    Abstract

    Aquaculture is one of the fastest growing animal food producing sectors in the world, accounting for almost half of the total food fish supply. Sustainable larval production is vital to the success of aquaculture. Non availability of healthy, uniform sized, quality seeds in sufficient quantities have always been a concern in ‘capture based aquaculture’ where seeds are sourced from the wild. The above issues can be addressed through ‘hatchery based culture’ systems that can ensure the availability of quality seeds in required quantities. In hatcheries, live feeds play a key role in deciding the survival, growth and development of the larvae. Among the different live feeds, Artemia are widely used as the starter diet in larviculture. To lessen the dependency on natural Artemia sources and reduce the larval rearing expenses, identification of potential strains various formulated diets were tried as alternatives. But, due to reduced preference/acceptability by the larvae, water quality deterioration, etc. their acceptance got reduced in larviculture. In this scenario, a detailed study on native Artemia recourses to develop/ identify suitable superior candidate Artemia strain for use in larviculture is vital for the development of Indian Aquaculture industry. In the study, an extensive survey was conducted along the East (West Bengal, Orissa, Andhra Pradesh and Tamil Nadu) and West regions (Maharashtra, Gujarat and Rajasthan) of the Indian subcontinent for the presence of Artemia populations. Artemia samples were collected from different natural hypersaline habitats along the North West (Mithapur- GMJ & Nanganvadi- GNM), South West (Tamaraikkulam-TNM & Tuticorin- TTJ) and South East (Kelambakam- CKF, Vedaranyam- VDA & Marakkanam TMM) coasts of the Indian subcontinent during 2008 to 2010. In addition, A. franciscana strain (SFB) from San Francisco Bay procured from commercial suppliers and strains of Artemia tibetiana (TBS) and Artemia salina (ASL) received as a gift from the Artemia reference Center Ghent, Belgium were also used as reference strains in the study
