Needless to emphasis that it is paramount importance in aquaculture that it has to be practiced within the boundaries of its sustainable limits. Advanced and eco-friendly techniques in aquaculture could be cleverly adopted in order to develop 'technically feasible' and 'economically viable' packages of aquaculture technologies for adoption in our country. This book covers a wide range of topics coving many techniques starting from the basics such as algal production technique to the latest molecular diagnostic technique such as PCR and the Intensive Raceway System Management which could be of immense use to the fisheries graduates, laboratory/farm technicians, entrepreneurs and others.  This book includes all the essential and inevitable techniques one should know, to be a successful 'aquaculturist' and to manage the systems on scientific lines.
