Abstract
The objective of the Atlantic Cod Genomics and Broodstock Development Project (CGP) is to develop breeding programs and fundamental genomics tools which will be used to supply the developing Atlantic cod aquaculture industry in Canada with improved broodstock (www.codgene.ca). The first three major spawning seasons have been completed, including rearing of fish in hatcheries through to transfer of juveniles to seacages. The fourth spawning season, which was the first to include elite broodstock as parent fish, is also completed. Evaluations of progeny have included assessment of family performance related to growth and overall health. In addition, investigations related to cod physiology and immunology have been conducted. Considerable variations among families have been observed. Heritability estimates suggest that the breeding programs will yield improved performance. The CGP has dramatically improved availability of genomic resources for cod. Approximately 158,000 sequences have been submitted to GenBank. A 20,000 element (20K) oligonucleotide microarray is being printed and tested. Development of gene-linked markers and a high density genetic map are ongoing. Marker identification has yielded >4,500 "predicted informative" single nucleotide polymorphisms (SNPs) and >140 microsatellite markers. In addition, social scientists have worked closely with other CGP scientists and industry partners to examine ethical, environmental, economic, legal and social issues related to the CGP. Resources developed by the CGP will enable marker assisted selection, and provide valuable tools for Atlantic cod research.
