This is one of ten eBooks on the commercial production of ornamental fish. It is based predominantly on the author's 30 years of experience, mostly on his own farms. While a few of the eBooks are purely commercial, others, particularly those on breeding, will also be helpful to hobbyists, understandable even by beginners. The following description is provided as a guide. Although the name doesn't suggest it, a lot of this section is also of potential interest to hobbyist breeders, notably such topics as culturing infusoria and other live foods, making glass fish tanks, hatching brine shrimp, making artificial spawning media, how to make peat extract, methods for encouraging or inducing spawning (including hormone injection), biological filtration etc. Potentially of interest to both hobbyist breeders and commercial breeders.
