Hello, you can take a look, or go to the bookstore to find related books.

1. Pond conditions: Pond breeding osmanthus fish should choose a pond with leeward and sunny, sandy loam soil bottom and flat bottom. 2. Stocking fry:

When stocking osmanthus fish, put it in the water with a plastic bag for 20 minutes to slow down the seedlings. 3. Feeding management: feed the osmanthus fish once every 7-10 days.

4. Precautions: Pay attention to the need to start the machine in time to increase oxygen when there is a thundershower.

1. Pond conditions

Breeding osmanthus fish should choose a pond with leeward and sunny, sandy loam soil bottom, less silt, and flat pond bottom, dig a shallow ditch 30-40 cm deep around the pond to facilitate the fishing of osmanthus fish, and then expose the bottom of the pond to disinfect, and configure an aerator.

2. Stocking fry:

Before stocking osmanthus fry, first drain half of the pond water and then fill with new water, the water level gradually increases to more than rice in the later stage, and put it into the water for about 20 minutes together with the plastic bag when stocking, in order to slow down the seedling treatment, and the stocking time is appropriate in June every year.

3. Feeding management

The suitable water temperature for osmanthus fish feeding is 23-28 degrees, in this range, with the increase of water temperature, its feeding intake increases, and the growth rate will also accelerate, feeding 1 bait every 7-10 days in the early and late stages, and feeding every 5-7 days in the middle stage.

4. Precautions

Osmanthus fish like fresh water quality, low oxygen tolerance is poor, during the breeding period to change the water regularly, keep the bottom of the pond transparent, and according to the weather changes and water quality, flexible grasp of the aerator start time and times, pay attention to thunderstorms to start the aerator in time to increase oxygen.

The feed of osmanthus fish is mainly based on plant feed, supplemented by animal feed such as small fish and insects. The main feed ingredients are soybean cake, sesame cake, corn flour, etc., and additives such as vitamins and minerals can be added in moderation. The following is the breeding technology of Guimeng nuclear fish:

1.Select suitable waters for farming. It is necessary to choose a water area with slow water flow, stable water temperature, good water quality and sufficient water source as a farm.

2.After site selection, the water area should be cleaned up and treated. In order to ensure the sanitation of the water area and the smooth flow of water.

Remove all toxic and harmful impurities and harmful microorganisms in the water body. 3.Do a good job in the selection of fish fry, lack of digging and introduction.

Good varieties of fry can be selected, and after introduction, proper quarantine and isolation should be carried out to prevent the spread of the disease. 4.Do a good job in water quality management.

Water quality should be measured regularly, and water bodies should be replaced and cleaned up in a timely manner. 5.Scientific breeding.

Reasonable bait management methods should be adopted to ensure that osmanthus fish can obtain sufficient nutrients and achieve good growth rate and health status. 6.Control the disease.

Summary. Dear, hello, I am glad to answer for you, mandarin fish adult fish culture is to raise 3 cm mandarin fish fry or 6-8 cm fingerlings into commercial fish weighing about 500 grams. This process takes about 180 days.

The length of feeding time depends on whether the forage fish are sufficient and palatable, whether the water quality is good, and whether the management is appropriate. At present, the main methods of aquaculture include pond main culture, adult fish pond (small reservoir) polyculture, circulating water aquaculture, etc.

Qinwan Town, when stocking osmanthus fish, it is necessary to first shoot the shed in the pond subject to stock silver carp, bighead carp, rohu, mrigal, rohu, crucian carp and other bury coarse fry as the early bait fish of osmanthus fish. Can be fed with peanut bran, wheat husk and other roughage every day, after 15-20 days of cultivation, when the bait fish grows to a centimeter body length, you can first use copper sulfate and strong chlorine insecticidal disinfection, and then put 2-3 cm size osmanthus fry breeding.

Dear, the breeding cycle of osmanthus is 3-4 years of hail. When breeding osmanthus fish, the choice of pond is very important, the general pond area is 2-4 acres, and the water depth is about 2 meters, and the hole is mainly rectangular. And the water quality of the pond needs to be very clean, the mud at the bottom of the water is less or none, and some commonly used drainage and irrigation facilities must also be prepared.

