There are many breeds of freshwater fish, and there are a variety of farming models. There are more than a dozen farming models that are formed according to aquaculture water conditions and aquaculture species and other conditions throughout the country. These are not described one by one here, focusing on the introduction of several fish farming methods. Culture mode, and introduce fertilization techniques and methods.
There are many breeds of freshwater fish, and there are a variety of farming models. There are more than a dozen farming models that are formed according to aquaculture water conditions and aquaculture species and other conditions throughout the country. These are not described one by one here, focusing on the introduction of several fish farming methods. Culture mode, and introduce fertilization techniques and methods.
First, the pond fish fertilization
In some areas of Central China, Sichuan, and Chongqing, many ponds are still carrying out the traditional breeding mode of the main eel and eel.
ã€Cultivation conditions】 Requirements area 5 to 20 acres, depth of 1.5 to 3 meters, bottom mud 10 to 20 cm, close to the water source, irrigation and drainage convenience.
[Culture characteristics] Use of material circulation between organisms to reduce production costs, after the application of fish fertilizers, to promote the reproduction of plankton to increase the primary productivity of the waters. Through the photosynthesis of phytoplankton, the dissolved oxygen in water is increased, the decomposition of organic matter is accelerated, a large number of food organisms are provided for fish, the growth of fish is promoted, and the productivity of fish ponds is improved.
[Cultivated species] The main raising whitefish is accompanied by a small amount of mid-lower fish such as grass carp, grass carp and grasshopper.
Seed setting: The stocking ratio is roughly as follows: 鲢70-80%, 鳙5 110%, grass carp 10%, squid 5%, stocking size 11.6 ～ 13.2 centimeters in autumn, mainly nesting in summer flowers (per acre Put 200 to 300 tails.) Insufficient part of the year will be refilled with a part of the spring film. Within the range of 700 to 800 tails per mu, 17 to 18 kg in weight.
ã€Preparation for stocking】 7 to 10 days before stocking, choose clear lime pond or drug clear pond at noon on sunny days.
ã€Catering management】
1 Applying basic fertilizer: From mid-April to mid-May, the “Tianchen Fish Fertilizer†or traditional fertilizers will be applied to the pond in stages. At this time, fertilization amount is 2 to 3 times of normal fertilization, and the standard of cultivation is good water quality. Slough ponds and new digging ponds should be fertilized with more water;
2 top dressing: After June, it is necessary to fertilize the fertilizer to ensure that the water. As the temperature rises, it is not appropriate to apply traditional fertilizers such as agricultural fertilizers and should apply “Tianchen fishing manureâ€. Generally, 4 to 5 times a month in June, each time 2 to 3 kg/mu, 7 to 8 months need about 5 to 7 times a month, each time 2 to 3 kg/mu, according to the specific circumstances of the decision to increase or decrease. Declined after September.
3 Fertilization Management: After entering May, it is often necessary to add new water to the pool. Every 20 to 30 days, quicklime is used to keep the water fresh and prevent various diseases. The pH is usually kept between 7.3 and 7.8.
ã€fishing】
According to the above method, after one year of feeding, the general ferret can reach 0.75 to 1.0 kilograms, and kang can reach 0.75 to 1.2 kilograms. Grasp the favorable timing for a balanced listing and catch up.
Second, high-density pond culture (mainly to feeding concentrate feed)
With the promotion of compound feed, many farmers have been feeding from the simple feeding of white peony to the intensive feeding of grasses, cockroaches and herrings, but fertilizing fish is still necessary. White locust still occupies a certain proportion.
Let us briefly introduce the model of 1200 kg per mu:
ã€Cultivation conditions】
Area 5 to 30 mu, water depth 1.5 to 3 meters, close to water
ã€Culture characteristics】
Use high-quality exogenous nutrients, such as compound feeds, to provide fish with adequate nutrition. Using the residue in the feed and the fish to excrete the feces to achieve the purpose of fertilizer, and promote the growth of the white peony.
[cultivated species]
White clams, clams, grass carp, herring, cockroach, clams, and stingrays are raised.
ã€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/ acre sturgeon 250 tails/acre
[Prepare for restocking]
7 to 10 days before stocking, select sunny days at noon to use lime or drug clear pond, fish species before stocking are disinfected with drugs.
Fertilization Management
1 Tame the cultured species.
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.
ã€fishing】
After one year of raising, it is basically 300 kg per mu, 500 kg per mu, grass carp 200 kg per mu, herring 180 kg per mu, carp 200 kg per mu, carp 130 kg per mu, and stingray 30 kg per carp. Mu, reaching 1100 to 1200 kg/mu.
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.
ã€Cultivation conditions】
The reservoir is well-watered, the water surface is open, and the light is strong. The water exchange in the reservoir is infrequent and there are facilities to stop the fish. The water depth should not be too deep.
ã€Culture characteristics】
A single area of ​​tens, hundreds, or even thousands of mu is easily controlled and developed by humans. The water body is large and the water quality is good.
[cultivated species]
Grasshoppers, clams, and grass carp are the dominant species, raising a small amount of expensive fish.
ã€Facilities and Settings】
General é²¢80-85%, é³™15-20%, appropriate amount of grass carp, stocking size of seedlings to be larger, generally each 3 to 4 more than two, large can be put eighty two to a catty size, the number of different reservoirs Specific circumstances. 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.
[Prepare for restocking]
Fish species need to be disinfected with 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.
Fertilization Management
1 Apply base fertilizer before and after stocking, and combine traditional fertilizer with “Tianchen Fisheryâ€.
2 If the stocking densities are high, then the ponds must be kept full during feeding. The general transparency is kept at 30-40 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 after 3 to 4 days of fertilization, and returned to the level before fertilization 6 to 7 days. Therefore, fertilization should be applied at least 4 to 7 times a month, and the number of fertilization after September should be reduced.
The 3 large surface fertilization should pay attention as far as possible in the bay, upwind of the fertilization, 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 the acid is used, the whole pool of lime can be splashed and then fertilized. Note that it should be separated by 2 days.
