Immune System and Nutrition in Fish

Abstract

Fish have a complex immune system consisting of various defense mechanisms to protect their bodies from disease-causing organisms and external threats. While fish's immune system shares some similarities with that of humans, it also has some differences. Understanding and researching the immune system of fish in recent years has become crucial for combating infections in both natural habitats and fish farms. The health of fish depends not only on environmental factors but also on the strength of their immune systems. In fish farms, the risk of infectious diseases spreading increases due to high fish density and limited living spaces. Therefore, fish producers employ various methods to strengthen the immune system of fish. Immunostimulants play a significant role in this context. These compounds, which stimulate both specific and non-specific immune systems in fish, can enhance resistance to infectious diseases. The immune system of fish can vary depending on species and environmental conditions. Factors such as nutrition, stress, water temperature, and water quality can affect the immune system of fish. Thus, in situations like fish farming or aquarium maintenance, measures such as maintaining proper water conditions, providing balanced nutrition, practicing hygiene, and implementing disease prevention strategies should be taken into account to support the health of fish.
