How to use the roof culture goldfish
First, the construction of fish pond fish pond is generally 5 square meters to 20 square meters, water depth 30 cm, pool wall height 40 cm to 50 cm. The pools are connected in rows and are independent, which is conducive to operation and is also conducive to disease prevention. In addition, it is advisable to make a one-meter-high storage tank (sun bath) whose water storage capacity is one-half of the water requirement of a single fish pond, and the bottom (ie roof) surface is resurfaced with No. 200 cement mortar. , 3 cm to 5 cm thick to prevent leakage. After the bottom of the pool and the side wall are wiped, the plain cement paste is used to smooth the surface. Make a side wall (24cm, 12cm, 6cm, small bricks, side walls, brickwork, and easy to walk and place flowerpots), and arrange drainage pipes.
Second, set up the arbours to prevent the summer sun from direct water temperature is too high, need to set up arbors. Shade sheds should be 1m to 2m above the pool wall and have a certain resistance to wind and rain. The sheds are shaded with vines, sponge gourds, squash, and other cashew crops or flowers.
3. Five days before stocking, the fish should be disinfected with 20 grams of bleaching powder per cubic meter of water. The goldfish was sterilized by dipping the fish body with 3% saline before entering the pool. Generally, longan, high-headed, and long-day species are stocked per square meter, with body length of 2 cm 100 to 200, body length 5 cm 50 to 100, body length 10 cm 10 to 20. Fry can either breed or purchase it.
Fourth, feed for feeding goldfish is omnivorous fish, productive farming mainly rely on artificial compound feed. Here we introduce the preparation methods of several artificial compound feeds: (1) Ground the rice bran and bran, mix them with steamed shrimp powder, and then pulverize them into pellets after cooling; (1) Use 40% fish meal and 60% After the wheat bran is mixed, it is mixed with 0.1% yeast powder, mixed with 1%-2% binder, steamed and processed into pellets and dried; (3) with wheat flour, bean cake, fish meal and shrimp. The powder was ground and mixed into a paste. After adding the alum to dryness, it was pulverized (float). Feed each day 1 afternoon. Feeding capacity should be based on the "three look" flexible control. A look at the food situation, such as feeding quickly eaten, should be increased, otherwise it should be reduced; second look at the weather, sunny and more cast, hot and rainy days less vote or not cast; 3 look at the fish activity, the fish is strong, water temperature When appropriate, more investment, when the incidence of less vote or not vote, will not float when floating or floating head.
5. The purpose of changing the water and water correctly is to keep the water clean and have enough oxygen. Observe with naked eyes, the color of water is yellow or pink gray or black and green, stench and sour, and the fish also floats during the day. Change the water in time, or the fish will become sick and die. The water source for goldfish on the roof is tap water, such as changing the water from 1/4 to 1/3 of the fish pond, which can be directly sprayed; if the fish pond is completely dry and the water is changed, the fish should be put back immediately, then it is necessary to add water for more than 1 day after sun exposure. Water in the pool to avoid excessive chlorine in tap water and excessive temperature difference. When you change the water, you must avoid rushing. If it is better to use the suction pipe to suck the dirt and add new water, it is best to keep the light green color of the fish pond.
6. Prevention and treatment of diseases The most common diseases of pools of goldfish are saprophytic disease, gill disease, vertical scale disease and burning tail disease. The comprehensive measures for prevention are: 1. To clear the pool and disinfect the drug before stocking; 2. To immerse and sterilize the fish before stocking; 3. To add antibacterial drugs to the feed; 4. To keep the pool water green and not corrupt; The incoming goldfish should be isolated and observed separately to prevent disease; 6. Strengthen the management of vines such as grapes, make it grow and flourish, enhance the shadowing effect; 7. Found fish disease, timely symptomatic treatment.
