Introducing the brown trout — from basic identification, through to feeding habits, geographic spread, fishing traditions and more. The harder they have to work for a meal the more energy they expend, which, in turn, can negate the energy they receive from the food source they are intercepting. As a result, emergers and flies stuck in the surface film are often taken more readily and more confidently than the full adults that sit firmly on the surface film. Using a soft hackle pattern that simulates one of these drowning insects will be too tempting for the brown to resist. Big Brown Trout are well known for their night feeding and many anglers love going after them. There are no spots on the squarish tail or wormy marks on the back.

Knowing the reason for the change can help you choose a better bait. The fishes’ feeding habits are chiefly dictated by the temperature of the water and by the availability of food. (They can survive in water between about 0° and 20°C provided it is sufficiently well oxygenated, but become increasingly torpid as the temperature approaches either of these extremes.). The trout’s chief objective in life is to acquire enough protein to enable it to thrive and grow, and to do this with the least possible expenditure of effort. Diet of the Brown Trout.
