This book serves as a useful tool for learning about the most common diseases of tilapia (both red and Nile) raised in intensive and semi-intensive systems. It covers both macroscopic and microscopic lesions as well as elements of production and parameters of water quality which are critical to determining the health and disease of these fish.
