Regarding the tackle for catching roach, keep it as light as you can get away with. Although roach don’t grow huge, they really do put up a great fight for their size. For this reason keep the tackle light so you can fully appreciate this stunning fish. I like catching roach mainly on my local river. My preferred method is using a stick float and trotting it down stream. I find this presents the bait in the most natural way possible. Roach can be quite wary at times. If it don’t look like it’s falling through the water naturally it might just put them off and leave your swim.
For this type of fishing I use a light float rod a 3000 size fixed spool reel, 4lb mainline and a 2lb hook length with a size 18 micro barb hook. Always have your mainline slightly heavier than your hook length. There is a good reason behind this. If you happen to get snagged up or snapped up by the fish, the line will snap down near the hook. The last thing you want is metres of line being left in the fishes mouth or left in the water.
A lot of roach anglers will use a centre pin reel whilst trotting on a river, which is ideal due to the way the line gets released of the reel smoothly. But if you are a beginner to fishing I would suggest a fixed spool reel, you will be less likely to get in a tangle.
If you are planning on fishing large venues such as gravel pits for roach you may want to get yourself a feeder rod. These have a bit more backbone than a float (match) rod and are designed for casting swim feeders. Due to the extra weight of the swim feeder you can get more distance when casting. Sometimes on the bigger venues you want to get to places a float rod just wont reach.
