Postlarvae evaluation key to controlling shrimp diseases

Establishing postlarvae quality has become one of the most important aspects in controlling diseases in farmed shrimp. Initial microbial testing can ensure viruses and other pathogens are absent from the animals.

Feed trays or broadcasting?

At higher stocking densities, the application of all feed via feed trays often results in feed being dropped outside and/or underneath the trays.
