if this virus could possibly kill other species I would say no..but I think they have tested it fully..i have never seen redfin in any waterway where I have fished so I cant comment on them..one river I fish has carp to the headwaters and is dirty thru the whole system.another I fish has carp up to natural falls and none above so far..clear water all the time..i have seen the natives thriving in both so the cod and goldens in my clear river obviously don't need carp to survive..the amount of small fish I seen on the wknd was amazing..also tiny cod that make the population look so healthy its not funny..the only thing missing in my spot is large fish which I think are being taken by bait fishos during holiday periods..the carp in the downstream section are huge and in large numbers I would love to see them gone or thinned out at least .in my opinion the river would come back to its previous years of quality when I first fished it 35 yrs ago before carp were a problem and the water was clear ......next
