Advances in Aquatic Ecology and Fish Biology (Volume - 1), edited by Dr. Surjya Kumar Saikia, offers a comprehensive exploration of aquatic ecosystems, fish biology, and sustainable management practices. Topics include the role of silkworm pupa meal in fish growth, the biology of color pattern formation in teleosts, and the challenges posed by invasive alien species to aquatic biodiversity. The volume delves into fish nutrition, sustainable fisheries management, and the impact of climate change on aquatic species. With contributions from prominent experts, it provides valuable insights into the interconnectedness of aquatic environments and the essential role of science in preserving fishery resources. This work is an essential resource for researchers, educators, and practitioners in the field of aquatic ecology and fish biology.
