The contents of yesterdays steel. Strangly enough neither of the fish caught today had anything in them, but they were in a different section of the river. There were 4 eggs in one fish and about 100 free-living caddis (Hydropsyche) in one stomach, and about 200 Hydropsyche in the other.
notice how perfectly preserved they are.....in a normal fish stomach those things would last only a matter of hours before they would be mush...they will eat but they wont get any nourishment because the digestive system is shut down. Thanks for the very cool pics zen.
Right you are Tom, proves the fish can't metabolize but still feed. Does a steelheads digestive system turn back on after they are finished spawning? I have heard great lakes fish go on a feeding binge and they are swiming back out to the lakes when they are fished spawning...wonder if that applies to the west coast
well in most systems, the majority of the fish die after spawning. There is however a variable percentage of repeat spawners. They tend to be mostly females. These fish will chrome up very quickly after spawning, and begin feeding voraciously soon after. Most of this feeding will take place in the salt though where food is available in much greater quantities.
Corey, all eggs were single and larger than the eggs one would find in a spawn sack. And, i don't think many people fish single eggs for steelies. They were also all intact fully, but i broke some of them on removal. I think the eggs were from hens that were more mature than those i caught dropping eggs, although it could be someone fishing.

Yeah outmigration numbers are under 1% for snake and columbia fish. Pretty whack. Maybe someday we can get some wind power and Take those antiquated things down.
