About The Book

Nursery Biofloc systems for culturing information are often fragmented and difficult to find in a practical manner. Furthermore, many more technical information on the nursery rearing of vannamei was gathered by trial and error. This book attempts to fill those voids, allowing stakeholders to deploy Biofloc-based culture in expanded vannamei production with greater success. The major goal of this book is to compile all of the essential facts and considerations needed to design and adopt nursery systems using biofloc technology in one place.
