“…For example, the rainbow trout is not only studied with regard to its economical interest but is also a model for more fundamental research in carcinogenesis, toxicology, comparative immunology, physiology and others (Thorgaard et al, 2002). Several topics are investigated in parallel in different species.…”

Teleost fish, which roughly make up half of the extant vertebrate species, exhibit an amazing level of biodiversity affecting their morphology, ecology and behaviour as well as many other aspects of their biology. This huge variability makes fish extremely attractive for the study of many biological questions, particularly of those related to evolution. New insights gained from different teleost species and sequencing projects have recently revealed several peculiar features of fish genomes that might have played a role in fish evolution and speciation. There is now substantial evidence that a round of tetraploidization/rediploidization has taken place during the early evolution of the ray-finned fish lineage, and that hundreds of duplicate pairs generated by this event have been maintained over hundreds of millions of years of evolution. Differential loss or subfunction partitioning of such gene duplicates might have been involved in the generation of fish variability. In contrast to mammalian genomes, teleost genomes also contain multiple families of active transposable elements, which might have played a role in speciation by affecting hybrid sterility and viability. Finally, the amazing diversity of sex determination systems and the plasticity of sex chromosomes observed in teleost might have been involved in both pre-and postmating reproductive isolation. Comparison of data generated by current and future genome projects as well as complementary studies in other species will allow one to approach the molecular and evolutionary mechanisms underlying genome diversity in fish, and will certainly significantly contribute to our understanding of gene evolution and function in humans and other vertebrates.

“…Salmonid fish of the genera Oncorhynchus and Salmo attract the attention of both researchers and the general public, on account of their biological characteristics and wide use in sport and recreational fishing, aquaculture, and research (see examples in Thorgaard et al 2002). Salmonids are particularly known for their extensive genetic and life-history variation, resulting in part from their homing ability during spawning, with localized sub-populations being adapted to different sites and environments within a river system (Dittman and Quinn 1996;Garcia de Leaniz et al 2007).…”

Wilson et al. 1994;Réale et al. 2007). Notwithstanding a certain lack of consensus in terminology, the evolution of these analogues of human personality has evoked considerable scientific interest. Among the questions raised are by which mechanisms behavioural syndromes are inherited, how the variation is maintained, which circumstances benefit different complex phenotypes, and what are the costs and benefits of limited plasticity imposed by more or less fixed trait associations (DeWitt et al. 1998;Koolhaas et al. 1999;Sih et al. 2004; Dingemanse and Réale 2005;McElreath et al. 2007;Réale et al. 2007;Wolf et al. 2007). Furthermore, in the barn owl (Tyto Alba) melanin-based colouration is associated with several behavioural, morphological and physiological characteristics that have been linked to stress coping ability (Almasi et al. 2008).Based on observations that HR and LR trout differed in melanin pigmentation our hypothesis was that spotted fish, in the closely related specie Atlantic salmon (Salmo Salar), 5 would show a lower cortisol reponse to stress when compared to a non-spotted group of individuals. Furthermore, several documented changes in the behaviour of the two trout lines made us predict that also behaviour would differ between groups of spotted and non-spotted fish. The main focus of this study was therefore to test the hypothesis that there exist an association between melanin-based pigmentation and hypothalamus-pituitary-interrenal (HPIaxis) reactivity in salmonid fish. Furthermore, we tested the prediction that behavioural differences are present in two groups of fish chosen divergently on melanin pigmentation. Materials and methods Quantification of melanin-based colorationIn the studies described below, photographs of experimental fish were captured with a Canon EOS 450D digital camera and transferred to a computer for further analyses of melanin-based coloration. Prior to photography, each fish were sedated in 200 mg/l MS-222 and placed adjacent to a measuring tape with millimetre resolution, allowing for an accurate estimation of the area where spots were counted.
