a look at some landlocked Chinook roe...

My bro Matt caught a 22 inch Chinook from Lake Almanor that was just starting to turn color.  Inside the fish, we found some very interesting roe.  It was a mixture of mature and immature eggs.  I wonder if this is a normal thing for landlocked Chinook in this lake?  Normally when I catch a mature salmon from here I'll just let them go, but this fish was still bright enough to be kept and make for quality tablefare.

I don't have any answers as to whether the mature-looking eggs were actually viable, but thought the photo would pique some curiosity around here.  Any fish-heads have more intel on this?  Adam, Naoaki?  Also, what the hell is a Chinook doing in spawning condition in March?  Are there winter-run genes in there somewhere? 

Yeah, I'd like to hear the explanation also as I've seen that in Amador trout.

Fukushima!

Something natural stick clicks in the fish to spawn. Just like the koke's will turn and attempt to hit the creeks and rivers feeding the lakes to try and spawn.
