Celebrating the 10th anniversary of the Amazonian Invertebrate and Vertebrate Studies Group (NEIVA), a research group at the Federal Institute of Education, Science and Technology of Amazonas (IFAM), means celebrating a journey defined by science, researcher training, institutional cooperation, and an enduring commitment to knowledge and the conservation of Amazonian biodiversity. Over the past decade, NEIVA has conducted research to understand Amazonian organisms and their interactions with the environment. The group bridges various fields of knowledge and aligns scientific research with the region’s environmental, social, industrial, and technological needs, with a particular focus on Amazonian aquatic organisms. This book, titled Amazonian Aquatic Organisms: Physiology, Ecotoxicology, Conservation, and Fish Technology, compiles 11 chapters that reflect this journey. The work presents studies and reviews spanning various levels of investigation, from organismal biology and physiology to environmental contamination, biodiversity conservation, aquaculture, and the technological use of fishery resources. It brings together contributions from professors and researchers representing the Federal Institute of Education, Science and Technology of Amazonas (IFAM), the Federal University of Amazonas (UFAM), the Federal Institute of Education, Science and Technology of Acre (IFAC), the Federal Institute of Education, Science and Technology of Espírito Santo (IFES), the State University of Amazonas (UEA), the Nilton Lins University Center (CUNL), and the Manaus Metropolitan College (FAMETRO). Furthermore, students from three graduate programs are listed among the chapter authors: the Graduate Program in Animal Science and Fishery Resources (PPGCARP) at UFAM; the Graduate Program in Veterinary Sciences (PPGCVET), offered in partnership between IFAM and CUNL; and the Graduate Program in Biodiversity and Science Education in the Amazon (PPGBEC), offered in partnership between IFAM and UEA. We also acknowledge the institutional and financial support that enabled the research presented in this collection. In this regard, we highlight the contributions of the National Council for Scientific and Technological Development (CNPq), the Coordination for the Improvement of Higher Education Personnel (CAPES), the Federal Institute of Education, Science and Technology of Amazonas (IFAM), and the Amazonas State Research Support Foundation (FAPEAM), institutions that are fundamental to strengthening science and human resource development in the Amazon. We also thank the universities, graduate programs, laboratories, research groups, and other institutions that partnered with NEIVA and helped expand opportunities for scientific inquiry, knowledge exchange, and academic training. Chapters 1 and 2 present studies on freshwater stingrays—specifically, an investigation into the sexual dimorphism of *Potamotrygon orbignyi* and a discussion on the impacts of polycyclic aromatic hydrocarbons on aquatic environments. These studies highlight the importance of scientific knowledge for conserving ecologically significant species for which major knowledge gaps remain. Chapters 3, 4, and 5 focus on research into the physiology of fish species of economic importance to the Amazon. Thus, the physiology and ecology of Amazonian fish constitute another central theme of the work. Chapters on the influence of temperature on fish physiology, behavior, and reproduction, as well as the ecophysiology of peacock bass (tucunarés) in the Tarumã-Açu River basin, demonstrate the importance of understanding how organisms respond to environmental conditions. Such research is particularly relevant given the environmental changes currently affecting aquatic ecosystems. Fish technology is another key area, highlighted in chapters 6, 7, and 8, showing how scientific research can directly drive innovation. Chapters on protein hydrolysates, gelatin coatings, and antioxidants present strategies to improve the preservation, quality, shelf life, and use of fishery products, adding value to a production chain of great economic and social importance to the Amazon region. Ecotoxicology also plays a prominent role in this collection, featured in Chapter 9. The analysis of contaminant effects, including metals and organic compounds, on freshwater chelonians highlights the risks of environmental degradation. It underscores the need for strategies to monitor, conserve, and manage Amazonian fauna. The work also presents an important dimension related to animal production and aquaculture, through the discussion of shrimp species cultivated exclusively in freshwater (chapter 10). This perspective brings research on biodiversity closer to the possibilities of sustainable production and use of the Amazon’s aquatic resources. Chapter 11 addresses the impacts of pesticides on Amazonian pollinators and invertebrates, highlighting the risks of environmental contamination for biodiversity, ecosystem balance and the conservation of Amazonian fauna. Therefore, the 11 chapters gathered here represent much more than a collection of scientific works. They record a decade of research, training and collective knowledge-building. Each chapter includes students, researchers, advisors and collaborators who helped consolidate NEIVA as a space for scientific production and human resources training in the Amazon. The book contributes directly to Sustainable Development Goals (SDGs) 15 – Life on Land, 12 – Responsible Consumption and Production and 2 – Zero Hunger and Sustainable Agriculture, by discussing the impacts of pesticides on pollinators and Amazonian invertebrates and by highlighting the importance of biodiversity conservation, the responsible use of chemicals and the adoption of sustainable agricultural practices. It also contributes, in a complementary way, to SDG 3 – Health and Well-Being, by addressing environmental risks associated with contaminant exposure. Publishing this work also marks a decade of learning. Over these ten years, questions became projects, projects became data, data became knowledge, and knowledge became new questions. This dynamic is the essence of science and also represents NEIVA’s trajectory. Celebrating 10 years of NEIVA, therefore, means looking back at the path taken, recognizing the achievements and, at the same time, projecting the future. The Amazon continues to present enormous scientific, environmental, social and technological challenges, and the knowledge produced by institutions and research groups in the region itself is essential to face them. May this work represent not only a synthesis of part of NEIVA’s scientific production, but also an invitation to new research, new partnerships, discoveries and the formation of a new generation of scientists committed to the Amazon. Ten years of NEIVA. Ten years of science, training, biodiversity, innovation and commitment to the Amazon. May the next ten years bring even more science to understand, value and transform knowledge about the Amazon.
