Protocols of Fish Biology is a comprehensive book specifically designed to meet the Model Curricular requirements of students studying at the UG and PG levels, as well as aspirants preparing for UGC-NET, various certificate, diploma, and degree vocational courses, CSIR-NET, and similar examinations. The book is divided into six units and 47 chapters that cover all aspects of ichthyology, including distribution, evolution, and adaptation, characteristics, classification, physiology, and economic importance of fish. The book provides current information and advancements on the scheme of classification given by Nelson (2016), genomics, and the effects of climate change on fish. Each chapter is labeled with appropriate headings and subheadings in bold. From the majestic migrations of ocean wanderers to the intricate social structures of freshwater communities, this book delves into the fascinating tapestry of fish biology. The book demonstrates the author extensive knowledge, innovative ideas, and lucid style of explaining text clearly and systematically. This book may pique readers interest by transforming the ordinary into the extraordinary and mirroring the depths of knowledge with the ocean.

The anatomy of water, water as a substance, water as a medium, the principles of the hydrologic cycle, the economics of water, and challenges are all covered in the first chapter of this book. The horizon of the tropical world, the environment, particularly the tropical environment, aquatic biome, tropical aquatic bionetwork, concept of biosphere, and tropical limnology are all covered in the second chapter. The third chapter covers the following topics: the origins of lakes, general lake classification, tropical lakes, lake morphometry, morpho-edaphic index, trophic status index of lakes, wetlands, and mangroves in tropical regions. The lotic environment is the main topic of the fourth chapter, which also covers the idea of stream order, the differences between rivers and streams, the river continuum, physical, chemical, and biological characteristics, and adaptations of fish found in hill streams. Chapter five covers the prokaryota, cyanobacteria, freshwater biota, and water-adapted organisms. The sixth chapter focuses on the algal communities Xanthophyceae, Euglenophyceae, Bacillariophyceae, Chrysophyceae, Phaeophyceae (brown algae), and Chlorophyceae. The seventh and last chapter covers the following topics: Protozoa, Porifera, Rotifera, Coelenterata, Annelida, Arthropoda, Crustacea, Aquatic Insects, Mollusca, Echinodermata, and Brachiopodaa.
