Warmer waters at Welsh sea bass farm

New technology has been introduced to the Bluewater Flatfish Farm, located on the island Anglesey off the Welsh coast, to increase the numbers of fish, BBC News reports. It works by using the heat generated by the fish swimming to raise the temperature of the water.

Managing director Phil Gatland told the news source that two processes were used to heat the tanks housing the fish. One was the recycling of water from the tanks - where it was cleaned and any heat retained - and the other a biological process which converted ammonia produced by the fish into heat.

Initially it will take several weeks to rise, but the water temperature will eventually be a constant 20-22C in the tanks, he said.

It is hoped around 1,000 tonnes of sea bass will be produced each year, with the first batch available in October, BBC News wrote.

Bluewater Flatfish Farm is owned by Greek company Selonda and was established on Anglesey in 2002. The sea bass fishery is an extension to a turbot fishery already on the same site.
