The recent explosion of research using aquacultural methods relies heavily on knowledge of reproductive and developmental strategies of target organisms such as invertebrates. Meets the growing need for a single volume which outlines the major groups of invertebrate animals with respect to these strategies. Arranged phylogenetically, it covers a variety of species in different phyla and classes. Marine, freshwater, and terrestrial species are included to provide a survey of strategies influenced by habitat and to increase its usefulness as a resource for students or professionals working with native species in different geographic areas. Major experimental models are covered, as are species frequently encountered in field collections and those which can be purchased for embryological study from biological supply companies.
