I made an improvement on my small fish trap. Before, I used to use only one water bottle to make the trap and didn't staple it shut, but it was difficult to keep the two pieces in the place that I wanted them. This time I used 2 water bottles and my stapler. I love how easy this is to use now!
Items needed to build trap;
two small water bottles
fishing line
binder clip
stapler
sharp knife or scissors
Instructions;
take label off of plastic bottles
cut one bottle at the base of the curve (near the water line when the bottle was full). then remove the cap
cut the other bottles' bottom off
take the bottle top that now resembles a funnel and insert it into the bottom of the other bottle with the mouth on the inside of the trap
staple around the edges to hold these two pieces together
tie fishing line to one of the staples (easiest to staple the line to the bottles and then tie it)
tie other end of fishing line to a binder clip that is large enough to clip on the top of the aquarium
drop some delicious bait into the trap and slowly lower it to the floor of the aquarium (resting on it's side)
clip the binder clip to the top of aquarium (or edge of glass lid)
to empty trap, pull on the fishing line and remove the trap. Unscrew the lid to put your catch where you want it to go.
Alterations that can be made;
use liter or 2 liter bottles for larger fish
instead of removing the cap on the "funnel" end, just drill or burn a hole in it to catch only fry
Tips;
I use Repashy, Blood Worms, Frozen Brine Shrimp or earth worms to bate the trap. Must be delicious!
I set the trap before I go to bed, turn off the light and check it first thing in the morning.
I use this method to trap my shrimp for sorting by colors
