EM4 Becomes the Mainstay of Tilapia Cultivation

EM4 Becomes the Mainstay of Tilapia Cultivation

West Nusa Tenggara (NTB) has considerable natural and fishery and natural resource potential, especially in terms of freshwater fish farming. Among these are carp, tilapia, gurami, catfish, pomfret and tawes. But the current trend is tilapia. Indeed gouramy is still a favourite, but due to the length of cultivation which reaches more than one year and the price of the more expensive per kilogram causing velocity of money is slower, tilapia only requires four months to harvest and the price is very affordable resulting many people switch to consuming tilapia.

Travelling to the city of Mataram, Lombok, would not be ‘afdol’ if you did not taste the Taliwang chicken. But apparently in many outlets or restaurants Taliwang chicken, grilled tilapia fish is also a culinary mainstay of Lombok. It’s delicious to eat but of course with rice that is still hot and fresh, with water spinach and Lombok typical chilli sauce. Lombok, which is the best tourist destination in Indonesia, is of course also the target of Lombok’s culinary hunters.

Well, this is where freshwater fisheries reap blessings. Many of these fresh fish farming groups spread their wings. Expanding the marketing network to outside islands such as Bali to meet the needs of freshwater fish. “We order a lot of freshwater fish, especially tilapia, gurame, pomfret from the island, especially from hotels around Kuta and Nusa Dua, but unfortunately we have not been able to fulfil this request,” said Sulhan (45) an aquaculture fish farmer that has been almost 30 years in the business.

Location: West Nusa Tenggara


Indeed, for Sulhan, the business he engaged in, brings blessings to his family and also the freshwater fish farming farmer groups that he pioneered. A business that was pioneered on the highway Praya Mantang Praya Central Lombok. Every day is able to meet the needs of the community for freshwater fish reaching 5 tons per day. Not to mention the demand for several hotels in Bali. “Through a joint effort of about 30 groups of tilapia fish farmers, we meet the needs of the community for the provision of tilapia in Lombok,” he said. It’s no exaggeration, Sulhan is a breeder who has been in this freshwater business for a long time. Starting from pomfret, catfish, carp, indigo and others. In addition to the enlargement of fish consumption, Sulhan is also in the nursery business. ” I have been in the business of this freshwater fish, and the most effective way to maintain fish health so that production continues to grow is to use EM4 technology. We have tried many products, but only EM4 is the most superior and the most affordable (so cheap) so it gives a very good profit, ” he said. With 25 employees at the moment, Sulhan continues to exist in the tilapia business and becomes the largest freshwater fish supplier in Lombok with a turnover of tens of millions of rupiah. ” Thank God, the business continues to run, fish production continues to increase very rarely affected by diseases that are harmful to fish. And it can be maintained because of the healthy pond conditions free from disease due to EM4 treatment on cultivated land. As is well known, EM4 in fisheries is indeed very effective in keeping fish healthy. Because the function of EM4 in fisheries is to increase bacterial decomposition of organic matter, suppress the growth of pathogenic bacteria, stimulate digestive enzymes and improve water quality in cultivated land. That EM4 in fisheries functions to maintain the body of the fish and increase fish growth and increase immunostimulatory or endurance of the fish so that it reduces the use of antibiotics. ‘ Not only that EM4 also ferment the remainder of the feed, dirt, at the bottom of the pond and increase dissolved oxygen (DO) and water to be clean so that no water replacement is needed repeatedly. As well as describing the ammonia, methane and hydrogen sulfide gases and environmentally friendly.


The use of EM4 in this fishery can be applied either during processing of the basin or during maintenance. In the Basement of Soil Basin, so once the soil is dried and plowed then is soaked in 20 cm of water then watered with EM4 of 6 liters per ha, leave it for 4 – 7 days and let it dry for 4 days. The soil is lime with estimated 300 kg / ha and cultivated with 250kg / ha Bokashi EM. Drain the water at a height of 20 cm, then wash with 6 liters of EM4 solution, and let it sit for 1 week. Add water up to 60 – 80 cm at the same time and rinse EM4 at 6-8 litres/ha, then allow for 1 week until the seed is dispersed. During maintenance, after 1 month of age, apply EM4 of 1 – 3 ppm/week/ha or at the time of water replacement according to the water condition. It should be explained, 1 ppm = 1: 1 000,000) when the height of the water is 60 cm, then EM4 of 6 litres is required, while 80 cm of water is required, 8 litres/ha). The 60-75 cm deep-water pool is ready for a fish hatchling. Stocking densely packed ponds for tilapia as much as 15-30 fish / m2. Assuming, the hatchling size is 10-20 grams/head and will be harvested with a size of 300 grams/head. Before the hatchling is put into the pond, it should pass the adaptation stage first. The point is that fish hatchling is used to pond conditions, so the risk of hatchling death can be reduced. The trick, enter the container containing the hatchling of tilapia into pond water. Leave for several hours. Then tilt or open the container. Let the fish come out and loose by itself. After all the preparations are done and the hatchling has been put into the pond, the next step is to take care of the fish until the age of harvest. The three most important things in maintaining tilapia aquaculture are water management, feeding and pest control. But with EM4 administration, fish will be protected from disease. Now, to maintain water quality and maintain fish health, just use EM4 Fisheries so that the harvest is optimal. *
