The Gangetic mystus (Mystus cavasius) is a small indigenous freshwater catfish valued for its taste and nutritional qualities, with high market demand across South Asia. This article offers a practical guide for farmers on the captive breeding and production of M. cavasius, encompassing key stages from broodstock management to grow-out culture. Captive production methods are critical for ensuring seed availability and enhancing the commercial viability of this species. The article outlines protocols for brood selection, hormone-induced breeding, egg fertilisation, larval rearing, and fingerling development, with emphasis on water quality, feed regimes, and optimal stocking densities.

Special attention is given to improving larval survival through early indoor rearing, proper husbandry, and the use of live and formulated feeds. The slow-growing nature of M. cavasius necessitates low-density stocking and extended grow-out periods, typically yielding less than 1 tonne/ha/year. Despite the modest productivity, the species commands strong regional demand at 30–40 g market size. The guide also addresses common health issues and preventive practices, stressing the importance of water quality and early disease intervention. Overall, this article supports smallholder farmers seeking to diversify their aquaculture practices with a high-value indigenous species.
