The Biotechnology Department has developed a method to determine cortisol content in the fish slime to establish the degree of stress.
It is imperative that the fish suffers as little stress as possible in the production line with respect to animal welfare, but also because stress impacts eating and growth factors. This is partly because cortisol increases metabolic change and, hence, the need for energy.
Moreover, research has demonstrated that fish stress can cause deteriorating immune defense, so it becomes more susceptible to disease, and this stress can lead to increased mortality rate.
Stress research are conducted when the fish is transported, vaccinated etc. in order to see how the it is impacted while being handled.
