Cobia (Rachycentron canadum), commonly known as black kingfish, lemon fish or ling, is a fast-growing, warm-water pelagic finfish that has emerged as one of the most promising candidate species for marine cage culture. Prized for its firm, pinkish-white flesh and high market demand, cobia combines rapid growth, a favourable feed conversion ratio, adaptability to captive breeding, and suitability for offshore cage farming (Abdul-Nazar et al., 2019). Globally, China and Taiwan dominate production, while in India the first successful captive breeding and seed production was achieved in 2010 by the ICAR-Central Marine Fisheries Research Institute (CMFRI), Mandapam Regional Centre (Gopakumar et al., 2011). This article presents an overview of the biology, habitat and distribution of cobia, followed by a systematic account of its culture practices, spanning broodstock development, induced spawning, larval rearing, nursery and grow-out phases, harvesting, and the major disease and management challenges faced in cage aquaculture. The discussion underscores cobia's potential to strengthen and diversify India's mariculture sector, while highlighting the biosecurity and site-selection challenges that must be addressed for sustainable expansion.
