More precise weather forecasting system for fishery sector needed, says IMD DG Mrutyunjay Mohapatra

IMD Director General highlights the impact of rising temperatures on fisheries and the importance of precise weather forecasting.

The India Meteorological Department has emphasised the need to strengthen collaborative scientific efforts to develop a more precise weather forecasting system for the fisheries sector, a key export industry and vital for food security.

“The rising temperatures are taking a toll on both sea fishing and inland fisheries. With rice and wheat production expected to decline under the pressure of global warming, fisheries could serve as a crucial fallback for food security. To safeguard this sector, precise weather forecasting is essential,” said IMD Director General Mrutyunjay Mohapatra while addressing 38th annual day of ICAR-Central Institute of Freshwater Aquaculture, Bhubaneswar, on Tuesday.

Stating that there is rapid expansion of fishery ponds in coastal States marking paradigm shift in aquaculture, Mr. Mohapatra stressed on increased attention on the sector.

“Global temperatures are rising, with an average increase of 1.15 degree Celsius over the past century. In the polar regions, this rise is even more pronounced at 1.53 degree Celsius, while India’s landmass has warmed by 0.67 degree Celsius. As a tropical country, India experiences a stark contrast between maximum and minimum temperatures compared to polar regions. Its atmosphere is convective in nature, leading to an increase in extreme weather events such as cyclones, thunderstorms, hailstorms, and squalls,” he said.

“Fisherfolks are among the most affected by climate change due to their high exposure to these extreme conditions. Just as humans prefer cooler environments, fish thrive in cold water. However, with rising temperatures, the availability of cold water is diminishing. This warming trend directly impacts fish physiology, disrupting their natural regulatory processes,” said IMD DG.

Mr. Mohapatra said, “in search of colder habitats, fish are moving farther from the coast. Traditionally, fisherfolk relied on nearshore fishing, with the IMD providing forecasts up to 75 km offshore. However, as coastal fish populations decline due to rising temperatures, fishers are now venturing into deeper waters. To support them, authorities are identifying potential fishing zones.”
