PREFACE
In finfish aquaculture, successful larval rearing and seed supply require the understanding
of fish biology in early life history and technological practice in hatcheries. Hatcheries
produce larval and juvenile fish primarily to support the aquaculture industry where fish are
transferred to on-growing systems or supply juvenile fish for stock enhancement in wild.
Aquaculture continues to grow more rapidly than all other animal food-producing sectors.
The gap between seafood supply and market demand suggests a great potential for
aquaculture development to meet the needs of seafood consumers. In aquaculture, larval fish
rearing is a bottleneck to supply sufficient quantity and high quality of fingerlings for grow-
out production. In the past decade, marine finfish larviculture techniques have quickly
advanced. Feeding regimes and culture systems have been greatly modified to improve
hatchery performance and efficiency. While the use of live food organisms, especially at first
feeding, is still obligatory in most marine fish larvae culture, super-intensive rotifer culture
using algal paste has improved cost-effectiveness in hatchery operation. Weaning of fish
larvae to formulated feed at a later stage of development is easily achieved by co-feeding
formulated feed with live food. Larval deformity and cannibalism are a challenge in some fish
species, but system innovation and management strategies have dramatically reduced their
negative impact in larval fish rearing.
This book deals with larval fish aquaculture for both marine and freshwater species. It
aims to provide comprehensive references on larval fish aquaculture. Specifically, it attempts
to update the recent development in larval fish feed and feeding, environmental manipulation
and hatchery management and to suggest future research needs for improvement of
production efficiency in larval fish culture. An international team of larval fish experts from
leading research institutes and universities in the world has been involved in writing this
book. The main reason to write such a book is the lacking of a comprehensive book covering
major issues in larval fish aquaculture from environmental, biological and managerial
perspectives. This book consists of eight chapters and each chapter stands alone to discuss a
particular issue(s) relevant to larval fish rearing. A total of 14 contributors from France, Italy,
Portugal, Singapore, Spain, and United States provided reviews and summaries in each field.
The organization of book is to start from environmental factors including temperature,
salinity and light, and then to go through the major biological and managerial issues in larval
fish rearing including live feed production, feeding and digestion, gas bladder development,
metamorphosis, cannibalism control and weaning strategies. The information in this book is
by no means complete. It is hoped that this book will become a useful reference text for

researchers and hatchery managers advancing knowledge in larval fish rearing and a
supplementary textbook for advanced courses in larval fish biology and aquaculture. All the
authors responded positively when they were invited to contribute. I express my sincere
gratitude to authors for their commitment in contributing chapters and the valuable
information presented.
