if y'all like CCC, try the #CanalCamLeiden, in an urban canal in a #fishreservation in the Netherlands! Usually clearer than the famous Utrecht Fishdoorbell #visdeurbel . With individually recognizable tench, bream, rudd, pike etc. Enjoy!

Has anyone seen this before: rudd/ Scardinius erythrophthalmus with a throat-tumor? Or maybe an infected swallowed hook?

We're hoping to snap some beautiful images, too, next year. Here's the purchase list of our CanalCam contraption. To be assembled this winter 😉

does the shark have a hook with fishing line embedded in its mouth, I wonder?

Today a test of battery, wifi and display. A few time a blue screen, so we need to do some more work on the wiring
