Yesterday I went to a local store and bought 2 fish (IDE, leuciscus idus). I found eggs in both of them but they were completely different (look picture below).
Why there is such difference? I have only one explanation - the light eggs are ready for spawn but the dark eggs aren't ready yet. The color of fish were a bit different and that makes me think that they were caught in different places and that could explain my theory.
Any other ideas?
