This book highlights the ontogenetic development of larval T. ovatus, provides a comprehensive overview of larval rearing of this species. It focuses on the physiological and molecular changes during the early ontogeny of T. ovatus and hatchery and nursery practices. The first seven chapters update the recent development in the hatchery technology in T. ovatus, including feed and feeding, environmental manipulation, hatchery management, and fingerlings in transportation. Chapter eight and onwards decode the possible molecular mechanisms underlying fish development and response to environmental changes and discuss the transcription and expressions of growth and development-related genes in T. ovatus. The last chapters discuss the functional feed additives to the diet and antibiotic usage of T. ovatus juveniles. This book is a valuable resource for researchers, practitioners and students in the aquaculture industry and related fields.
