Patterns of genetic diversity in snakehead gudgeons (Channa spp.) in Southeast AsiaEleanor Adamson PhD 2006 - 2010 
Faculty Institute for Sustainable Resources/Faculty of Science and Technology Supervisor/s Aspro Peter Mather, Dr Andrew Baker Thesis Abstract Over three billion tonnes of freshwater fish are harvested from the Lower Mekong Basin every year. This provides a significant source of income for 70% for the inhabitants of the Mekong Basin, many of whom are subsistence fishers or farmers. Freshwater fish are also the primary source of protein in mainland Southeast Asia, and as there is no alternative protein source the sustainability of Mekong fish stocks and security of the Lower Mekong Basin fishing industry is a high priority.
Snakehead fishes (Channa species) are of high economic and social importance throughout Southeast Asia. Despite their widespread use as a food resource, these fish stocks are not managed. Nothing is known about stock structure for Channa species and there is confusion about its taxonomy. This project will use molecular biology to examine this taxonomic uncertainty, and will assess stock structure of the two most economically important Channa species across their natural distribution in the Southeast Asian region, focusing on Thailand, Laos, Cambodia and Vietnam. Data will provide foundations for developing effective stock management practices in the future. |
