    ‘Blond’: a useful new genetic marker in the tilapia, Oreochromis niloticus (L.) (1987)
    Oxford, UK : Blackwell Publishing Ltd
    Aquaculture research 18 (1987), S. 0

    Notes: Abstract. Breeding tests demonstrate that a blond mutant showing a marked reduction of melanin in chromatophores, arising within a laboratory population of Oreochromis niloticus (L.) is due to a single autosomal recessive gene. Possible commercial and research benefits of this character are discussed.

    Biodiversity in aquatic systems in relation to aquaculture (1997)
    Oxford, UK : Blackwell Publishing Ltd
    Aquaculture research 28 (1997), S. 0 
    Details
    ISSN: 1365-2109

    Notes: This paper first considers the perception and dimensions of biodiversity. We suggest that biodiversity can be viewed as a biospatial, hierarchically distributed structure of variability among living organisms with five levels of complexity (and including agricultural systems). Loss of biodiversity, value of biodiversity and knowledge of aquatic biodiversity are reviewed briefly. Methods for measuring biodiversity, especially at the genetic level, are discussed and considerable emphasis is laid on effective population size as a controlling factor in biodiversity.Finally, a range of impacts of aquaculture upon biodiversity are considered, including competitive and introgressive effects from farmed stocks. The development and use of reversibly sterile strains is seen as highly beneficial to both aquaculture and the maintenance of biodiversity.

    Absence of restriction site variation in the mitochondrial ND5 and ND6 genes of Atlantic salmon amplified by the polymerase chain reaction (1995)
    Oxford, UK : Blackwell Publishing Ltd

    Details
    ISSN: 1095-8649

    Topics: Biology
    Notes: There was no restriction site variation in Atlantic salmon mitochondrial DNA in an amplified DNA segment beginning in the ND5 gene and terminating in the ND6 gene, although seven haplotypes were observed when the complete molecule was restricted.

    Population structure in the Atlantic salmon: insights from 40 years of research into genetic protein variation (2005)
    Oxford, UK; Malden, USA : Blackwell Science Ltd
    Journal of fish biology 67 (2005), S. 0

    Notes: Electrophoretic studies of proteins remain a primary source of insight into genetic diversity in many species including the Atlantic salmon Salmo salar, one of the most culturally and economically important fish species of the North Atlantic region. Since 1966, 〉350 scientific papers on protein variation have been published encompassing 25 000+ salmon from over 400 locations in 〉200 river systems across the species’ distribution. Variation has been detected at 30% of the 110 protein loci screened, though most studies examine 〈40. The method has been applied largely to the investigation of population structure and differentiation, but work has also led to the systematic revision of the genus Salmo and remains the primary source of insight into hybridization in the wild with brown trout Salmo trutta. Spatial patterns of differentiation show temporal stability, both within and among river systems, and strongly support structuring of the species into river and tributary specific populations and the designation of European and North American populations as distinct sub-species. They also show widespread regional differentiation within both continents, beyond the marked subcontinental differences between Baltic Sea and Atlantic Ocean populations in Europe. Most of the differentiation probably reflects gene flow and founder events associated with colonization following the retreat of the glaciers from much of the species’ modern range. However, variation at MEP-2* shows strong correlations with environmental temperature, both within and among rivers, and associations with phenotypic performance. This suggests selection is acting on the locus and provides compelling evidence for the local adaptation of populations. Protein studies have led to more population centred management of the species and have been exploited in the discrimination of regional stocks in mixed stock analysis in high seas fisheries, particularly in the Baltic Sea, and as markers for the assessment of stocking success. They have also advanced insight into how the genetic character of populations can be changed in cultivation and the potential impact of salmon aquaculture and stocking on wild populations. The method has been largely superseded by DNA based analyses, but the results remain highly relevant to Atlantic salmon management and conservation and are an irreplaceable data set for studying genetic stability of populations over time.

    Genetics and disease resistance in aquaculture (1998)

    Notes: Disease in aquaculture is a significant problem especially in intensive culture systems. Relatively little effort in combating disease has been expended in developing genetically resistant strains. Nevertheless, the experience available from economically important terrestrial species, the need to use environmentally friendly or neutral production systems and the impressive range of genetic technologies available, combine to suggest that genetic approaches to disease resistance (combined with appropriate husbandry) represent the most effective and attractive way forward.

    Notes: [Auszug] The crucial difficulty in explaining this differentiation by mutation of nuclear genes is that a mutation rate per gamete of 10?2 is inferred from data on skeletal variants and is incompatible with rates of mutation of the order of 10?6 observed by Russell and others. We should note, however, that ...
