The rapid growth in sea-cage fish farming in the UK,§particularly in Scotland and Ireland, and the extent§to which intensive aquaculture results in degradation§of the surrounding environment has been the subject§of continued speculation and investigation. Growing§seaweed crops is a possible means of reducing§possible environmental impact through utilisation of§excess nutrients. Cultivation of two seaweed species§with commercial potential: Laminaria saccharina and§Palmaria palmata or Dulse was trialled at three§fish farm sites in north-west Scotland. Yields were§greater close to fish farms and showed that under§optimal conditions, a hectare of P. palmata would§yield up to 180 tonnes and a hectare of L. saccharina§220 tonnes wet weight per annum which would be the§equivalent of at least 13 % and 5 % of the nitrogen§respectively emitted from the production of 500 tonne§of salmon over the two year period the salmon are at§sea. This book reviews seaweed and fin fish culture§and related nutrient dynamics in cool temperate§waters and would be of interest to environmentalists§and those considering fish and or seaweed aquaculture.
