I suggest you build a semi-basement to raise fish. Your own buildings are all red brick and red floor. They don't have that much tolerance. Unless you use steel bars to make cement, the cost is too high.

It is necessary to build three ponds, one with a maximum size of 1 50m2, one with a size of 40m2 for water storage and one with a size of1to 2m2 for filtration. If it is waterproof, use pvc board for the roof. Don't go up when it is damp-proof. Just put tiles on the walls and ponds. There are at least five advantages of raising flat-topped goldfish in concrete houses: 1. Because the water storage is shallow, it is suitable for general roofs. 2. It can be used for ornamental breeding and commercial development, and it is a good way to get rich quickly with less investment. Planting flowers, fruits and vegetables to shade fish ponds can beautify the environment, purify the air and cultivate people's sentiments. 4. It can prevent heatstroke and cool down, playing the role of being warm in winter and cool in summer. This is easier to manage than land cultivation. The culture technique is as follows:

1. Generally, each pond is built in 5-20 square meters, with a water storage depth of 30 cm and a wall height of 40-50 cm. The ponds are connected in rows, which is convenient for operation, water intake and drainage, and independent of each other, laying a good foundation for disease prevention and healthy breeding. NbspW, what is it? The water storage capacity of the reservoir (solar pond) is 65438+ 0/2 of the water demand of a single fish pond. The bottom (i.e. top) surface of the pool should be repainted with 200 cement mortar with a thickness of 3-5cm to prevent leakage. Install the inlet and outlet pipes.

Second, the purpose of setting up a shade shed is to block the direct sunlight in summer, avoid the water temperature in the fish pond from rising too high, and create a good growth environment for goldfish. Shading shed should be higher than the pool wall 1-2 meters, and it is required to have certain weather resistance. Grape, towel gourd, pumpkin and other cash crops with vines or flowers on the shed play a role in shading.

Three, five days before stocking, according to 20 grams of bleach per cubic meter of water, the whole pool is evenly sprayed for disinfection. When the goldfish enters the pool, it is washed and sterilized with 3% salt solution. Generally, the stocking quantity of Tianzhu, Gaotou and Wangtianyan per square meter. It is 2 cm long, 100-200, 5 cm long, 50- 100, 10-20.

4. goldfish are omnivorous fish, feeding on plant and animal feed. Productive farming mainly relies on artificial compound feed. This paper introduces the preparation of several artificial compound baits:

(1) Grinding rice bran and bran, steaming, mixing with shrimp powder, cooling, pulverizing into particles, and drying in the sun;

(2) 40% fish meal and 60% wheat bran are mixed, then yeast powder with the weight of 0.65438+/-0% is added, mixed with 1%-2% gum, steamed and dried;

(3) Wheat flour, bean cake, fish powder and shrimp powder are mixed and ground into paste, and then dried with alum and kneaded into particles (floatability).

Feed it once every morning and evening. The amount of bait should be flexibly grasped according to the "three looks": depending on the feeding situation. If the bait is eaten quickly, it should be increased appropriately, otherwise it should be reduced; Second, look at the weather and shoot more on sunny days, and shoot less or not on hot and rainy days; Third, look at the activity of fish. The fish body is strong, the water temperature is suitable for more investment, less investment or no investment when the disease occurs, and no investment when the head floats or has floated.

The purpose of changing water is to keep the water clean and have enough dissolved oxygen. Visually, the color of water is yellow, powder gray or dark green, which has a bad smell and turns sour. When the fish float during the day, it is necessary to change the water, otherwise the fish will be born? Nbsp(7) why not? What is this? Is there the word pro-Yue here? What's the matter with you? /4- 1/3, which can be sprayed directly; If the fish pond is completely dried to change water and the fish is put back immediately, then the water that has been exposed to the sun for more than one day in the reservoir should be added to avoid the excessive chlorine content in tap water and the excessive temperature difference between water and water. When changing water, it is not advisable to change too much at a time, and it is not advisable to change it all at once. The temperature difference should not be too large to avoid rushing down. It is ideal to keep the water color of fish ponds light green.

Six, disease prevention According to the author's experience, the most common disease of pond goldfish is water mold? Nbsp[6] meng? ⑹? 槴槴槴槴槴槴槴槴槴槴槴槴槴槴槴槴槴槴槴. (1) Clean the pond and disinfect it before stocking;

(2) Fish disinfection during stocking;

(3) Antibacterials are often added to the bait for prevention;

(4) Keep the pool water light green;

(5) Newly purchased goldfish should be kept separately, and cannot be mixed into fish ponds casually;

(6) Strengthen the management of vines such as grapes to make them flourish and enhance the shading effect;

(7) If fish diseases are found, the right medicine should be taken to prevent them in time.

Seven, wintering winter, goldfish can be properly combined with the pool, blocking the overflow, adding the pool water to the deepest, wintering in the south; In the north, it is necessary to build a plastic shed to keep warm.
