How to Catch Trout

Hi, i am from scotland and i am fishing in a small width stream, i have been using a rod and fishing with maggots. I have been catching smaal fish but still catn find the big ones. where is a good place to cast and shouldi be using a weight and a hook or stick float with some s/shots ???

Trout are voracious feeders and the bait is best fished deep in pools. I found that when bait fishing, groundbait with the hookbait the evening before the session. It brings trout into the swim.
Keep low to the horizon... though avid eaters, they can be very skittish. look out for undercut banks, rocky outcrops and trees near or in the water too. Worm, bread and cheese are great baits fishing like this as well as with minnows if you can get them too. I believe that the pre bait session in those wild small streams is very important. Do NOT groundbait when you fish it next day. I reckon, if fish came into the pool/swim, you can expect a couple before they skit out.
