Objective
The culture of fish is an important European industry. However, there is now a growing awareness that releases of cultured fish for stocking may be ineffective and may also have detrimental impacts on wild populations. In the target species for this proposal, Atlantic salmon (Salmo salar) and brown trout (S. trutta), such effects are well documented, but the physiological and endocrinological mechanisms underlying the domestication process is poorly now. As a consequence, it is not possible to predict with confidence the ecological impact of domestication.
The objectives of this project are:
- To identify how domestication affects the interrelation between physiology and behaviour and how this relates to performance (i.e. growth, survival and reproduction) under natural and semi-natural conditions
- To assess genetic and environmental impacts of cultured fish on wild conspecifics at various life stages through competition and interbreeding
These objectives will met by three complementary approaches:
Physiology and behaviour - Basic performance (Task 1):
The first group of experiments concentrates on comparative physiology and behaviour, with special emphasis on: (i) genetic effects of hatchery selection; (ii) environmental effects of the hatchery; (iii) effects of increased energetic needs. These experiments will reveal how domestication alters some important physiological and behavioural mechanisms.
Source of variation: Effects of phenotypic expression of growth related characters (Task 2):
The second group of experiments includes measurements of heritability and genetic correlations for a number of physiological and behavioural traits that are known to be important for fitness. The measures are crucial for evaluating the potential effects of domestication and their incidence in natural populations.
Ecological impacts on wild populations (Task 3):
The third group of experiments is linked to the previous two tasks as it focuses on the ecological impact of domesticated traits of hatchery fish on wild co specifics in nature.
