Hello.
I will do a lot of experience this spring with light trap.
I have light trap made with 18 liter water tank , another with big A.B.S pipe, for fish larvae.
I have a bucket that floats with transparent funnels to take the Fairy shrimp an Salamander in my Vernal pool.
I received my glow sticks and also aquarium lights of different color.
I almost finished my On-demand feeder, I also made a long rod with ties to put around 20 worms in it , this long rod will be right above the water with the worms, to try to get the perch out to catch them.

But with the Covid everything is more complicated to do.
