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. This section gives different options in facility design, and production methods and strategies for different circumstances, with advantages and disadvantages for each. The section includes detailed descriptions and illustrations of 3 production layouts: a small, home-sized production set-up, a medium sized operation in a large insulated shed, and a large farm layout. This section is suited to commercial breeders and producers.
