We will monitor the extent to which Atlantic salmon use a low salinity surface layer created inside a new sea-cage design - the Well cage. This cage design is aimed at combined control of salmon lice and amoebic gill disease. Salinity tags will be used to monitor salinity histories of salmon at four 60 days time intervals during a production cycle to account for fish size and seasonal differences.
Tagged fish are expected to experience minimal distress during surgical external attachment of tags, for which they will be anaesthetised. The tagging method to be used is widely adopted by the fish tagging community.
The results will add to current knowledge of how surface environment modifications for parasite control can be used most effectively. With salmon lice and amoebic gill disease outbreaks threatening the sustainability of salmon production for human consumption, improved methods to control them are of significant social benefit.
We will tag 24 Atlantic salmon at 4 times of year (a total of 96 Atlantic salmon).
We have thoroughly investigated alternative fish monitoring methods for this research, however salinity acoustic tags were the only option to deliver meaningful data in commerical salmon sea-cages. We selected a small tag size to keep tag:fish weight ratios low, and use up-to-date tagging procedures of minimal intrusiveness.
