There are several types of fish that can be kept in fresh water. There is also the betutu fish. Perhaps what we hear most often is ayam betutu, which is chicken processed with Balinese spices.

However, it turns out that there is also a type of Betutu fish and it turns out that this is not processed fish served with Balinese spices. This Betutu fish is not well known in the market.

Therefore, it is natural that this type of fish is not well known in the community. This type of fish is actually all over the world too, just under a different name. Some other names are lazy snakehead fish, as they are called in the business world. Bakukut, which is the name of the people of Kalimantan. Sun Hok is the name given by the Chinese. While its name in the international world is Marbled Goby or Sand Goby.

Of the many names, it turns out to have a very high economic potential. Because it turns out that the processing from this type of fish is not only for consumption but also becomes postoperative medicine. Just as neighboring countries like Singapore, Malaysia, and even Japan have done, the skin of this betutu fish is a medicinal oil for patients after undergoing surgery.

Meanwhile, at the national level, betutu fish is a processed food for consumption. Processed betutu fish menus have entered big cities in the archipelago such as Jakarta, Yogyakarta, Semarang, Bandung, Medan, Surabaya and even Palembang. And the price of a processed betutu fish is no joke either. The betutu fish menu offered at this five-star hotel has a price range of Rp. 250,000 to Rp. 300,000 for betutu fish from 0.8 kg to 1 kg.

This Betutu fish is known as lazy fish or lazy cork. This is because these fish do not move much until human hands touch their body parts. There is something interesting about this culture of betutu fish. Maybe not as easy as farming other freshwater fish, such as organic catfish farming in canvas ponds, cork fish farming in canvas ponds, carp farming in concrete ponds, culture of carp in full-wall ponds. Here are things you need to know to undergo betutu fish farming:

1. Choose a good father Betutu

The most important initial stage in breeding is to have a good candidate for broodstock. Even in pomfret farming and cursed fish farming, it is still necessary to choose good broodstock. Having a good stock of spawners can be obtained from a sorting group of betutu fish. In general, there are betutu fish that are caught directly from the wild and some are farmed as well.

2. Know the characteristics of a good father

Because the breeders of this betutu fish can be straight from the wild, it is important that you know what the characteristics of good quality betutu breeders are. For breeders that are female, there are more black spots on fewer parts of the body. So this mother has a dark skin color.

Meanwhile, male breeders have fewer black spots on their bodies and their skin color is lighter. In general, male and female betutu weigh around 175 grams. It’s just that the body of reproductive males is slimmer. Another thing that is important for betutu fish breeders is to have a healthy body.

3. Accelerate the Reproductive Process

It is important to do this if you do not directly purchase the seeds that have been provided for distribution. Breeders of betutu fish that are ready to spawn are breeders that are in their productive period. To help the mating process of the reproductive organs of the spawners faster, you can put the spawners in special care for spawners. In this care of the brood, the possible reproducers will receive a good feeding. These foods can be natural or artificial foods. The most important thing is that this food has a high protein content.

4. Pay attention to the cleanliness of the pool

Although this pond is only temporary to speed up the breeding process, it still needs to be considered. Ponds for betutu broodstock can be made in ponds made of kakaban or cement ponds. The thing to keep in mind is the cleanliness of the pool and the air supply in it.

5. Spawning Pond Setup

If the spawning pond you have has a pool area of ​​200 square meters. Therefore, the pond can accommodate up to 35 pairs of betutu breeders. However, if the potential spawners you want to prepare are only for a few queues, then you can prepare an 8 meter square pond that can accommodate up to 4 pairs of potential spawners. To help stimulate the fish, the water must be changed continuously.

6. Betutu fish spawning

Before spawning, potential spawners will usually adapt first. There are at least 5 stages in the spawning process of potential betutu spawners. First, potential breeders will begin to mark their territory. Then the next stage is to make a nest before the marriage occurs. In the next stage, when the marriage has occurred, there will be eggs in the nest and the mother will maintain the existence of these eggs.

