3. The price of small and medium-sized reservoirs for fertilizing fish has been increasing along with the increasing prices of some markets, and some small and medium-sized reservoirs have also been converted from the original people to “semi-intensive cultureâ€. This model mainly uses fertilized fish. Artificial feeding is supplemented. In Hubei, Sichuan, Chongqing, Hunan, Henan and other places, the yield is relatively high, generally high yield per mu up to 500-800 pounds.
1. Breeding conditions The reservoir is well-watered, with open water surface, strong sunlight, and infrequent water exchange in the reservoir. It has facilities to stop fish and the water depth should not be too deep.
2. The breeding area is characterized by a single area of ​​tens, hundreds, or even thousands of acres, which is easy to control and develop by man. The water body is large and the water quality is good.
2. Breeding species II. Pond high-density culture (mainly feed on concentrate feed)
With the promotion of compound feeds, many farmers have been feeding from the pure feeding of white peony to the intensive feeding of grasses, cockroaches and herrings, but fertilizing fish is still necessary, and flowers and white ash still occupy a certain proportion. Can also improve the overall efficiency of breeding.
Let us briefly introduce the model of 1200 kg per mu:
1. Farming area: 5-30 mu, water depth 1.5-3 meters, close to water source
2. Breeding characteristics Use high-quality exogenous nutrition, such as compound feed, to provide adequate nutrition for the fish. Using the residue in the feed and fish to excrete feces, with a small amount of fish fertilizer to achieve the purpose of fertilizer, promote the growth of white peony.
3, cultured varieties of white peony, alfalfa, grass carp, herring, eel, oyster, yellow croaker polyculture.
4. Facilities and settings 鲢 300 tails/acre 鳙 50 tails/acre grass carp 150 tails/mu octopus 90 tails/acre 鳊400 tails/acre mullet 400 tails/acreray squid 250 tails/acre
5, before stocking, prepare fish species for 7-10 days before stocking, select sunny noon with lime or drug clear pond, fish species before stocking are disinfected with drugs.
6, aquaculture management 1 domesticated breeds.
2 Feeding adheres to the principle of “three observations and four determinationsâ€, that is, “see weather, water color, and fish school activitiesâ€, and “time, fixed-point, quantitative, and qualitativeâ€.
3 water quality management, to maintain water quality fat, live, tender, cool, when the transparency of more than 35 cm, the appropriate top dressing, with "Tianchen fishing fat" 2 ~ 3 kg / acre, Quanchiposa, you can achieve fertilizer purposes, Can play a role in regulating the quality of water, reduce flooding, prevent fish disease.
4 pay attention to open aerator and whole pool disinfection, to minimize the occurrence of fish disease.
7. After fishing for one year, it is basically 300 lbs./mu, 300 kg/mu, 200 kg/mu grass carp, 180 kg/mu bald fish, 200 kg/mu mussels, 130 kg/mu mussels, stingray 30 kg/mu, reaching 1100 to 1200 kg/mu.

3, facilities and settings generally é²¢80-85%, é³™15-20%, appropriate amount of grass carp, stocking seed size to be larger, generally each 3 to 4 more than two, large can be put eighty two to a pound of specifications Depending on the specific conditions of different reservoirs, the eutrophic or full fertilization can be applied to 150 to 250 tails/mu, and ordinary reservoirs to 100 to 150 tails/mu. The fish species to be put on the market are required to have neat specifications, robust physique, and no disease or injury. The application of "Tianchen Fishery Fertilizer" implements round-catching rotation and proper management. The per mu output can reach 600-850 pounds.
4, before the preparation of fish species need to be disinfected by drugs. The water body of the reservoir before stocking needs to be invested with a large amount of agricultural fertilizer or “Tianchen Fishery Fertilizer†for cultivation.
5, Fertilization Management 1 Seedlings before and after the stocking application of base fertilizer, can be combined with traditional fertilizer and "Tianchen fishing fat" application. "Tianchen fishing fat" 2-3 kg per mu plus 10 kg of fertilizer.
2 If the stocking density is high, then the pond must be kept full during feeding. The general transparency is preferably 25 to 35 cm.
When the water temperature is 20°C, plankton can reach a peak 4 to 5 days after application of "Tianchen Fishery Fertilizer", which can be maintained for 7 to 8 days. Every 13 to 15 days, topdressing is applied once again. When about 25°C, fertilization takes place 5 to 6 The day can be restored to the level before fertilization, and can be maintained for 6 to 7 days. Top dressing is applied once every 10 days. From June to August, plankton reached its peak 3 to 4 days after fertilization, and returned to the level before fertilization 6 to 7 days. Therefore, fertilize 4 to 5 times a month, 3-5 kilograms each time, and fertilization after September. cut back.
3 Large-surface fertilizer should pay attention to applying fertilizer in the bay and windward as far as possible, and fertilization time is best applied at noon on sunny days.
4 When fertilizing, the pH should be controlled at about 7.3 to 7.8. If it is acidic, it can be used first and then fertilized with quicklime. It should be separated by 2 days.
