Saviours of fish'n'chips: British scientists find way to breed sea
fish in fresh water



Breakthrough:
Scientists Steve and Frances Marriot have invented a system to breed sea
fish in fresh water
Two British scientists have discovered
a way of enabling sea fish to breed in fresh water. The
breakthrough has major implications for the world's dwindling fish
populations, such as cod, a favourite in fish and chip shops, which has
been harmed by overfishing. Steve Marriot, 57, and wife Frances,
41, made their pioneering discovery while on holiday ten years ago when
they stumbled upon an isolated lake which was used by local tribesmen. The
lake was fresh water but was filled with saltwater fish - and the
couple spent a decade trying to recreate the environment to harness its
unique qualities. The couple, both fish behaviour specialists,
eventually came up with their system, which is a freshwater tank under
controlled conditions. A pool of 300 scientists have contributed
to the development of the system, which takes three months to build and
install. Eighteen months ago the couple's research company Diobas
had just £50 in the bank. They were recently offered £25million
for the business - which they turned down because their breakthrough
has huge potential. The technique has already been licensed for use at a
multi-million-pound blue fin tuna farm in Singapore - which will rear
the fish for the Far Eastern sushi market. The technology will
see sea fish farms set up in fresh water tanks in computer-controlled
environments. It is seen as a massive breakthrough in
international fish production and food supply.



Invention:
Construction work is underway on a 2.8m gallon fish farm in SingaporeMr
Marriot, of Holsworthy, Devon, said their invention could be used
to 'restock the sea' and repopulate stricken species such as cod and
tuna.
He added: 'You could even set this up in the Sahara - the
implications are huge.'
The Marriots are now planning to relocate to Singapore after
claiming they contacted every member of the House of Lords and Commons
to find support - and received none.
An expert on fish behaviour, Mr Marriot has written in clauses to
the licenses of his technology to prevent 'battery farming' conditions.

Experts say that to create a saltwater fish farm on an industrial
scale is extremely difficult and costly.
Salt is a commodity which makes it expensive and trying to control a
sea water environment is technically very difficult.
Previous saltwater fish farm projects around the world - including
off the coast of Scotland - have only enjoyed limited success.

hihi...great project. Hope Happy
