You better go to the Reg 6 office and ask them, Some of your largest steelhead entered the systen as 1 salt fish, Dinks or as some want to call them Jacks, Never spawning, Just checking things out, Then they go back out and might not return for 4 years and these are large fish, So bonking little nates as stating they are poor to the gene pool is foolish thought as is bonking any nate. Fish that enter and spawn and return to the salt might not return to the sytem for 1-3 years after there original spawn and these fish that skip a year will also increase in size the ones that return the following year will be roughly the same size as that all energy goes into reproduction. Alot can be seen in the scale samples as to the age, the years it has returned to the river. And some of the largest fish sampled came back as one or two salt fish there first trip back. So slip the little ones back and let your hog grow.....
