Book excerpt: Following a short introduction to the species and its closest commercially viable related species, namely pirapatinga (Piaractus brachypomus) and pacu (Piaractus mesopotamicus), this field guide provides practical information on the culture and reproduction of tambaqui (Colossoma macropomum). As a field guide it aims to support the understanding and dissemination of applicable technologies for the culture and reproduction of tambaqui, i.e. what should be done – as well as when and how it should be done – in order to achieve success in the artificial propagation as well as the fingerling and table fish production stages. The concise technical descriptions in this guide are accompanied by self-explanatory illustrations and a reader-friendly glossary of technical terms, which is important for tambaqui aquaculture farmers.
