How to build a pond to raise fish?

1. Location selection: Choose a place with sufficient water source, unpolluted water quality, convenient transportation and power supply to build a pond. \x0d\x0a2. Water source and water quality: A good water source is convenient for frequent addition of new water to prevent fish from dying due to water quality deterioration and lack of oxygen; it is also beneficial to the growth of plankton and improve the living conditions of fish. The best water source for the pond is river water and reservoir water. \x0d\x0a3. Moderate area: 3-5 mu is suitable for fry and fingerling ponds, and 8-10 mu is suitable for adult fish ponds. A large area is suitable for the biological requirements of fish and the range of fish activities is wide. The water surface is wide and is greatly affected by wind, which can automatically add oxygen to the pond. There is a saying in fishing proverbs that "wide water raises big fish". \x0d\x0a4. Moderate water depth: The water depth of the pond is 1-1.5 meters for fry ponds, 1.5-2 meters for fingerling ponds, and 2-3 meters for adult fish ponds. With such a water depth, the water quality is not easy to change drastically, which can increase the fish carrying capacity of the water body and improve production and efficiency. \x0d\x0a5. Good soil quality: The soil of the fish pond must have good water retention. Generally, loam is the best, followed by clay, and sand is the worst. \x0d\x0a6. Pond design: The shape of the pond should be a rectangle that is long from east to west and wide from north to south, with a length-to-width ratio of 5:3 being the best. With such a pond shape, the embankment has little shade and long sunshine, which is conducive to the photosynthesis of phytoplankton, as well as feeding management and net pulling operations. The bottom of the pond is in the shape of a turtle's back, and the entire bottom of the pond is inclined toward the outlet, which is conducive to drainage and fishing. The area around the pond should be open, and it is best to plant forage grass on the embankment. It is not advisable to plant tall trees to avoid blocking sunlight and wind. \x0d\x0a\x0d\x0aExtended information: \x0d\x0aA fish pond refers to a place for fishing or fish farming, especially the internal compartments of a fish pond or the enclosure net that encircles the fish. Generally, an ideal pond requires a large area, deep water, sufficient light, unobstructed water source, fertile water quality, and convenient transportation, so as to facilitate the growth of fish and increase production, and facilitate production management. \x0d\x0aIt should meet the following conditions: \x0d\x0a1. Area and water depth. The size and depth of the pond are closely related to the level of fish production. Production practice has proved that the area of ​​a mature fish pond is preferably 4-10 mu, and the water depth is preferably 2-3 meters. The area of ​​a fish pond can be less than 5 mu, and the water depth is about 1.5 meters. \x0d\x0a2. Soil quality and bottom quality. Fish ponds are mostly built by digging soil, and the soil quality has a great impact on water quality. Black soil is the best soil for ponds, followed by clay, and sandy soil is the worst. \x0d\x0aAfter a period of fish farming in the pond, a thick layer of silt gradually forms at the bottom of the pond. This is the result of the continuous deposition of residual feed, fertilizer, fish feces and dead organisms, mixed with the mud and sand at the bottom of the pond. There is a certain amount of silt in the pond, and the pond water is easy to become fertile, which is conducive to fish farming and high yield. However, too much silt will deteriorate the water quality, affect the growth of fish, and even cause the death of fish. Therefore, excessive silt must be removed in time to maintain good water quality. \x0d\x0a3. Water source and water quality. Good water quality requires sufficient dissolved oxygen, moderate acidity and alkalinity (PH value 7-8.5), good water temperature (preferably 25-30℃), rich nutrients, rich water quality (water color is mung bean color, yellow-green, yellow-brown and light soy sauce color, transparency is 25-30cm), and no toxic substances. \x0d\x0a4. The shape and direction of the pond. The shape of the pond is preferably rectangular. The ratio of length to width is 2-3:1, and the width is 30-50 meters long, which is convenient for management and fishing. The direction of the pond should be east-west, which is conducive to extending the sunshine time, which is good for plankton in the water and increasing dissolved oxygen. There should be no high mountains or tall trees around the pond to block the light and wind.

