There has been an explosion of research in this area, and now genetics and biotechnology are making a significant impact on aquaculture and fisheries, although potential for much greater progress exists. When improvements from biotechnology are considered, most people think of the impact on aquaculture and not the impact on fisheries. I have tried to address, as the title of this book reflects, not only biotechnology in aquaculture but the interrelationships with fisheries as well. There are several reasons for this. The biochemical and molecular genetic tools that can be applied in aquaculture are equally important for studying population and conservation genetics in fisheries. The goals of aquaculture and fisheries are often portrayed as antagonistic; however, that should not be true and the two cannot be separated because of their interrelationships and impacts on each other. If applied properly, aquaculture has the potential to relieve pressure on natural populations and have positive environmental effects. Natural populations are the ultimate gene bank for future aquaculture application and should be vigorously protected. We must also face the fact that some sport-fish populations now exist in such urban environments, or are so overexploited and artificial, and exist in such altered environments, that anglers could benefit from the same genetic enhancement for these sport populations as is utilized for aquacultural application, without concern for damaging something natural. The concepts in the book are illustrated with numerous research examples and results in an effort to teach, relate theory with reality and provide a strong review of the current status of these biotechnological topics. Early in the book phenotypic variation and environmental effects are addressed. Sometimes we become lost within the nucleus, and temporarily lose sight of the fact that the environment can overshadow genetic effects. Therefore, whether it be traditional selective breeding or biotechnology, we must be aware of these environmental effects and how to control them to generate realistic genetic information and maximize its useful application. In the chapter addressing aspects of population genetics, I often rely on data from organisms other than fish and shellfish. There is not a tremendous database from fish, and some of the examples from other organisms point us towards concepts and observations that are very relevant to aquatic animals and should be more thoroughly examined in aquatic organisms. The latter part of the book focuses on various aspects of transgenic biotechnology. Obviously, at present, this topic can be highly emotionally charged. Data are often not yet available to support the views of those who are strong proponents or opponents of transgenic biotechnology. Various viewpoints and then discussing these perspectives with as many examples of actual data as possible to help us to predict the true benefits and risks of transgenic as well as other types of biotechnology.
