Seems to me with the low returning rate of both hatchery fish and nates. It would only stand to reason that the nets do cause grave damage, But more importantly the streams are only producing a very small amount of fertilization compared to years ago when mass amounts of fish spawned in the rivers, the decaying carcusess are very important for the entire eco-system, Which turns out to be future food for the young steelhead and salmon in the river until they Journey to the Ocean.. We need to start taking all the salmon carcusses form the hatcheries and distribut them to the river system. And then watch and see the return rates start to climb. Stream fertilazation should be major part of any club... Just my thoughts. And I have had my best year on the Nooch this year.. Good Luck and look at it RAIN..
