biosecurity
Be aware of the general principles of the concept of bio-security and in particular, the disease prevention rules to be implemented in case of epidemics endangering public health.
Aquaculture hatchery workers are active in the production of aquatic organisms in land-based hatchery processes. They assist in the process of raising organisms throughout the early stages of their life cycle and the release of organisms when necessary.
