Profitable fish farming
Sandy or mountainous land is not suitable for fish farms, but it can be made useable by making some changes, such as by plastering a plastic lining or by placing a thick layer of clay on the floor and edges of the pond. But it will require extra investment and extra care.
If the ponds are built on unmanaged and slightly deeper soils, the cost will be reduced and thus wasteful land can also be used. Ponds can also be made on seawater and on land.
Ponds are made up of several types such as:
(1) surface completely below ground,
(2) half-level below ground and a half above and
(3) level completely above ground.
Each of these types is related to water supply and emissions. The first type is suitable for canal areas where you fill the pond with full canal water. A pump will be needed to drain the water from such a pool. In addition to canal water, tube well water will also be used to fill the second type of pond. Similarly, when the water is discharged, half the water itself will be discharged while the rest will have to use the pump. While the last type of ponds are suitable for areas where no canal water is available and your sole dependence on the fill of the tube well for filling the pond. No pump is usually required to drain the water from such a pool, thus saving the cost of pumping a second time.
The height of the ponds or its slaves should be so high that the water can stand 5 to 7 feet.
The size of the pond should be such that water quality and fish food and health should be taken care of easily. The pond can be built from a few feet to several acres, but a quarter to half an acre (2 to 4 kanals) is a suitable starting size. Creating a pond larger than 2 acres (16 kanal) should be avoided because the larger the pond, the more difficult it is to maintain and control.
Proper drainage should be made on the water entry and drainage routes in the pond. If the canal water is to be used in the pond then at least 60 holes per inch net should be laid at the entrance and if the tube well water is to be used then it should not be neat, however. Fine-netting does not allow fish eggs and babies to enter the pond from canals and agricultural lands, so your domesticated fish will continue to grow better.
The baby should be put in the pool as much as you can for dung, fertilizer, or food. Under normal circumstances it is not advisable to put less than one thousand acres and more than 3000 children and the costs incurred on your pool will not be balanced.
The baby should be pure, healthy and standard and should be purchased with a good fish hatchery. If the baby is not pure and includes wild fish species, they will cause nutritional competition with your breeder seed and thus will not lead to good growth of your domesticated fish.
The baby should be planted in February or March so that the fish can grow better in the warmer months and your fish will be ready before the cold begins. If you can't get your form started so quickly for some reason, put seeds as soon as possible so you can take advantage of the summer season.
One of the principles of successful fish farming is to have a puppy nursery along with your pond to provide the necessary fish seed for your pond. The nursery pool should be up to 10% of the total area.
Different types of fish can be fed separately or even together, but it is better to breed them together so that the natural diet of fish produced in the pond can be fully utilized.
Dung or agricultural fertilizers should be used to make fish ponds fertile, thus higher yields can be achieved at lower costs, but dung should not be allowed to accumulate in large quantities in a single pond.
The watercolor should be green. This is also a good sign if ever browned, but the fertilizer should be added to the pond as soon as possible so that its green color returns.
The water in the pond should be checked regularly so that its quality is maintained and oxygen is not lost, no harmful gases and substances are added. The minimum amount of oxygen in the pond should be 5 ppm (mg per liter) in the morning.
If your pond starts to exceed pH 9.5 at sunset, the fertilizer should be discontinued. When the pH drops below 9.0, start the fertilizer again but in smaller quantities than before.
If livestock farms or poultry farms are already in place, additional income can be obtained by feeding fish at a lower cost than planting a fish farm, as dung and poultry bats are a great source of natural food for fish.
Extracting weeds and shrubs from fish ponds improves fish growth and increases yield. Plants cause a decrease in the natural diet of fish.
It is best to prevent the plants in the pond before they are born. An easy solution to this is to use agricultural fertilizers in the pond at the end of winter, thus the natural diet of fish, which consists of highly microscopic plants and animals, is produced in large quantities in pond water and in green. Make the most of it and the big plants do not take root.
If there are already aquatic plants in your pond and it is difficult to remove them, also add grass carp along with other fish.
If possible, empty the pool and teach it every year until it has a crack. Thus, the soil will be oxidized and the phosphorus and other components contained in it will be reused and the harmful germs will be eliminated.
Some other things to keep in mind about fish ponds are:
There is no salt in the pond, meaning the water is suitable for human or livestock drinking.Hazardous gases such as ammonia and hydrogen sulfide can be stored in the pool if food and dung are not allowed to accumulate on the pond floor. Ammonia is usually present in small quantities in the pond, but if water quality deteriorates or pH is high, it becomes extremely harmful to fish.
Fish theft is also an important issue, so appropriate steps should be taken to prevent it.
