There are of course a huge number and variety of fish species in fresh and saltwater habitats across the world but they have, with certain exceptions, the above characteristics in common. The most important point to remember is that they all have the capacity to suffer pain and stress. Angling is the catching of fish by the lips with rod, line and hook and can also be called fishing. It is undertaken primarily for the enjoyment of the angler, who gets pleasure from outwitting a fish into being caught. Most are considered inedible so are usually thrown back.
All coarse anglers have to buy a rod licence and they can then fish wherever it is permitted.
There is still a close season on rivers and most canals from 15th March to 15th June. This is practised from beaches, rocks, piers and boats. All types of fish are caught, from flatfish to huge sharks. Sea fish are seldom returned alive to the water as most are considered edible. No rod licence is required and there is no close season for sea angling.
