Good characteristics of the pond for fish farming

Freshwater fish are raised in ponds. Water is taken from a lake, stream, well or another natural source is converted into a pond. Water passes through the pond once and then discharges, or can be partially altered to maintain one percent of the water contained in a system. Pond systems that produce high yields of fish only replace lost water through evaporation and filtration.
Water flow generally reduces the production of pond systems in the tropics. Fish farms vary from a few dozen square meters to several hectares. Small ponds are commonly used for spreading and small fish production, while large ponds are used for growth periods. Ponds over 10 hectares are difficult to handle and are not very popular in most producers.

The pools described here only serve as examples. The type of pond a farmer will make depends greatly on local resources, equipment, and conditions. Ponds are usually found on soft slopes. They are rectangular or square in shape, well-shaped dikes and do not collect water flowing from the surrounding basin.

It is important to have enough water available to fill all ponds within a reasonable period and to maintain the same level of pond water. You should also be able to drain the pond completely when you are going to harvest the fish. Background slopes need to be 2: 1 or 3: 1 (each height meter requires 2 or 3 meters horizontal spacing), which allows easy access to the pool and reduces the risk of erosion problems does.

To prevent fish theft, try to find a pond near your home. Another way to keep thieves away from their fish pond is to place bamboo poles or branches in the water, which makes fishing with nets and poles impossible. In addition to preventing theft, letters and branches provide extra natural food to the fish.

Important characteristics of the fish pond were presented.
Good characteristics of the pond for fish farming
Select a sloping land, taking advantage of existing landforms.
The ponds can dig in the ground. They may be partially above or below the original surface. The slope and the bottom must be well filled during construction to avoid erosion and sewage. The soil must contain at least 25% of soil. Stones, grasses, branches and other unwanted objects should be removed from the dikes.
The depth should be 0.5-1.0 m at the shallow end, slope 1.5-2.0 m at the end of the drain.
The best shape for pools is rectangular or square.
Side slope
Make pools with 2: 1 or 3: 1 slope on each side.
Gate valves, deflector panels or vertical indicator pipes must be provided. The drain should not take more than 3 days.
Flow lines
Entrance lines must be filled to fill each pond in 3 days. If surface water is used, incoming water must be filtered to remove unwanted plants or animals.
The total amount of water
In a few weeks, there should be enough water to fill all the ponds on the farm and fill them in the growing season. 
The dikes should be wide enough to allow cutting. Deck roads want to be made of gravel. It should be weed anyway. 
Carefully locate the ponds to benefit from mixing water with air. In areas where the wind causes wave erosion, place the long sides of the pond at right angles to the wind. Use a hedge or tree wind protection where necessary.
