Crayfish and Cleaning Worms - pretty neat to discover
Posted: Tue Sep 19, 2017 2:07 am
I am a scout leader for the Cub Scouts and we did a pretty short creek walk and using hand held nets and a kick net we managed to catch a very good variety of fish, Crayfish, and smaller invertebrates. In our area we are struggling to control the Rusty Ctayfish so we let everything else go but the Rusty Crayfish which have a short time left.
What was really neat though I have a pair of very modest Swift Stereo Eighty Disecting Microscopes (10x/20x) and I had never looked at crayfish under the disecting scope before. The crayfish had eggs all over their underside and a number of larvae crawling around the crayfish. I really wish I had a camera setup on a disecting scope now!
I just thought I would share as these eggs and worms are not really microscopic but darn to see them with the naked eye is hard but under 10x and especially uner 20x you discover things you never expected!
I need to either buy a trinocular disecting scope or figure out how to add a camera via one of my eyepieces! The Sterio Eighty uses threaded eyepieces so this could be tricky but likely worth the effort!
