REVIEW AND SYNTHESIS OF THE ENVIRONMENTAL IMPACTS OF AQUACULTURE
CHAPTER ONE INTRODUCTION
1.1 This report considers 5 main areas relating to the interaction of aquaculture with the environment:
- The discharge of waste nutrients and their interaction in the wider marine environment
- Effects of other discharges from aquaculture, e.g. medicines and chemicals
- Disease impacts on wild and farmed stocks
- Escapes from fish farms and potential effects on wild populations
- Sustainability of feed supplies - including research on plant meal substitution.
1.2 Each section is structured to contain a description of the most important features of each area including, where appropriate, reference to the assimilative or environmental capacity with respect to that topic, a short summary (which has been used as the basis of the Executive Summary) and a description of the main areas where further research is required.
1.3 In order to determine the current level of research activity in the area of environmental interactions of aquaculture, a questionnaire was circulated widely at the international level. The summarised outcomes of this questionnaire are presented as an annex to this report in tabular form.
1.4 References to the published literature have been deleted in the interests of providing a brief and easy to read report. A full reference list is available on the Web at http://www.scotland.gov.uk/cru.
