Aquaculture and Aquatic Resources Management

Aquaculture continues to gain immensely from an increasing application of genetics and biotechnological tools, particularly in characterizing the wild genetic diversity of fish stocks, and genetic improvement of cultured stocks. However, such applications are still lagging behind agriculture and livestock sectors as most of the cultured fish are still genetically similar to their wild counterparts. More emphasis has to be given to domestication of the stocks with high-performance traits and for adopting appropriate broodstock management strategies to overcome the negative effects of inbreeding and unintentional selection. This course is aimed to provide students with the basic concepts of applied genetics and selective breeding with emphasis on sustainable management of fish stocks, and conservation of genetic resources for aquaculture.

Learning outcomes:

At the end of this course students are expected to:

 Study the basic principles and practices of genetics and its role in fish reproduction and growth;  Acquire fundamental knowledge of population genetic and quantitative genetic terms and techniques related to aquaculture.

 Learn the principles and practices of selective breeding in fish and conservation of genetic resources for aquaculture;

 Practice the analytical genetic technologies most relevant to aquaculture.

Aquaculture production systems are shaped by the availability of land and water resources, inputs (both material and finance) and technology. Sustainable intensification of the production systems have been one of the major priorities for aquaculture managers worldwide. Rapid increase in culture management tools and practices continue to improve aquaculture production, globally. This course familiarizes the students with modern aquaculture systems and practices, and help them evaluate the components and linkages of aquaculture industry.

Modern aquaculture has been gradually evolved over the last 50 years through development of cost-effective culture practices by using scientific principles. These include culture system design, water quality management, genetics, breeding and larval production, fish nutrition and feed technology, and health management.  The objective of this course is to equip students with a thorough knowledge of the underlying scientific principles of aquaculture.

The objective of this course is to provide students with details of appropriate technologies on a wide range of coastal and inland aquaculture systems relevant to the Asia-Pacific region with an assessment of the constraints to, and the potential for their expansion. The course emphasizes to enable students to appreciate the unique characteristics of inland and coastal aquaculture systems and to learn how efficient management is achieved without any adverse environmental effects.

The objective of this course is to enable students to acquire a sound knowledge of the reproductive biology, breeding behaviour and larval development of the important cultivable finfish and shellfish in aquaculture. The course will familiarize them with specific hatchery techniques including broodstock management, larval rearing, feeding and nursery rearing protocols. The course also endeavours to provide skills necessary for hatchery managers through practicum and on-field training.
