Opis

The rapid growth in sea-cage fish farming in the UK,particularly in Scotland and Ireland, and the extentto which intensive aquaculture results in degradationof the surrounding environment has been the subjectof continued speculation and investigation. Growingseaweed crops is a possible means of reducingpossible environmental impact through utilisation ofexcess nutrients. Cultivation of two seaweed specieswith commercial potential: Laminaria saccharina andPalmaria palmata or Dulse was trialled at threefish farm sites in north-west Scotland. Yields weregreater close to fish farms and showed that underoptimal conditions, a hectare of P. palmata wouldyield up to 180 tonnes and a hectare of L. saccharina220 tonnes wet weight per annum which would be theequivalent of at least 13 % and 5 % of the nitrogenrespectively emitted from the production of 500 tonneof salmon over the two year period the salmon are atsea. This book reviews seaweed and fin fish cultureand related nutrient dynamics in cool temperatewaters and would be of interest to environmentalistsand those considering fish and or seaweed aquaculture.
