Sommario/riassunto |
|
Over recent years there have been major advances in the application of molecular, biotechnological and genetic techniques to a wide range of aquatic species. 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. |
