Water quality parameters such as pH, water hardness, temperature, dissolved oxygen and brightness are things that need to be considered in tilapia aquaculture. In order for the purpose of tilapia aquaculture to be achieved, the water quality parameters mentioned above need to be maintained and maintained to remain in optimal numbers.
In tilapia farming activities in ponds monitoring pond water temperature is an important activity that needs to be considered. Fish pond water temperature is very important to maintain the health of fish and the surrounding environment. Water temperature plays a role in helping fish metabolism. Tilapia growth will be faster if the pond water temperature ranges from 25°C to 30°C. If the pond water temperature is too cold, which is below 25 ° C, the growth of tilapia will be inhibited because if the pond water temperature is too cold it will reduce the metabolic rate of the fish and will inhibit the fish's appetite so that its growth will be inhibited.

To find out how much the pond water temperature is we need to measure it. How to measure pond water temperature is by using a water thermometer. There are several types of water thermometers that can be used, such as digital thermometers, dip thermometers, and infrared thermometers. You can choose the type of water thermometer that suits your needs.
To measure the pool water temperature, the most suitable time is during the day. According to research, the pattern of water temperature changes in aquaculture ponds shows a high pattern during the day, low in the morning and moderate in the afternoon. If you want to measure pond water temperature at other times, make sure to avoid times that are too early in the morning or too late at night.
Pond water temperature can be affected by many factors such as solar radiation, air temperature, weather and climate. Therefore, it is advisable to measure the pool water temperature at a time that is relatively stable and less affected by these factors.
Changes in temperature that are too fluctuating will stress the fish. Stressed fish will be susceptible to disease attacks. How to maintain a stable fish pond water temperature are,
1. If the pond used for tilapia farming is a tarpaulin pond, then make the tarpaulin pond half buried in the ground. You can make a half-submerged tarpaulin pond in the ground and cover the bottom soil with 5 cm thick rice husks. The soil and rice husk can store and absorb heat so that the pond water temperature is more stable, especially at night.
2. Keeping the pond water temperature stable can also be done by maintaining the water quality of the fish pond. Keeping the pond clean and monitoring the water quality regularly is very important to maintain the stability of the pond water temperature. Make sure the fish farming pond gets enough sunlight and use a water thermometer to measure the temperature accurately.
