Fish supply about 60% of the animal protein eaten in Bangladesh, and almost all of the fry stocked in the country's ponds now come from hatcheries rather than from the wild. That shift rests on induced breeding: hormone treatment that brings carp into spawning condition, producing the seed farmers need as it is required.
A first-hand account from a commercial hatchery in Jashore follows carp breeding through a full production cycle, from the brood ponds to bags of fry loaded onto a truck. It explains why hormones are needed, how brood fish are conditioned and selected, application of common inducing agents, and how spawning, incubation and early rearing are managed. It also looks at what limits hatchery performance in practice, where poor record-keeping, unclear broodstock lineage and everyday problems such as power cuts affect the quality of the seed farmers receive.
An Artemia Session was held on 5 June at the World Aquaculture 2026 conference in Singapore. The session was facilitated by the International Artemia Aquaculture Consortium and covered the outcome of the World Bank PROBLUE Artemia Study Accelerating Brine Shrimp Artemia Aquaculture Production and Conservation for a Resilient Blue Economy.
The session featured case studies from China, Bangladesh, Thailand, Uzbekistan, Iran and Kenya. Presentations (PPTs and videos) from the session are available for download, and video presentations are available for viewing online.
NACA has scoured the internet and put together a Free Bookshelf page with links to all the free aquaculture manuals and technical publications that we could find. These include manuals by NACA and NACA Lead Centres such as SEAFDEC AQD, by FAO, and by other institutions from around the world.
The list can be filtered by topic, so it’s easy to find manuals relevant to your interest. But since they’re free, why not collect them all? In the coming days we may also add links to free magazines and podcasts that we feel are worthy of your attention.

A beautiful PDF poster by Tienthavorn et. al on the "Diversity of Mountain stream fishes in Moei and Khwae Yai River Basin, Tak Province, Thailand" is available to download from the link below. According to the authors, "Fish surveys were conducted at 30 sampling stations, yielding at a total of 77 species belonging to 46 genera, 17 families and 9 orders. The Khwae Yai river basin contained 31 species representing 23 genera, 15 families, 8 orders. In contrast, the Moei river basin contained 54 species representing 42 genera, 14 families, and 8 orders."
