Low fish catch – India

Maharashtra witnessed lowest fish catch in 45 years in 2019. Fishers have also reported a 50% decline in their annual fish catch, attributing recurring cyclones for reducing their fishing window. Fish migrate from warm waters to cool waters, a phenomenon that has already begun as the Indian ocean is warming up is one of the reasons for lower fish catch. The marine algae that is the base of aquatic food web has been disappearing in the western Indian Ocean owing to rising sea temperatures.