Construction of a new type of fish pond: Can a 3 square meter fish pond be used to raise edible fish?

Construction scale: The minimum scale is 300 mu, and the fish ponds are required to be neat and continuous. The recommended area of ​​one pond is 300-1000 mu. Earthwork supporting projects: 20% of the area is for fish ponds and 50-100% of the area is for feed bases. When the water depth of the fish pond is 2.5-3m, 800-1000 cubic meters of earthwork needs to be excavated. Fish pond design standards: The rectangular fish pond area is preferably 15-20 mu, with a water depth of 2.5-3m and an east-west orientation.

1. Construction of new fish ponds

1. Construction scale

The minimum scale is 300 mu and the fish ponds must be neat and connected. Based on the current management level, it is recommended that one pond be 300-1000 mu. An area too large is difficult to manage.

2. Supporting earthwork for transporting and burying celery

(1) The main body is intensive fish ponds, with a 20% fish pond and a 50-100% feed base (at least not less than 40%).

(2) For each fish pond with a water depth of 2.5-3m, 800-1000 cubic meters of earth needs to be excavated. If the soil is sandy loam, more is needed.

3. Fish pond design standards

(1) Fish pond

① Area: The area of ​​a pond should be 15-20 mu, and the water depth should be 2.5-3m.

② Shape: The fish pond is rectangular in shape, with a long side of 200m and a short side of 20m, that is, 15 mu per pond.

③Embankment width: The width of the long side embankment should be 15-20m, and the width of the short side embankment should be 4-6m.

④ The slope of the embankment: It should be determined according to the soil type. If it is loam, the slope on the side close to the drainage ditch is 1:2, and the slope on the side close to the fish pond is 1:2.5 or 1:3; if it is sandy loam or sandy soil, the slope on the side close to the drainage ditch is 1:2.5 or 11:3, the slope on the side close to the fish pond is 1:3 or 1:4, and the outer side of the embankment is 1:5.

(2) Fish species matching pond

① Area: The area of ​​one well should be 2-4 mu, and the water depth should be 1.5-2m.

②Shape: The best shape is a rectangle, with the ratio of the long side to the short side being 1:2.5 or 1:3, and the direction being east-west.

③Embankment width: The width of the long side and the short side can be the same, preferably 2-4m.

④Embankment slope: Because the water area of ​​the fish pond is small and is less affected by wind and waves, a slope of 1:2 can be sufficient.

4. Feed base supporting

Taking the case of a short dike with a width of 5m, for example, it is a fish pond (15 mu) that is 200m long and 50m wide. When the long side is 10m, the feed base area accounts for 25%; when the long side is 12m, the feed base area accounts for 29%; when the long side is 15m, the feed base area accounts for 35%; when the long side is 18m, the feed base area accounts for 38%; when the long side is 20m, the feed base area accounts for 40%.

2. Can edible fish be raised in a 3 square meter fish pond?

1. Can you raise fish in a 3 square meter fish pond?

Generally, edible fish can be raised in a 3-square-meter fish pond, but if the fish pond is too small, insufficient oxygen supply may lead to death. It is recommended to raise small fish. If you want to raise large fish, you can raise them in a larger fish pond.

2. Things to note when raising fish at home

(1) When using tap water to raise fish, it is necessary to remove liquid chlorine from the water and change the water in small amounts every day. You can use a small water pipe to suck out fish excrement and bait from the bottom and then replenish the sucked-out water.

(2) Live fish worms can be used to maintain water quality, but the amount should not be too much. If the fish cannot eat them all in time, the fish worms will die and damage the water quality. Note: Dried fish worms cannot retain water.

(3) Change the water once a month or every 2-3 weeks, clean the fish tank and rearrange it. When cleaning the sink, scrape off the moss, scrub the bottom stone thoroughly, and dry the water 2 days in advance.

(4) Observe the growth of fish regularly. If any disease is found, isolate and treat it in time to avoid affecting other healthy fish.
