 Usually, in summer months, a spinner or fly manoeuvred across the surface will bring about a take from a fish, due to the tendency of fish to move into the warmest part of the water, the surface and first layer (about 18 inches) of water below.When fishing a river for coarse fish species such as chub, barbel, roach, dace and bream, the favourite hook baits tend to be maggot (white, red, and bronze), caster (maggot chrysalis), worm, cheese, pellets (halibut, trout, and carp), boilies (round boiled baits typically made with fish meal, milk, and soya) and luncheon meat.Loose feed can be any of the above baits with a particle bait fed by hand, in a feeder, or by catapult, sometimes in the form of hemp seed, a manufactures fishmeal ground bait.
