Consumers are now able to understand the negative effects of chemicals and are shifting to natural products. Natural products such as plant products are now being used to reduce stress, promote growth, and increase immune response in fish and shellfish. Some of these products are alkaloids, flavonoids, pigments, phenolics, terpenoids, steroids, and essential oils. In this experiment, we wanted to examine few Indian herbs such as, turmeric, garlic, and chili in-vivo to modulate stress and immune response in fish, tilapia. Fish were fed with these herbs as additives and treated in two different conditions: controlled and stressed. In the stressed group the fish were crowded in tanks so that their optimal density for space is exceeded. Different physiological and biochemical parameters such as, condition factor, blood glucose, spleen somatic index (SSI), plasma protein, packed cell volume (PCV) and macrophage respiratory burst activity were measured. The data indicate that these herbs have positive effects on the reduction of stress. These neutraceuticals can be used in aquaculture industry to reduce stress related complexities such as, low growth rate, disease susceptibility, and high mortality.
