SSNS Training Course VET3

 

Water quality analysis for aquaculture

 

Background

The efficient and profitable production of aquatic animals such as fish, crustacean, etc. in aquaculture depends on a suitable environment in which they can reproduce and grow. Those animals live and are totally dependent on the water they live in for all their needs, the major environmental concern within the culture system is water quality. Water quality is the most important factor affecting fish health and performance in aquaculture production systems for many years. Different aquatic organisms have different and specific range of water quality parameters within which they can survive, grow and reproduce. The result is deteriorating water quality which stresses the culture species, and stress leads to poor growth, greater incidence of disease, increased mortality, and low production. Water quality parameters that are commonly monitored and managed in the aquaculture industry include temperature, pH, dissolved oxygen, salinity, alkalinity, ammonia, nitrites and hardness. The purpose of this training course is to provide a practical guide to the monitoring and management of aquaculture pond water.

 

Learning outcome

-          Clearly understand water quality parameters and their key properties

-          Develops skill in the monitoring and management of water quality in ponds and interpretation of water quality data
