Dear Colleagues,

We are pleased to invite you to contribute to the section collection “ Physiology and Biochemistry ”.

Fish physiology and fish biochemistry are two interconnected fields of study that focus on understanding the biological processes, functions, and chemical composition of fish species. Both fish physiology and fish biochemistry are fundamental to understanding the health, growth, and survival of fish species. They play a crucial role in aquaculture practices, fisheries management, and conservation efforts to ensure the sustainable use of fish resources and the preservation of aquatic ecosystems. Additionally, research in these fields contributes to our broader understanding of vertebrate physiology and biochemistry, as many physiological and biochemical processes in fish are comparable to those found in other vertebrates, including humans.

Fish physiology is the study of how various biological systems and functions work in fish species. It examines the mechanisms that allow fish to survive, grow, reproduce, and respond to their environment. The focused area of this issue but not limited to Respiration: The study of how fish obtain oxygen from water and exchange gases in their gills. Circulation: The examination of the fish cardiovascular system and how blood is pumped through the body. Osmoregulation: The investigation of how fish maintain the proper balance of salts and water in their bodies. Digestion: The study of how fish process and assimilate nutrients from their food. Reproduction: The exploration of the reproductive processes and strategies in different fish species. Sensory Systems: The examination of how fish perceive their environment through senses such as sight, smell, and lateral line sensing. Fish biochemistry is the study of the chemical processes and substances that occur within fish organisms. It focuses on the molecular and cellular levels of fish biology and how different biochemical pathways contribute to their overall function. Metabolism: The study of the chemical reactions that occur in fish cells to produce and utilize energy. Enzymes: The investigation of biological catalysts that regulate biochemical reactions in fish bodies. Proteins and Amino Acids: The examination of the role of proteins and amino acids in fish growth, development, and immune function. Lipids: The study of fats and lipids in fish, which are important for energy storage and cell membrane structure. Carbohydrates: The exploration of the role of carbohydrates as an energy source in fish. Hormones: The investigation of chemical messengers that regulate various physiological processes in fish.

We look forward to receiving your contributes.
