Immunostimulants – The name says it all. It is a chemical drug that is used to the increase the innate immune system and growth rate in Aquaculture.
How did it start?
Due to the increase in Aquaculture farming and using of various drugs and artificial chemicals, diseases frequency rate also increased to a great extent which is resulting in poor growth rate and immune system of shrimp and fishes. Antibiotics, chemotherapeutics, vaccinations have been used extensively to control the diseases and neither of it worked as a effective strategy to reduce it. Then a alternative strategy has been proposed that is to strengthen the immune system of the aquatic species by Immunostimulants. It is said to be the promising way to decrease diseases in aquatic species.
Immunostimulants are mostly extracted from Bacterial derivatives, Yeast derivatives, Algal derivatives, Animal and plant extracts, vitamins and hormones
Mostly used Immunostimulants:
β-Glucans : These are from higher plants and yeast cell wall. The can be either injected or fed. Several Glucan products are used as supplements in fish feeds
Muramyl dipeptide: are used for the enhancement of antibody activity
Levamisole are used for the stimulation of pathagocytic activity of macrophages and neutrophils.
Other Immunostimulants include Vitamin C and E, Microorganisms, herbs,
