"For hundreds of years Chinese fishermen have been using hand-reared cormorants to hunt for their supper.

The birds, which are considered a pest by some anglers in Britain, swim deep underwater searching for a meal.

They are fitted with a ring around their neck before they dive to prevent them from swallowing their catch.

This means that when they do resurface, they will regurgitate the f More..ish before returning to hunt again.

When the fisherman's bags are full, the ring is removed and the cormorant rewarded with a meal.

Some anglers handle more than ten birds at a time using various calls and the tradition has a large following in Xitang Town, Zhejiang Province, south-east China.

The dark, sleek cormorants are easily recognisable as they tend to stand with their wings outstretched after diving, possibly to dry themselves"
