Mud fish This is a very popular fish in the market. Therefore, developing the model of raising mudfish is being directed by many households. Breeding mudfish has a high economic value, but farming and care techniques are not easy. Today, agri brings you a reference article about raising mudfish in ponds and even in the field, hoping that you will be successful in raising it.
Preparing ponds and tanks for mudfish
To raise mudfish, earthen ponds, cement tanks, tarpaulin tanks can all be raised.
People design tanks with an area of from 5 to 10m2 to facilitate the care, management and harvesting.
Choose a quality mudfish breed
In order to avoid much loss, people should buy a little larger size of scad, choose the same size, healthy, no scratches, bright colors and no disease.
The suitable stocking density of mudfish is 30 to 50 fish/m .2, size 2 to 3g each. Or you can drop 10 to 15 kg of seed per 100 m2 pond, seed size from 300 to 350 fish/kg.
The right time to stock mud scads so that they can grow well is from March to April after rice transplanting is complete, and if raised in cement tanks or tarpaulin tanks, they can be stocked all year round. Before stocking mudfish, conduct a preventive bath for them with salt water 3o/oo from 10 to 15 minutes, or can take a bath with Povidine dose of 5ml/m3 water.
After 3 to 4 months of rearing, at that time the commercial carp reaches the size of 25 to 40 fish/kg, then it can be trimmed or collected as a whole.
Management and care of mudfish
Raising fish in ponds and tanks
Make sure the water level is not more than 40cm, in the pond design ditches and holes from 50 to 60cm deep for fish to hide. Putting water hyacinth into ponds to create shelter for fish to avoid heat, cold and to clean the water environment is not a bad method.
When winter comes, it’s cold, people use rice straw to shelter fish, and at the same time pump water from 70 to 80cm high to intercrop with other fish such as carp, black carp to take advantage of excess food. .
Raising fish in the field
The mud bottom must be clean, the water level is from 20 to 40 cm, the bottom mud thickness is from 15 to 20 cm. In order to create natural food for the mud beetle, we will fertilize the manure and transplant the rice first. Dig a small ditch 1.2 to 1.5 m wide, 30 to 40 cm deep, running around the field to protect fish from the sun, hide when spraying pesticides and drain water when harvesting. The survival rate of mud loach in the field is 70 to 80%.
Mud cockroaches are relatively easy to raise, and their food is organic humus, which is extremely easy to find. When the mud slugs were young, they fed them with food with a protein content of over 30%, then gradually reduced the protein level. After 30 days of rearing, feed the fish twice a day (morning and evening) with 20 to 25% protein.
Disease prevention and treatment
Breeders of mudfish must have knowledge and experience in identifying diseases in fish. Once the disease is identified, it is not simply necessary to treat each fish, but also to treat the whole fish in the pond. Choosing the right medicine because sometimes, some drugs can accumulate in the mudfish’s body and affect human health.
Therefore, in the process of raising mudfish, “prevention is better than cure” is the maxim to remember and apply.
Comply with the technical process of raising mudfish. Feeding fish with adequate nutrients, especially when the fish are young, must be paid special attention. Feeding fish according to the “4 determination” method: Determining the amount of food, determining the feeding location, timing the feeding and determining the quality of the food.
Sardines can suffer from fungi, intestinal diseases, red spots and sores, etc. To prevent diseases, when feeding, add vitamin C and digestive enzymes to the food. Periodically feed 2 times / month, each time 3 to 5 days continuously. Remember to change the water periodically to avoid contamination.
When detecting a fungus, bathe the fish for 10 to 15 minutes with chemicals such as salt water 30/00 or KMnO4 at a dose of 20g/1m.3 water.
Feed the mudfish for 5-7 consecutive days with mixed antibiotic Doxycycline 0.2 – 0.3 g/1kg of feed + Oxytetracycline 2 – 4 g/kg of feed.
Raising mudfish is not easy, is it? However, if you know how to draw from experience and nurture your will, one day, this model will bring your family a good economic income. Happy successful people!
