Research performed at the Aquatic Facility of the Centre for Veterinary Medicine and Animal Science, focuses on the biological evaluation of novel feed ingredients in freshwater fish.

The laboratory uses several principal methodologies in studies within fish nutrition and physiology:

  • Apparent digestibility studies with inert indicator method
  • Growth performance trials
  • Nutrient retention
  • Amino acid uptake and stress parameters in blood plasma
  • Intestinal health
  • Digestive enzymatic response
  • Intestinal microbiota analysis

In addition, when post-prandial amino acid levels from fish fed different feed sources and stress parameters are being monitored, this is done with dorsal aorta cannulated rainbow trout. The use of cannulation technique and smaller experimental tanks specifically made for this type of studies, allows for serial blood sampling without causing handling stress that typically occurs during conventional blood sampling.
