Effect of Water pH on Vannamei Shrimp Cultivation
pH measures a solution’s degree of acidity or alkalinity on a scale of 0 to 14. The pH of pond water in good Vannamei shrimp farming ranges from 7.5-8 in the morning and 8-8.5 during the day.
So, what if pond water’s pH could be more optimal? Read more in the following article.

What is pH?
pH is a measure of the acidity or alkalinity of a solution indicated by a logarithmic scale ranging from 0 to 14. pH 7 indicates a neutral condition, a pH less than 7 indicates an acidic condition, while a pH greater than 7 indicates an alkaline state.
How to Check pH
You need a pH test kit, such as pH indicator paper, to determine the pond’s pH in Vannamei shrimp farming. Here are the steps for measuring pH using pH indicator paper or a pH meter that you can follow:
Collect a sample of the shrimp pond water in a clean container.
Dip the pH indicator strip into the water sample or use a pH meter to measure the pH value directly.
Wait for the pH indicator strip to change color or for the pH meter to stabilize its reading.
Match the color of the pH indicator strip to the color chart or read the pH value that appears on the pH meter.
Record and compare the pH measurement results with the optimal pond pH range for Vannamei shrimp farming.
If the pH is outside the optimal scope, take the necessary steps to adjust it.
Effect of Water pH on Vannamai Shrimp Cultivation
The pH level of pond water can significantly impact shrimp’s health and growth. A pH level that is too low or too high can cause stress on the shrimp, thereby reducing the growth rate and making it more susceptible to disease.
The low pond water’s pH can also cause the shrimp skin to become porous and soft due to the disruption of changing new skin. Also, shrimp can die if the pond water pH is < 4 or > 11.
Therefore, maintaining pH stability in the ideal range is very important for the success of Vannamei shrimp culture. This can be achieved by regularly monitoring water quality and using buffers or other pH adjustment treatments.

How to Maintain Optimal pH for Vannamei Shrimp?
Maintaining optimal pH stability in Vannamei shrimp culture requires regular monitoring and adjustment of water conditions. Here are some things you can do to maintain pH stability to keep it optimal:
1. Routine Monitoring
pH stability must be monitored regularly using a pH meter or pH indicator paper to ensure that conditions are in the optimal range for the growth of Vannamei shrimp.
2. pH adjustment
If the pH level is too low, it can be adjusted by adding a base such as sodium bicarbonate. Meanwhile, if the pH level is too high, it can be lowered by adding molasses.
3. Water Change
Regular water changes can also help maintain a stable pH level where waste products from shrimp farming that can change the pH concentration are also removed.
4. Avoid Overfeeding
Overfeeding can lead to a higher accumulation of waste products and decreased pH levels. Ensure you feed the right amount and immediately clean up the leftover feed that doesn’t run out.
