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. Concise breeding methods for over 130 species/varieties of major commercial families. Includes breeding tank size, water chemistry and temperature, breeding style, spawning tank set-up, grouping of breeders, and a general comment on ease or difficulty of breeding and commercial production, and market demand. Probably more of commercial value, but may be of interest to some hobbyist breeders.
