Dragon I've got a plan if you can locate a river or stretch of water with sticklebacks - usually slow running streams/rivers or small shallow lakes.
I gave this to our very own sticklebackRcool aka StiX and he was able to catch some sticklebacks with it which then proceeded to breed
Okay so here's what you do ! In true blue peter style

what you'll need is a 2 litre or so coke bottle. Cut it about 1/3 from the top, you need to leave enough so that you can insert that top bit back to front into the bottom 2/3 .

Something like that

Pictures worth a thousand works and my hands are tired

Then simply place in the base the "bait" you're going to use, I have tried many things with great success, a generous amount of fish flakes or if the water is not murky then one of my most sucessful tactics was tin(aluminium) foil ripped up and placed in the base "compartment"

Then all you simply need to do is get some string to hold the bottle in place. I advise setting this out in the morning and checking it at about lunch time. Once I found the thing so full of sticklebacks I swear another one couldn't get in!! so try and put it somewhere you can check it while not disturbing the trap every time you check
Good luck and let me know how you get on
