The humble roach is one of our smallest freshwater species but it's one of our most sought after, especially when they reach specimen proportions. They are a sleek fish having silvery blue flanks, large orange-rimmed eyes, white/cream underbelly and red fins. The lips of this fish are level, unlike the very similar size, shape and coloured rudd, whose lower lip protrudes. Roach tend to undertake a slight colouration throughout the year. In summer their flanks become quite brassy, while in winter the scales upon the flanks take on a really attractive blue tinge. The dorsal and forked tail fin are darkly coloured and tinged with crimson. In normal conditions the average size of roach caught on rod and line will be around the 4-8oz mark. In lush and food-packed venues it will quickly pile on weight and can quickly ascertain a specimen size of 2lb and over.
