Salish sucker population estimate at Chawathil.
We tattoo as many as we can catch, then come back a couple of weeks later to trap again. We use the proportion of the fish in the second catch that are marked to estimate the total population. We also found loads of amphibians in some areas:)
Thanks to Nick Henry for top notch field assistance!
Predaceous Diving Beetle, Chawathil
pearsonecological.com/inverts-l3/predaceous-diving-beetles/
We often find these in fish traps set in weedy ponds and sloughs.
They are big, up to 50 mm long (2 inches), and fast swimmers.
Wow, gorgeous picture!!
These guys are so cool!!
Nice photo!
Do you normally find them in waters where predatory fish like salmonids are absent? On interior lakes, the presence of these insects usually means that there are no trout due to winter kill or other factors.
