The Mariculture Division is at the forefront of research and innovation, aimed at propelling sustainable mariculture practices for livelihood enhancement and growth of the nation's blue economy. Focusing on cutting-edge technologies for broodstock development, seed production, and farming of economically important finfish, shellfish, other invertebrates, and seaweed species, the Division endeavours to broaden the scope of production systems. Mariculture research spans biology, nutrition, bio-security, health, genetics, and habitat enhancement, complemented by the development of spatial planning, techno-economic models, decision support systems, automation, and digital technologies tailored for mariculture applications. Our notable achievements include pioneering technologies for captive breeding, seed production, and farming >30 species, alongside the establishment of standardized culture systems encompassing Coastal ponds, Tanks, Cages, Pens, Rafts, RAS, and Integrated Multi Trophic Aquaculture (IMTA). The Division has made significant advancements in refining larval-rearing protocols, nursery systems, and mass culture techniques for diverse algal species and invertebrates as live feed for various stages of finfishes and shellfishes. Through extensive demonstrations, training, skilling initiatives as well as knowledge dissemination programs, the division has empowered countless individuals within the mariculture sector, thereby fostering livelihoods and blue economic goals. The Division remains steadfast in its commitment to driving forward the frontiers of mariculture research and facilitating a brighter, sustainable future for our oceans and communities.
