Can advances in fish immunology help improve the health of fish in aquaculture?

Secombes C.J

Control of disease to maintain fish health is important for the continuing success of the Scottish aquaculture industry. Of the different approaches that can be adopted, it is clear that vaccination offers a prophylactic treatment with limited environmental issues, and is thus a method of choice against ubiquitous diseases accessible to the immune system. Whilst some vaccines have been proven to be tremendously successful others have not, and ways to improve vaccine performance and to accelerate their development are needed. Over the last few years knowledge gained about the complexity of the fish immune system has increased enormously, in large part due to the availability of sequenced fish genomes. The many immune genes discovered will allow new approaches in fish vaccine development, as highlighted in this talk. The potential to boost vaccine performance, to manipulate the immune system in a more controlled fashion and to measure more precisely the type of response being elicited, are examples of ways in which these molecules can now be used to the benefit of fish health.

For the purposes of this study seven sampling campaigns were carried out during the period 2007-2009 at Rías Baixas. Two toxic episodes caused by Pseudo-nitzschia spp. were recorded (October 2007, July 2009). Relatively high abundances of the red-tide dinoflagellate Noctiluca scintillans were observed in July 2008.  An approach that involves, 1) remote sensing techniques using Medium Resolution Imaging Spectrometer (MERIS), 2) application of immunological methods and 3) experiments in phytoplankton cultures,
