Presents information that can be useful to facilitate the aquaculture of a wide variety of food species. Operation of an economically successful aquaculture venture depends upon the complete life cycle of a species occurring in captivity. Possible solutions to how such complete control of life cycles of important food organisms might be accomplished are presented in each chapter. Whereas this volume (Part A) deals with Seaweeds and Invertebrates, a compendium volume (Part B) deals with Fishes.
