Tiny Fry Spotted in Burnaby’s Byrne Creek

Yumi and I saw two distinct size groupings of fry in Byrne Creek on a walk today. There were dozens in the 5 - 7 cm range, and then there were a few smaller ones in the 3 - 4 cm range. I would guess that the larger ones are salmon, likely coho by appearance, and the smaller ones may be cutthroat trout, since the salmon spawn Oct - Dec and the trout spawn Feb - May. Incubation time for trout is 6 - 7 weeks, so that would be about right if they spawned a couple of months ago.

Here's a shot of one of the smaller ones:
