Examine the role of CMLRE in marine biodiversity research and fishery resource assessment within India's EEZ.

The Centre for Marine Living Resources and Ecology (CMLRE), Kochi, functioning under the Ministry of Earth Sciences, is India's nodal institute for surveying, assessing and monitoring living resources of the Exclusive Economic Zone and adjacent seas [1]. Its work underpins both marine conservation and the Blue Economy push.

Marine biodiversity research

• Repository role: its "Bhavasagara" Referral Centre was designated India's National Repository for Deep-Sea Fauna by MoEFCC under the Biological Diversity Act, 2002, holding over 3,500 geo-referenced voucher specimens, more than 70% of them deep-water and open-ocean species [2].
• Data systems: CMLRE convened a national workshop on IndOBIS (Indian Ocean Biogeographic Information System) to standardise biodiversity documentation [3].
• Ecosystem monitoring: its post-wreck cruise on FORV Sagar Sampada after the ELSA 3 sinking sampled 23 stations between Kochi and Kanyakumari, detecting petroleum-derived pollutants in zooplankton and damage to fish eggs and larvae during the monsoon spawning season [4]; a rapid ocean study followed the hazardous cargo spill south off Kochi [5].

Fishery resource assessment

• The Marine Living Resources Programme, executed through FORV Sagar Sampada, generates stock and oceanographic data for ecosystem-based management of the EEZ [1].
• Such assessments underpin national policy: NITI Aayog's report on India's Blue Economy: Strategy for Harnessing Deep-Sea and Offshore Fisheries places the EEZ's potential yield at 7.16 million tonnes, largely untapped beyond the shelf, and recommends a Deep-Sea Fisheries Authority and stronger scientific manpower [6].

Constraints

• Dependence on a single dedicated research vessel limits survey frequency; Parliament has sought clarity on the adequacy of marine living resource monitoring [7].
• Assessment outputs still translate slowly into fleet modernisation and enforcement.

CMLRE thus supplies the scientific backbone linking biodiversity conservation with responsible resource use. Strengthening its survey fleet, integrating IndOBIS data with fisheries governance, and institutionalising a deep-sea authority would convert this knowledge into sustainable harvest — advancing SDG-14 and India's Blue Economy vision.
