Captive production of Gangetic mystus (Mystus cavasius): A guide for farmers

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.

Report of the 23rd Asia Regional Advisory Group on Aquatic Animal Health

This report summarises the proceedings of the 23rd meeting of the Regional Advisory Group on Aquatic Animal Health, held 14-15 November 2024 by video conference. The role of the group is to review trends in disease and emerging threats in the region, identify developments in global disease issues and standards, to evaluate the Quarterly Aquatic Animal Disease Reporting Program and to provide guidance on regional strategies to improve aquatic animal health management.

Videos available: First International Artemia Aquaculture Consortium Conference and Members' Meeting

The first ever IAAC conference was a free half day event held in Ostend, Belgium on 9 September, as a prelude to Larvi 2024, which ran from 9-12 September. The conference featured twelve presentations introducing the IAAC and providing an overview of many of the issues surrounding Artemia, including management of salt lakes habitats that still provide the bulk of global Artemia supplies, Artemia biodiversity, hatching optimisation, and aquaculture of Artemia biomass in tanks and ponds. Video recordings of most will be posted shortly (the programme below will be updated with links). Video recordings of the presentations are now available on the NACA YouTube channel.

The first IAAC Members’ Meeting was held in the afternoon following the IAAC Conference. The proceedings involved two panel discussions, by the Academic Sector and Private Sector respectively. The panels included remote members participating via Zoom.
