I looked on Washington Department of Fish and Wildlife, you can get eggs that are fertilized and treated with iodine. There are a few schools in the area that do this, they don't help with equiment though. The elementry school i went to did this. Get the eggs in the fall raise them in a tank untill spring when they are almost ready to head down stream. This first stage of life is when a lot die and get eaten so this helps thier numbers. On the application you can ask for 100, 200, or 500 eggs, the schools usually do 200 eggs in a 55gal so i figure if i can get the 125 set up then i could do the 500.
The chiller is the part screwing me, since this would be a seasonal tank i don't want to spend a bunch of money for this. I already have the tank and filtration and what not, so the chilling, and maybe heating if in the garage is the only real obsitcal in my way.
I might just have to settle for the 75 but even that might be hard to maintain at 50
