The Nemipteridae family represents a significant collection of commercially valuable fish species found in the Indo-Malayan Archipelago’s tropical and subtropical regions. Numerous studies have been conducted to document the worldwide decrease in marine fish populations, including Malaysia. Therefore, managing fish is crucial for restoring fish resources, which requires categorising fish populations as distinct entities or stocks. This book identifies fish species within the Nemipteridae family by showcasing the integration of morphometric and molecular methodologies, and phylogenetic relationships. The objective is to generate a comprehensive and contemporary taxonomy and population stock structure of these species, thereby supplementing the existing document. It provides a chance to enhance comprehension of the interrelationships among these factors that can yield mutual advantages for scientists and local populations. Furthermore, this book also addresses contemporary challenges that impact identification approaches. The book also discusses the restoration and preservation of fishery resources in Malaysia, which are experiencing a decline as a result of excessive exploitation. This can be achieved by the utilisation of both traditional and modern identification methods, thereby safeguarding the survival of these resources for the benefit of living organisms. Additionally, this book may serve as a reference by showcasing Malaysia’s natural riches, particularly its fish and introducing them to the world. The book Discover Nemipterid Fishes: Morphometric and Molecular Approaches is structured into five parts that encompass several subcategories. This book is highly recommended for those engaged in the study, research and professional applications of this particular topic.
