Preface

Aquatic ecosystems are critical to the environment and human livelihood, providing resources such as food, water, and recreation. Understanding these systems through the lens of fisheries and limnology is essential for their sustainable management. This book, An Introduction to Fisheries and Limnology, serves as a comprehensive guide to the key concepts and practices in these fields.

Beginning with foundational topics, the book introduces readers to aquaculture and fisheries, setting the stage for deeper explorations into the current status of fisheries in India—a nation where aquatic resources play a vital role in both economy and food security. From there, we delve into the dynamics of freshwater and brackish water ecosystems, discussing important water quality parameters and the process of eutrophication.

Lentic and lotic ecosystems are explored, with insights into how water movement shapes aquatic life. Practical techniques like liming, which enhances water quality, are discussed alongside the classification of fishes, offering an understanding of aquatic biodiversity. Finally, the book examines fishing gears and crafts, emphasizing the tools used in sustainable fishery practices.

This book aims to equip readers with both theoretical and practical knowledge, fostering a deeper understanding of our aquatic resources and how to manage them effectively.
