Acropora sp., Echinopora sp., Porites sp.) are recorded from Hare Island, Manoliputti Island, Krusadai Island and Shingle Island.
  • Poomicharan and Pullivasal Island have the maximum dead coral cover recorded from Mandapam group of Islands.
  • Sedimentation, Coral disease, destructive fishing activities, Invasive algal species (Turbinaria sp., Sargassum sp., Lyngbya sp., Caulerpa sp.) are major threats to the coral reefs in GoM.
  • Reef health monitoring surveys are still in progress for other group of Islands in GoM.

 

2.Coral Reef Restoration

Coral reef restoration activities are initiated to increase live coral cover in degraded areas and to study the impact of sediment deposition on growth and survival rate of corals.

  • Suitable sites have been identified and initiated the coral restoration activities in Hare and Manoli & Manoliputti Island.
  • Regular monitoring and observations are underway.
  • Preliminary observations revealed the development of coral fragments by depositing calcium carbonate on cement slabs.
  • Data collection on growth and survival rate of coral fragments are under progress.

 

3.Capacity Building & Training Programme

Various training programmes on Coral Reef Monitoring and Coral Restoration activities were conducted for the officials of Gulf of Mannar Marine National Park authorities, researchers, and local fishermen communities.
