Muddy, tender meat with high nutritional value, these fish are popular export species, mainly shipped to Japan and South Korea. Their unique texture and flavor make them highly sought after in Asian markets.
First, site selection and construction of aquaculture ponds are crucial. Farms should be located near a reliable water source, with clean, fresh water that is free from pollution and easy to manage for irrigation and drainage. The soil should be neutral or slightly acidic, preferably clay loam or sandy loam, which helps retain moisture and supports healthy growth. The area should receive plenty of sunlight and have convenient access for transportation and electricity supply. The typical size of each pond ranges from 100 to 250 square meters.
Around the pond, it's essential to build a strong escape-proof wall. Brick and cement are commonly used to construct a 40-centimeter-high barrier. Alternatively, plastic boards or wire mesh can also be effective. Some farmers use compacted triaxial soil for cost-effective protection. Another option is to install window screens along the edge of the pond, buried deep into the ground with the top part 20 centimeters above the water level. This ensures that the fish cannot jump out.
In the center of the pond, a connected gutter is installed, positioned 30 to 40 centimeters below the pool bottom. The overall depth of the pond is about 0.8 to 1 meter, with a maintained water depth of 30 to 50 centimeters. An overflow port is placed at the normal water level, while the water inlet is 20 centimeters above the surface. All inlets, outlets, and overflow ports are covered with fine wire mesh to prevent fish from escaping. A drain pipe is installed at the bottom of the ditch and sealed with cement to ensure proper water flow and control.
Second, pond water disinfection and fertilization are essential steps before stocking. Before filling the pond with water, a layer of 10 centimeters of advanced water is left. Then, 75 kilograms of lime per 667 square meters (about one acre) is mixed into a slurry and poured into the pond for disinfection. After the water settles, sufficient base fertilizer is added to enrich the water body. The water clarity should be maintained at around 15 centimeters to support optimal conditions for fish growth and health.
A fence railing is a structure used to protect and define private or public spaces. It is usually made of different metal materials and is installed around the perimeter of a building, site or area to prevent unauthorized entry or to provide additional security. Fence railings are designed with aesthetics, functionality, and cost in mind.
1. Security & Privacy: Fences prevent outsiders from entering, protecting the safety of occupants or users, while providing a certain amount of privacy to the interior space.
2. Aesthetic decoration: With different designs, materials, and color options, fence railings can become a part of the landscape and enhance the overall aesthetic appeal.
3. Boundary Definition: Clearly define the boundaries of a specific area to help people understand what is accessible and what is restricted.
4. Wind and rain protection: In some areas, fence guardrails can also play a role in wind, rain protection, and protect the building from bad weather.
Material Type:
- Metals: such as wrought iron, aluminum alloy, etc., with strong durability and relatively low maintenance costs.
Design & Installation:
- Height: Depending on the purpose of use and regulatory requirements, the height of the fence guardrail may vary.
- Spacing: The spacing between the vertical rods is less than 110mm.
- Material strength: Ensure that the material chosen can withstand the expected environmental conditions and potential impact forces.
- Installation: Consider the ground foundation, soil conditions and terrain characteristics to ensure firm and stable.
