Brace for potential shifts in community structure of marine resources: CMFRI
Significant changes are occurring in the marine ecosystem owing to the climate crisis, according to Grinson George, Director of ICAR-Central Marine Fisheries Research Institute (CMFRI).
Highlighting the impact of climate change on marine fisheries, he stressed the need for all stakeholders to brace for potential shifts in the community structure of marine resources.
Recently, a transformation is evidently seen in the marine ecosystem. Many fish species, which were once abundant in certain coastal areas, are now scarce, instead new resources are emerging. This offers both opportunities and challenges, George said.
CMFRI is one of the largest marine fisheries research bodies in the world, which is actively involved in regular assessment of marine fish stocks in the Indian Exclusive Economic Zone (EEZ) and studying the impact of climate change in marine fisheries.
CMFRI director pointed out that these changes are a consequence of fluctuations in climate and weather patterns. Physical changes such as rise in sea surface temperature (SST) and ocean currents will have a direct impact on planktons, which form the base of the marine food web. Consequent disruptions in primary productivity have a cascading effect on the marine ecosystem, George said.
He emphasised the need for adaptability and innovation. “While we may lose some traditional fisheries, this also presents opportunities to develop new fisheries targeting the emerging species. However, this requires careful research, monitoring, and a proactive approach to sustainable fishing,” George added.
CMFRI is gearing up to celebrate its 78th Foundation Day from February 1 to 3 with various community engagement events.
