Freshwater fish breeding such as Red Tilapia, Catfish and Climbing Perch can be carried out in cement or concrete tanks with a size of 500 m2 (50 m x10 m). It is estimated that the construction cost of the cement tank is between RM 8,000 – RM 10,000 per unit complete with inlet and outlet. It is recommended that the stocking of fry for the cement tank system is 15 fry/m2. The method of feeding and water management is the same as for other systems and priority is given to formula feed. To breed in cement tanks, it is recommended to use additional ventilation equipment, such as paddle wheel or blower to increase the survival rate of fish.
The Department of Fisheries Malaysia also offers scheduled courses and training attachment for the aquaculture sector but is limited to ground pond systems, cement tanks and cages only. To apply for a course, it can be done online or  via the District Fisheries Office. Breeders can get more information about the tank from the nearest State Fisheries Office. The address for VAT can be obtained from the website of the Department of Fisheries Malaysia in the Department Directory section.
