So my local club has issued a ban on returning catfish caught on our canal. If you catch one it needs to retained, it will be removed and released into a local pond. Originally the idea was to have it killed, but I think a lot of the anglers kicked up a fuss about it hence now they moving them to a pond.
My question is, how bad are these fish for our waters? We have otters killing fish all the time, cormorants putting holes in to fish. Boats and pollution releasing chemicals etc into the water.
From my understanding the ea won't put anymore stock into the water until the catfish are removed.
Are catfish really that bad to our waters?
