Until now, many working in a hands-on capacity in the area of aquaculture have not known what the benefits of this work could be to them. This important new book redresses this situation, providing clear details of the available scientific information and the direct application of techniques under simple and practical situations.AquacultureAquatic animalsGeneticsAquaculture.Aquatic animalsGenetics.639.3639.8Lutz Charles Gregory1957-881322MiAaPQMiAaPQMiAaPQBOOK996208270503316Practical genetics for aquaculture1968251UNISAEbook
