I just looked at the summery for coho on the chehalis .. it shows only 23,801 hatchery return to the chehalis and tribs .. 42,000 unclipped

my ? is how many hatcheries are on the chehalis and its tribs?? how many coho do they plant? out of how many eggs they take? im sure they take millions of eggs from them and only getting 23,000 return?? i dont think the ocean conditions are that bad..

i just dont think they are planting the numbers they say.. or they aren't clipping the numbers they say they are..
