I found this online and think you should take a read. Sea trout are still under huge pressure due to the filthy business of salmon farming and these wonderful sporting fish are now extremely rare in most west coast rivers.
I fish the Bunowen sometimes, a classic spate river which should provide good sport after a spell of rain. I didn’t bother fishing it last season though as stocks of both salmon and sea trout were at an all time low. Locals who know every stone on the bottom of the river saw few fish and despite some perfect spates the fish simply did not appear. Until the fish farms are removed our sea trout will continue to suffer from sea lice attack. Eaten alive at sea they die before reaching the river. Those that do make it back to fresh water are lean and scarred, dreadfully weakened and susceptible to disease. The Irish government don’t want to hear about this, big business is never challenged in this country.
I don’t know if I will bother fishing the Bunowen this coming season. I suspect there will be no sea trout again this year and it is depressing swinging flies through the runs and pools when they are devoid of life. only when the accursed cages with their filth and poison and lice are consigned to history will the silvery trout come back. We are a long, long way from that happy day……………….
