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. Information includes the best water chemistry and temperature for breeding, setting up for spawning, the spawning process, early rearing and grow-out, harvesting and packing, with many important breeding and production characteristics specific to the species. Strongly recommended in conjunction with PART 3, for both hobbyist and commercial breeders.
