The idea for this book was initially conceived in the International Symposium on “AQUAGAMETE: Reproduction of Aquatic Animals” held in the Joint Meeting of the 22nd International Congress of Zoology and the 87th meeting of the Zoological Society of Japan, which was held from 14th to 19th November 2016 in Okinawa, Japan. Three years have passed since the initial planning, and we have developed the book ideation. In order to introduce up-to-date knowledge on the reproduction systems of various aquatic animals from basic biology to aquaculture technology, we invited up-and-coming researchers to contribute. This book consists of 17 chapters and a foreword that details the history of spermatology to be read before the main chapters. Finally, the book covers the reproductive systems of both sperm and egg in cnidarians, annelids, arthropods, mollusks, echinoderms, ascidians, elasmobranchs, teleosts, and amphibians. Four chapters focus on the technological and aquaculture aspects, in particular relating to fishes.
This book is designed for people who are neither experts/well-read/knowledge-able in the field of reproductive biology nor aquaculture. The assumed readers are graduate students and postgraduates in biology and agricultural sciences and also non-academics who are interested in the field.
