Biomedicines and their role in fish health management

Abstract

The present study reviews the role of plant and animal originated biomedicines and probiotics in the field of aquaculture. Many herbal and animal originated extracts prove their potential as anti stress, antioxidant, antibacterial, anti fungal and viral, appetite stimulator, potent immunomodulator and growth promoter. These herbal extracts and animal originated extracts stimulate the growth and immunity of fishes and they reduce the cost of feed as they are easily available and cheap feed ingredients. They reduce the chances of emergence of pathogens which may cause serious threat to fish health and environment. Yet the diseases, pathogens and pest can be treated with chemicals and antibiotics but due to their residual side effect and bio magnification in the body of fish forces the researchers to search suitable alternatives for healthy fish, environment and sustainable fish production.
