In order to meet increasing demand for seafood worldwide Recirculation Aquaculture Systems (RAS) are frequently used. These systems are susceptible to contamination by waste matter including faecal material in the water. It is imperative that this material is removed from the system. The maintenance of good water quality is a pre-requisite to the success of the operation. Negligence in this area will adversely affect animal growth rates and also the economic performance of the system.

Micro-screen drum filters are a popular solution for the removal of this material (Cripps, Simon J. and Bergheim, Asbjørn., 2000). These screens are nominally rated …

In Vitro Enabling Technologies For Use In The Aquatic Environment, Colm J. O'Dowd

O’Dowd, C., Mothersill, C.E., Cairns, M.T., Austin, B., Lyng, F.M., McClean, B. and Murphy, J.E.J. Assessing the mitochondrion as a biomarker of fish tissue damage using g radiation as a stress model in vitro.

There is an ever-increasing need for biomarkers to identify toxic stress in the aquatic environment. Such techniques need to be accurate, expeditious, ethical and economical. Typically, in vitro based platforms fit these criteria however many of these systems often undergo ‘assay drift’ and consequently do not fully represent the real-life situation.

In recent years, there has been growing interest in the mitochondrion and its (dys)function …

Chemical Analysis Of Veterinary Drug Residues In Salmon Tissue, Patrice Behan

Doctoral

The Irish finfish-farming section has increased from 20 tonnes in 1980 to 15,440 in 1997. The sales value of the 15,440 tonnes was £37.5 M where exports were worth approximately £30 M of this. This increasing intensity of fish farming has inevitably been paralleled by increases in disease, which has force the mariculturist to increase the use of chemicals. A major concern with the use of chemicals in mariculture is residues, which may remain in the fish tissue after harvesting and resulting in exposure to the consumer. Under Council Directive 96/23/EC Member States are required to monitor on a routine …
