What role for genomics in fisheries management and aquaculture? 5
Wenne, Roman; Boudry, Pierre; Hemmer-hansen, Jakob; Lubieniecki, Krzysztof P.; Was, Anna; Kause, Antti.
The development and application of genomics has been facilitated in a number of fields by the availability of new methodologies and tools, such as high throughput DNA sequencing and complementary DNA (cDNA) microarrays. Genomic tools are already used in research on commercially important fish and shellfish species. Thousands of expressed sequence tags (EST) are now available for some of these species, and the sequencing of complete genomes of tilapia, cod, salmonids, flatfishes, sea bass and Pacific oyster has been proposed. Microarray technology through simultaneous analysis of the expression of thousands of genes allows the identification of candidate genes involved in the function of multiple physiological, morphological and behavioural traits of...

The genetics of overwintering performance in two-year old common carp and its relation to performance until market size 5
Prchal, Martin; Kause, Antti; Vandeputte, Marc; Gela, David; Allamellou, Jean-michel; Kumar, Girish; Bestin, Anastasia; Bugeon, Jerome; Zhao, Jinfeng; Kocour, Martin.
Using farmed common carp, we investigated the genetic background of the second year overwintering performance and its relation to the performance during the third growing season and at market size. The experimental stock was established by partial factorial design with a series of 4 factorial matings of 5 dams and 10 sires each. The families were reared communally and pedigree was re-constructed with 93.6% success using 12 microsatellites on 2008 offspring. Three successive recordings (second autumn, third spring, and third autumn—market size) covering two periods (second overwintering, third growing season) were included. Body weight, Fulton’s condition factor and percent muscle fat content were recorded at all times and headless carcass yield and fillet...

Potential for Genetic Improvement of the Main Slaughter Yields in Common Carp With in vivo Morphological Predictors 5
Prchal, Martin; Bugeon, Jerome; Vandeputte, Marc; Kause, Antti; Vergnet, Alain; Zhao, Jinfeng; Gela, David; Genestout, Lucie; Bestin, Anastasia; Haffray, Pierrick; Kocour, Martin.
Common carp is a major aquaculture species worldwide, commonly sold alive but also as processed headless carcass or filets. However, recording of processing yields is impossible on live breeding candidates, and alternatives for genetic improvement are either sib selection based on slaughtered fish, or indirect selection on correlated traits recorded in vivo. Morphological predictors that can be measured on live fish and that correlate with real slaughter yields hence remain a possible alternative. To quantify the power of morphological predictors for genetic improvement of yields, we estimated genetic parameters of slaughter yields and various predictors in 3-year-old common carp reared communally under semi-intensive pond conditions. The experimental...

Morphological predictors of slaughter yields using 3D digitizer and their use in a common carp breeding program 5
Prchal, Martin; Kocour, Martin; Vandeputte, Marc; Kause, Antti; Vergnet, Alain; Zhao, Jinfeng; Gela, David; Kašpar, Vojtěch; Genestout, Lucie; Bestin, Anastasia; Haffray, Pierrick; Bugeon, Jérôme.
Slaughter yields are traits of high interest especially for fish species sold in processed form like headless carcass or fillets, as well as with regard to increasing consumer preference for easy-to-prepare fish products. However, slaughter yields cannot be measured on live fish and thus their genetic improvement through mass selection is impossible. The usual alternatives are sib selection and/or indirect selection on correlated traits or morphological predictors of slaughter yields. In the present study, we assessed the possibility of using a combination of 3D digitized landmarks and ultrasound measurements in genetic improvement of slaughter yields in common carp. DNA – pedigreed market-size carp (n = 1553 fish) were produced from a partial factorial...

Genetic relationship between koi herpesvirus disease resistance and production traits inferred from sibling performance in Amur mirror carp 5
Zhao, Jinfeng; Prchal, Martin; Palaiokostas, Christos; Houston, Ross D.; Kause, Antti; Vandeputte, Marc; Vergnet, Alain; Bugeon, Jérôme; Bestin, Anastasia; Veselý, Tomáš; Pokorová, Dagmar; Piačková, Veronika; Pojezdal, Lubomír; Genestout, Lucie; Gela, David; Kroupová, Hana K.; Kocour, Martin.
Koi herpesvirus disease (KHVD) is currently the most serious threat to global carp farming. Prevention is a sensible strategy for tackling this disease and improved genetic resistance of carp strains is a desirable breeding goal. To study the potential for multitrait selection, the objective of the current study was to estimate the genetic correlations between KHVD resistance and production traits in Amur mirror carp. A total of 1500 fingerlings from four factorial crosses of five dams and ten sires were challenged with Koi herpesvirus (KHV). Juvenile growth-related traits were collected on the same individuals before the challenge test. Production traits were measured on siblings of the challenged population at different life stages (yearling to market...
