Abstract
Genetic programs are an essential component of aquaculture operations and can operate as a management tool to prevent inbreeding as well as facilitate selection for improved traits and increased profitability. A key requirement for the operation of genetic programs is the ability to reproduce select animals in captivity, that is, to have full control of the reproductive process. This study focuses on genetics and reproduction of two important but, before this thesis, taxonomically confused/ indistinct aquaculture oyster species: Pacific oyster Crassostrea gigas or Portuguese oyster, Crassostrea angulata (this unidentified species is hereafter referred to VNO) and on Sydney rock oyster, Saccostrea glomerata with the aim to develop genetic, molecular and physiological tools required for an optimal operation of genetic programs for these species. Scientifically, this study intends to provide knowledge about how long term selection affects genetic diversity, about the role of the endocrine system in oyster reproduction and how this information can be used to set up reliable reproduction and genetically sustainable breeding programs. Research into the above objectives is set out in four data Chapters including: 1) Identification of key genes and peptide hormones associated with reproductive performance of S. glomerata; 2) Analysis of mass selected S. glomerata lines for genetic diversity; 3) Identification of the species identity of oysters cultured in Vietnam and analysis of their genetic diversity and to determine if there is sufficient diversity to initiate a breeding program; 4) Application of the aforementioned discovered genetic and physiological tools to design a trial breeding program for the now identified VNO in Vietnam.
