Chum in a creek don't make hatcheries money, chum in the hatchery make hatcheries money.

If I have to, I will get a non profit business ID or find one that will help and raise the money to raise them. 4 years later they should support themselves and hopefully another 500K to 2M more sought after species.

Estimated feed costs to raise 500K Chum: $1,000 $0.002 cents a fish; possibly even less, and they can be released without feeding them with decent returns, so they could cost ZERO in feed and minimal added operating costs.
Feed Cost to raise 500K Chinook $7K, 2010 actual costs $0.014 a fish 7x more
Feed Cost to Raise 970K Coho $62K 2010 actual costs $0.064 a fish 32x more
Feed Cost to Raise 155K steelhead $27K 2010 actual costs $0.174 a fish 87x more

BTW, Humptulips hatchery production capacity: over 6M
Current usage: about 20% or 1.2M

And let this be clear, I do not want any reductions in anything else because of raising Chum, Getting Coho back to 970K, keeping Chinook at current levels and increasing Steelhead are all things I would like to see. Maybe even increasing the numbers of all IF it is determined that impacts will be negligible on native stocks.

Operating costs stay pretty much the same except for clipping costs and slight increases in water needs. Chum are NOT clipped so they do not add to clipping costs. A negative aspect but not much that can be done about it since they are released so small.

Cost is IRRELEVANT in this plan. I will find a way to raise the money so it doesn't cut into other fish production. The return is what is important here. High value carcasses to raise money to raise more highly valued table fair fish.

This is what I have heard that really matters IMHO:
Wild impacts
Increased netting
Commercials netting bay
Not marked
Won't be a draw for people to fish Grays Harbor
If I missed something or there is something that hasn't be said I want to hear it.

As for them being a nuisance or that I simply don't eat them: Release them if you don't eat them. If you can't catch Coho and/or Chinook without hooking chum all the time don't fish while they are in. Or ask those of us that know how.
