One of the water chemistry parameters that you as a farmer must pay attention to is value Optimal shrimp TOM in ponds. TOM or excess organic matter in aquaculture waters is toxic to shrimp and can cause stress symptoms, reduce appetite, trigger disease growth, and even trigger mass death.
There are certain numbers used to describe the number of TOM in shrimp ponds. Let's read further to find out the good TOM values for shrimp ponds and how to control TOM in shrimp ponds!
Total Organic Matter (TOM) is an illustration of the amount of dissolved, suspended, and colloidal organic matter in shrimp pond waters. Good organic matter content is 20 ppm, while the maximum limit for organic matter content is 80 ppm (indicating poor water quality).
Physically, the high TOM value can be seen from the condition of the waters. If it is cloudy and smells bad, it means bad water conditions. And vice versa, if the water conditions are relatively clear and odorless, it means that the water conditions are good.
The high and low TOM values in a water are caused by an increase in the accumulation of organic matter that has accumulated at the bottom of pond waters. This worsens the water quality of shrimp ponds. The following things affect the TOM value in a shrimp pond waters:
Some efforts that can be made to control the TOM value are as follows:
Total organic matter content or Total Organic Matter (TOM) can be a benchmark in controlling organic matter in pond waters. TOM values can be used to evaluate shrimp cultivation harvest plans so that pond quality is maintained even better.
