TEST PROCEDURES
INTRODUCTION
Proper control of water quality is an essential part of successful aquaculture operation.
Immediate test results provided by on-site water analysis equipment can confi rm a healthy
environment, or give early warning signals for required treatment.
1. Develop a routine testing schedule.
2. Keep records! Historical data is extremely important if treatments are required. Note
environmental conditions, fi sh activity, feeding habits, etc.
3. Observe fi sh to note any particular behavior or feeding rates, as this may be a sign
of stress.
4. Stable characteristics, such as alkalinity and hardness, do not have to be tested as
frequently as ones that fl uctuate, such as ammonia nitrogen, nitrite nitrogen, pH,
dissolved oxygen and temperature. Keep in mind that these factors fl uctuate throughout
the day and in some cases are interdependent.
5. Be alert to sudden changes in one factor, as it may be a clue to perform further analysis.
