At the moment, the bylaws state that each day an angler is permitted to take from rivers:

1 pike (up to 65cm)
2 grayling (30cm to 38cm)
15 small fish (up to 20cm) including barbel, chub, common bream, common carp, crucian carp, dace, perch, rudd, silver bream, roach, smelt and tench

Many anglers have witnessed a depletion in numbers of fish stocks in their local venues.
This is unsustainable if we continue to permit anglers to take this number of fish per person, per day!
