Ewan Clarkson described Gudgeon as always looking so cross when you catch them, like retired colonels called from the bath to answer the telephone ... gotta love them for that, and for saving so many blanks, and for that flash of lilac when they were pretending to be brown and boring.
Roach - what can you say? The be-all and end-all for many; deliberate roach fishing is about as subtle and refined as it gets. Bread punch on winter canals, wheat on summer rivers; hemp and tares, hemp and caster, hemp alone, or big lobworms and lumps of flake; stck-float, dart, or great big swan-quill Avons as circumstances dictate - got to love the Roach for the sheer variety of tactics he calls for, and for being a bar of silver with scarlet underfins.
Variety of methods - oi, what about Chub? Add spinning, freelining, and fly fishing to the list, at least! So shy, so greedy - a chub is nearly always possible, and, if caught, always deserved.
I could also go on about tench, barbel, rudd, (mmmm... rudd!), perch (so long as they don't swallow the bait beyond disgorger-reach), bream (once they're brown).... and all the others. Wonderful. As in "Full of Wonders".
It does have to be admitted that small perch, ruffe, bleak, and small eels have a definite pain-in-the-neck value when caught by fair angling, but watch 'em, in the wild or in an aquarium ... amazing, the lot of 'em.
