With the Brahmaputra getting contaminated, the fish stock in the mighty river, has started depleting in Dhubri areas for the past few days.The district is known for different species of fish, but with the abnormal deviations in the colour and quality of its water, the fish stock has started deteriorating worrying fishermen. Fishermen who generally earn their daily bread and butter by selling fish are now in a quandary. They have observed that the water of the Brahmaputra has turned muddy which has in turn affected the fish. Gautam Das, a fisherman and supplier of Brahmaputa fish to various markets, said that during the winter season the Brahmaputra is full of with different species of fish, including ari, borali, chital, rohu and katla. However, these days, the fishermen are able to get a very small quantity while catching fish. He also stated that the chingri fish has suddenly disappeared from the river as none of the fisherman has caught it yet. The water has become polluted and it is unfit for many of the fish varieties and the fish of the Brahmaputra has migrated to the downstream to Bangladesh areas in search of safer water bodies, Das claimed. However, the fish stock and the water quality in other rivers of the district namely Gangadhar, Gadadhar, Champamati, Gaurang and Tipkai have not been affected. Kabil Sk, a fish wholesaler at Dhubri New Market area said, What is more interesting is that this season the fish stock of the rivers has started depleting. The situation is alarming. Although we have very little knowledge about the pollution factor, yet we believe that something is wrong in the water of the mighty Brahmaputra , he observed while sharing information about the depletion of fish stock in the district. Not only fish, but the migratory birds have also disappeared from the banks of the Brahmaputra. According to Sarfaraj Hussain Khan, a local environmentalist, several species of migratory birds are yet to arrive in the Brahmaputra. We have observed that birds have started migrating to nearby beels and rivers instead of the Brahmaputra, Khan claimed without giving any scientific data.