7. Remove the eggs from the nest

After the female has laid the nests that have been made, it is time to erect the nest and move it to the hatchery that has been previously prepared. To stimulate the hatching of the eggs immediately, she can continuously spray the pool water. To prevent the appearance of mold, you can also use methylene blue. In 3 days later, the eggs can begin to hatch.

8. Prepare advanced feed for larvae

When betutu fish eggs begin to hatch, the fish larvae will eat from the yolk food reserves in the nest. After that, you can prepare food in the form of food for softened pellets. When these larvae have grown, it is time to transfer them to the rearing pond.

9. Growing Betutu Fish in the Aquarium

Breeding pond for betutu fish can also be done in the aquarium. Although it can be done in an aquarium, it is just that the development and growth of betutu fish in this aquarium becomes less flexible. The lack of aquarium size is also one of the worrying factors for betutu fish. This rectangular corner of the aquarium can injure the betutu fish’s mouth when it ambushes its food. So, if there is still land available for betutu fish farming ponds, it is better if this culture is carried out in soil ponds as in its natural habitat.

10. Culture of Betutu fish in earthen ponds

Not only betutu fish that can be farmed in earthen ponds, various other fish such as pomfret can also be farmed in earthen ponds. Fish density in this cement pond can be as high as 16 fish per square foot. Use aquatic plants and black plastic for soft lighting. The presence of plants and black plastic is to protect the fish from direct sunlight.

You can also make a hideout out of shingles or PVC pipe. The depth of the water is only 40-50 cm enough for the betutu fish to chase the young fish that will later become their food. You must also prepare a dissolved oxygen content that has a dose of DO > 5 mg/l.

11. Food

There are two types of betutu fish food, namely natural food and pellet food. Due to the composition of the natural feed itself in the form of guppies (ketol) or river prawns. Meanwhile, the pellet feed itself should have a protein content of 36%. The more fish the pellet feed is given, the better it is.

12. Feeding time

This betutu fish feeding time does not have a specific time reference point. Betutu fish are less responsive to dead food, but are still fresh. This betutu prefers live food, but will start attacking food when the food is not aggressive.

13. Betutu Fish Breeding

The keeping of this betutu fish can be combined with the farming of other fish such as tilapia and tilapia. However, those kept in a pond are breeding fish. This is done in an effort to provide live food for tilapia and tilapia betutu fish that live in the same pond.

14. Keep the pool clean

Although the habitat of this betutu fish is usually in ponds that have brackish water, you need to make sure that the condition of the betutu fish pond is not dirty and muddy like a catfish pond. For cleaning, the ground pool can be drained regularly within 10-15 days. For canvas ponds and cement ponds, it can be drained no later than 2 weeks or once a month. This is done to avoid moss and scale that can appear on the walls and could have the potential to kill fish.

15. How to empty the pool

When draining the pool, it is not necessary to drain all the water at once and then clean it. You just throw away 30% – 50% of the pool water, then you can continue brushing the pool walls without hurting the fish in the pool. The equipment that can be used to brush the walls of the pool can be through a bath brush.

16. Treatment of sick fish

This betutu fish can also get sick when farmed. The types of diseases that usually attack you are bacteria or fungi. And the appearance of bacteria or fungi is provoked by dirty water. To treat it, you can use a saline solution at a rate of 200 grams per liter and do it for 10 minutes. This is repeated until the fish are completely free of bacteria and fungi.

17. Harvest Betutu Fish

This betutu fish can be harvested when it enters the age of 8 to 12 months and has a minimum weight of 4 ounces. This harvest of betutu fish can be done during the day. Prepare a shelter such as a plastic tub. The water in the pond depreciates, so you can take the betutu fish and put it in the tub that has been provided for you earlier. The betutu fish that have been harvested are then adjusted and graded according to their respective sizes.

Therefore, an explanation on how to farm betutu fish that is good and correct for beginners in order to produce quality betutu fish breeding.
