River Teifi pollution 'killing food sources' for salmon
Coracle fishermen have said they will start returning any salmon they catch because of concerns about fish stocks.
The Teifi Coracle Netsmen have called on other anglers to also catch and release, as concerns mount about fish stocks on the River Teifi.
Natural Resources Wales figures show a decline in numbers, with just over 40 declared net catches on the river in 2015 compared to about 115 in 2014.
Declared rod catches were down from 300 in 2014 to just over 200 in 2015.
An NRW spokesman said the situation was approaching crisis point.
Mark Dellar, a licensed coracleman from Cilgerran, told BBC Wales pollution was one of the reasons numbers were low.
