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. PART 3 gives extremely detailed and comprehensive, but understandably written methods for all stages of breeding the egg-scatterers - usable even by beginners! It tells how to hold and condition breeders (including diets), set them up for spawning, detect eggs, look after larvae, give the first feed (with food options), raise fry, maintain water quality, deal with health issues etc. This section is based on the egg-scatterers, but is also used as a technique guide and reference for all other species because there is so much common ground between them. Strongly recommended in conjunction with PART 4, for both hobbyist and commercial breeders.
