1. Defence on Demand : A physiological perspective on phenotypic plasticity in anti-predator traits
Abstract : Almost all species face some degree of predation risk, and, hence, evolution has produced a plethora of anti-predator defences. However, anti-predator strategies require resources, and the prevailing risk of becoming prey is influenced by many factors and rarely constant across time and space. READ MORE

2. Mechanisms of failure and survival in the anoxic fish brain : With focus on the crucian carp
Abstract : Neural responses to anoxia were studied in two fish species, the rainbow trout(Oncorhynchus mykiss) and the crucian carp (Carassius carassius). The rainbow troutbrain reacted to anoxia by a massive release of excitatory amino acids and K+ into theextracellular compartment, in a fashion very much like the brain of mammals duringanoxia.

3. Lipid quality of common carp (Cyprinus carpio) in pond culture
Abstract : There is a large body of evidence that n-3 fatty acids, especially EPA and DHA are beneficial for human health. Content of these fatty acids in fish fillet can be influenced by several factors. This thesis examined differences in lipid content, lipid class and fatty acid composition among three parts of common carp fillets. READ MORE

4. Lipids in common carp (Cyprinus carpio) and effects on human health
Abstract : There is evidence that n-3 fatty acids (FA), especially EPA and DHA, are beneficial for human health. This thesis examined factors influencing FA composition in common carp flesh, sought to develop a procedure for long-term sustainable culture of common carp with improved muscle lipid quality (omega 3 carp) and studied the health benefits of eating such carp in the secondary prevention of cardiovascular disease.

5. Phenotypic plasticity and the evolution of an inducible morphological defence in crucian carp
Abstract : In this thesis, I have investigated factors (cues, benefits, and costs) affecting the evolution of an inducible morphological defence in crucian carp (Carassius carassius). Inducible defences are favoured over permanent defences when prey have reliable cues to detect predators, when defences are effective but costly, and when predation pressure is variable and unpredictable, but sometimes strong.
