Abstract
As the capture fisheries have reached the plateau of maximum productivity and fairly stable catches, aquaculture represents the most sustainably efficient way to supply the global meat/protein requirement and become the future of the seafood industry. The world population is predicted to reach 9.7 billion by 2050, hence the demand for high quality protein will continue to grow. An increasing focus on new species and improved aquaculture technologies may help ensure the future global food security. Yellowtail kingfish (YTK), Seriola lalandi, is one of the more recently emerged marine aquaculture species and is considered to have great potential as a species for aquaculture in both sea cages and land based recirculating aquaculture systems worldwide. Genetic improvement through selective breeding is one of the most promising ways to increase aquaculture production including kingfish and improve the quality of the products. The operation and efficiency of genetic improvement programs for kingfish can be supported by the use of molecular marker technologies to identify 1) population structures (and potentially candidates to form or augment the base selected populations), 2) establish pedigrees, 3) achieve more precise genetic parameter estimates and 4) conduct selection on favourable traits using genomic predictions of breeding values. This PhD study aimed to develop new molecular resources to support and enhance selective breeding of yellowtail kingfish using DNA markers targeting the aforementioned four goals.
