Studies on transgenic fish, in contrast to mammals, are still in their infancy. However, it is evident that such fish will not only be of considerable economic benefit to aquaculture but will enable scientists to make quantum leaps in their understanding of the physiological and biochemical mechanisms unique to fish, and of the developmental biology of vertebrates in general.The potential of transgenic fish for research and industrial development is beginning to be widely recognized. This timely volume encompasses the full spectrum of current research on transgenic fish. It will be valuable to many scientists who intend to explore the merits of the technology for the first time.
