Cumbarjua Fishermen's Ekvott and Cumbarjua Nadi Bachao Samiti have threatened to agitate if the government continues with its ostrich-like attitude to the death of fish in the river. Addressing a press conference here, Samiti President and Panch member Nityanand Sawant and secretary Mahendra Gaonkar said fishing activity has come to a halt as fish is dying due to release of discharge by a sea food factory located nearby.
