What is the mesh size of that trap. I don't recognize that trap as a common fish or crayfish trap. If you want to buy a good starter fish trap get a Gee Minnow trap. If new,,,, paint it dark colors to match underwater stuff like logs or boulders. I paint mine mostly black, brown and dark green. Small fish are more hesitant to enter a shiny trap. Stay away from the rubber or plastic coated wire trap. They are durable but do not have as high of catch rates. The Gee traps catch about all types of small fish except LMbass who avoid entering about all types of traps. The trap funnel opening can be enlarged or reshaped to catch larger fish. Build a big version of the Gee trap or a box shape trap for catching and sampling large fish; again catching about all fishes but LMB.
