[00:00.49]Fish and chips has always been a favourite dish in Britain,
[00:05.18]but as the oceans have been overfished, fish has become more and more expensive.
[00:10.98]So it comes as a surprise to learn that giant fish are terrifying the divers on North Sea oil rigs.
[00:19.02]Oil rigs have to be repaired frequently and divers, who often have to work in darkness a hundred feet under water,
[00:29.08]have been frightened out of their wits by giant fish bumping into them as they work.
[00:35.85]Now they have had special cages made to protect them from these monsters.
[00:41.30]The fish are not sharks or killer whales,
[00:45.15]but favourite eating varieties like cod and skate which grow to unnatural sizes, sometimes as much as twelve feet in length.
[01:00.31]Three factors have caused these fish to grow so large:
[01:04.35]the warm water round the hot oil pipes under the sea;
[01:09.15]the plentiful supply of food thrown overboard by the crews on the rigs;
[01:14.67]the total absence of fishing boats around the oil rigs.
[01:18.83]As a result, the fish just eat and eat and grow and grow in the lovely warm water. Who eats who?
