The brown trout is indigenous to Europe, North West Asia, and North Africa. It shows a remarkable diversity of shape and coloration, often according to locality. It can be categorized into two distinct forms which differ chiefly in life style but also in size and colour. The Sea trout is the migratory form.
The brown trout is the nonmigratory form which lives in rivers and lakes. The steeper gradients of the rivers where brown trout survive best are often a long way from the sea, and in many rivers they are separated from the sea by the slower sluggish zones which trout tend to avoid. Often mild pollution also bars the way to the sea. In any event the brown trout has been separated from the sea for many generations and has adopted an entirely freshwater mode of life.
Although trout can be taken on many baits, including the lowly maggot, worm, spinners and lures, the artificial fly is the offering most used to attract this game fish.
Wet and dry flies
Trout are taken on wet and dry flies. The basic difference between these is that the hackles on the dry fly stand out, making it float, while the wet fly’s ‘wings’ run back along the body.
Boats have both advantages and disadvantages for the trout angler. Although a boat gives access to the whole of a large water, unless you are anchored or in a flat calm, it also makes it difficult to fish a fly below 23ft.
Methods and or flies are restricted on some waters, although the rules may be eased as the season progresses. But do not worry if the rule is nymphonly. Records show that more heavier fish are caught on imitation flies than on lures in these waters. The reason is probably that the newly stocked fish either get wise to lures quickly or get caught.
Most small fisheries are shallow, so there is no need to plumb vast depths for big fish. Typical tackle for nymphing is an 8^ft glassfibre rod with matching floating line and an 8ft leader of 8 lb b.s. Line, with perhaps one dropper. Popular flies are black, brown and green midge pupae, orange and brown sedge pupae, leaded and unleaded Pheasant Tail nymphs, Shrimp, Corixa and Black and Peacock spider.
