PREFACE

In this volume, five species of marine invertebrate animals and finfish with special economic value are introduced to readers, namely, sea-horse (Hippocampus spp.), horseshoe crab (Tachypleus spp.), seacucumber (Stichopus japonicus), scallop (Chlamys farreri), and razor clam (Sinonovacula constricta).

Among these cultured marine organisms, some species, such as scallop, have been well known and especially cultured in some countries for a long time. Others, such as the horseshoe crab are not as well known but have a great economic potential. They are already among those being cultured, although in a limited scale. Thus, the objective of this compilation is to describe the characteristics of these species and their economic potential in order to increase interest among entrepreneurs as well research and development workers in their artificial culture.

The information contained in this volume have been compiled from books, journals, and articles published in China. Thanks are due to the original authors for allowing the translation of the articles into English and their incorporation in this compilation.

This working paper was prepared by Chen Jiaxin and edited by Pedro Bueno and Alessandro Lovatelli.
