Shrimp Pond Water Quality Management: Measure, Record and Respond

Water quality is central to shrimp farming because shrimp depend on their surrounding water for respiration and other essential physiological functions. Poor water conditions can affect feeding, growth, health and survival.

The challenge is that pond water changes throughout the day and across the crop cycle. A single reading cannot describe the full condition of a pond.

Which parameters should farmers monitor?

Dissolved oxygen: Oxygen availability can change with time of day, weather, pond productivity and the respiration of shrimp and other organisms.

Temperature: Temperature influences shrimp metabolism, feeding activity and oxygen demand.

pH: pH affects the chemical environment of the pond and can influence the proportion of unionised ammonia in water.

Salinity: Changes in salinity may affect shrimp osmoregulation, particularly when changes occur rapidly.

Nitrogen compounds: Ammonia and nitrite should be assessed as part of a broader water-quality management programme. Risk depends on concentration, water chemistry and farming conditions.

Build a consistent monitoring routine

Use suitable, maintained instruments and follow their operating and calibration instructions. Record the measurement time, pond number, result, weather and any management action taken.

Monitor more closely when conditions change—for example, after heavy rain, unusual feeding patterns, equipment failure or abnormal shrimp behaviour.

Do not react to one number in isolation

Interpret readings alongside trends, shrimp behaviour, feed-tray observations and recent management actions. If a result is unusual, confirm it where appropriate and seek technical advice before applying corrective inputs.

Practical checklist

  • Measurements taken at consistent, useful times

  • Instruments checked and maintained

  • Results recorded by pond

  • Unusual readings rechecked

  • Actions and outcomes documented

Key takeaway: Water quality management works best when measurement leads to a timely, documented and proportionate response.

Shrimp Pond Preparation: A Practical Checklist Before Stocking

 A successful shrimp crop begins before the first post-larvae enters the pond. Pond preparation creates the conditions for effective water management, responsible stocking and better control of production risks. However, pond preparation is not simply a matter of drying the pond, applying inputs and filling it again. The right approach depends on pond design, soil condition, previous crop performance, water source and the farming system. 1. Review the previous crop Before starting preparation, review the previous crop's performance. Record the harvest result, feed consumption, mortality observations, water-quality problems and any disease investigation. These records can help identify issues that need attention before the next stocking. 2. Inspect the pond bottom After draining, inspect the pond bottom for accumulated organic matter, sludge pockets, damaged liners, erosion and blocked drainage points. Remove waste appropriately and assess whether drying or other corrective measures...

How to Select Quality Shrimp Seed: What Farmers Should Check Before Stocking

 Shrimp seed selection is one of the earliest decisions that can influence crop performance. Poor stocking decisions may create problems that become difficult or expensive to manage later. A farmer should evaluate more than the quoted price or the apparent activity of post-larvae. Seed selection should include source verification, health information, transport planning and appropriate acclimatisation. 1. Verify the source Obtain the hatchery's identity, relevant registration details, batch information and available health documentation. Confirm applicable requirements with the Coastal Aquaculture Authority and other competent authorities. 2. Review health information Ask for relevant test results and documentation for the batch. Where applicable, verify the meaning and scope of claims such as SPF—specific pathogen free. SPF status refers to specified pathogens under defined testing and biosecurity conditions; it does not mean shrimp are immune to every disease. 3. Observe seed cond...
