Actions have to be taken to preserve the endangered species of fish. Those which can be reared in the artificial conditions might possibly be produced in large scale at the lab and transferred to the the natural habitats. Necessary research need to be done to produce those endangered species, if methods are already not available, under captive condition. Simultaneously measures are to be taken to assure the cleanliness of natural waters in the rivers. T.M.Sankaran Gold Member, SPK

The revers are getting polluted day by day and the waste materials and chemicals are dumped into the water resources without any social concerns...The Industries and Municipal dumping yards are established near to the river beds...Backwaters full of Aquatic weeds & plants...Drainage systems opening to the revers...And above all,,during summer we wonder that here there was a river!!! This is our own god's own country...This is a major threat to the great biodiversity of our land...Not only for aquatic organism but also for human beings...
