Our Cohos have some strange visitors
Our Coho smolts had a couple of strange visitors the other day: pumpkinseeds.
Pumpkinseed is an introduced species and rumour has it that it was introduced by the Fraser Valley Trout Hatchery about 100 years ago. This is what a document in the DFO library has to say about pumpkinseeds:
Pumpkinseed prefers the same habitat as juvenile Coho Salmon (Oncorhynchus kisutch) though it has not been found to have a direct effect on Coho. It was not found to consume them directly, and the growth rates of Coho juveniles in areas with Pumpkinseed were greater than growth rates in neighbouring areas without Pumpkinseed. – (provided by Dave Clough)
Apparently, pumpkinseed help keep the water clean and perhaps the Coho smolts benefit from this. An interesting relationship.
Since May 10, we have counted 513 Coho, 113 Steelhead and 15 Cutthroat trout. By May 10 last year we had counted 4,313 Coho, 61 Steelhead and 8 Cutthroat trout. It’s a very different year so far with interesting surprises. Don’t miss out. See you at the smolt trap.
