Salmon egg supositions...
Posted by AlaskanAuthor on Apr 27 2005
Claymore offers a great site for the "how to" of what you are doing.
Deductively, here's my researched and educated guesses to your questions and comments:
1. I would go with the solid egg color, and the reason why is really quite simple. Freshly deposited salmon eggs take about 4 months until the alevins (developmental hatchlings) emerge as fry (baby fish). You are correct in that they they will undergo color change as they later incubate, but if you think in terms of timing during that incubation, fishermen are long gone due to the ice-up of the stream.(eggs deposited in September emerge as fry in January)
So, if you are really the purist and are after the match, I would advise that you fabricate in the opaque hues that are dropped during the time you are on the stream.
2. As far as salmon eggs staying round after deposit to the redd(nest), the ones I've seen remain round. (and most of those come from the bellies of the trouts or chars I've opened to see what they've been up to) Even bounced out eggs still stay pretty much round in shape; salmon egg skins are pretty tough; that's why salmon roe caviar explodes in your mouth if you happen to consume them.
3. As far as color change goes, those eggs I've observed that have washed out of the nest, lost adequate stream ciculation, or have been subjected to warm water, turn from orange to light pink and then on to almost white. (little wonder the fly guys nail the stream side opportunist fish so well; they'll switch out egg pattern colors in a heartbeat until they find the match that works best in their particular stretch of the water)
Have fun with your clay eggs. The oil added to the clay body will assure adhesion to your hook and will resist water. Me? I'd rather eat the caviar then try to fish with what looks like it...