Summary. Under different water temperature conditions, the feeding rate of osmanthus is different, and the analysis of the feeding rate of osmanthus fish in that year is as follows: the feeding rate is 20%-30% from June to July, 20%-15% from August to September, and the feeding rate is about 10%-5% from October to November.

Generally, it takes 40-50 days to cultivate to 12cm (50g), 4000-5000 per mu. (Here is the standard seedling, and then stocked in the pool) Judgment of the number of forage fish in the pond: (If a 3nm osmanthus fish does not eat 1 bait fish within 2 days, there will be problems) When the forage fish in the pond are sufficient, the osmanthus fish chase the bait fish at the bottom of the water, so there are only small splashes on the surface of the pond.

When listening closely, the water sound made by the fish chasing the feed fish is smaller, and the interval is larger. If there is not enough forage fish in the pond, the osmanthus fish chase the forage fish to the upper layer of the water, so the splash is larger, and the sound is more frequent and louder.

The Zhao circle is generally cultivated from the dynasty, and it takes 40-50 days to cultivate to 12cm (50g), and 4000-5000 pieces per mu.

(Here is the standard seedling, and then stocked in the pool) Judgment of the number of forage fish in the pond: (If a 3nm osmanthus fish does not eat 1 bait fish within 2 days, there will be problems) When the forage fish in the pond are sufficient, the osmanthus fish chase the bait fish at the bottom of the water, so there are only small splashes on the surface of the pond. When listening closely, the water sound made by the fish chasing the feed fish is smaller, and the interval is larger.

If the forage fish in the pond is insufficient, the osmanthus fish chase the fodder fish to the upper layer of the water, so the splash is larger than the spike, and the sound is more frequent and louder.

If you find a group of osmanthus fish chasing forage fish by the pool, it means that the forage fish in the pond have basically been eaten.

The first culture technique for cultivating osmanthus is how to select pondsGenerally, when breeding osmanthus fish, there are certain conditions for the selection of ponds, generally this set of areas are 2 to 4 acres, and the water depth is about two meters.

Mainly rectangular, for the water quality is also rectangular, and the water quality needs to be very clean, the mud at the bottom of the water is less or there are no important facilities for drainage and irrigation, and the school equipment is very complete.

The second breeding technique in the cultivation of osmanthus fish is the cultivation of some forage fishIn order to make the osmanthus fish grow more rapidly and bring higher benefits, you can choose some silver carp, white carp, bream, silver carp and other fish fry as bait.

During the free period of breeding osmanthus fish, some bait can be fed to provide some natural food, and then when the osmanthus fish is put into the pond for stocking, some bait can be put in the first 20 days.

The third breeding technology in the cultivation of osmanthus fish is how to stocking the fry of osmanthus fishGenerally, the screening time for Guiyu fry is around June every year, and the size of stocking is required to be 6 to 10 cm.

This time is June is more suitable for the growth of osmanthus fish for temperature, and their survival rate and growth rate are very high, generally the stocking amount per mu is about 500 to 800.

Fish pond environment: Choose to build osmanthus fish ponds in ponds with little or no sand on the bottom. Water Quality Requirements:

The amount of dissolved oxygen in the water is more than 5 milligrams per liter of water, and the pH value is between 7-8. Fry stocking: Fry of size centimeters are selected for stocking.

Disease prevention: Regularly sprinkle disinfectants such as bromochlorohydantoin on pool water.

1. Fish pond environment

When cultivating osmanthus fish, choose to build a fish pond around the pond with little or no sand at the bottom, convenient drainage and irrigation, away from pollution, and abundant water resources, the water level depth is between meters, and the fish pond is best rectangular, and the anti-escape device is installed at the inlet and outlet.

2. Water quality requirements

Osmanthus has higher requirements for water quality, to ensure no pollution, the amount of dissolved oxygen in the water is more than 5 mg per liter of water, and the pH value is between 7-8, the visible transparency can not be less than 30 cm, and the quicklime is splashed every 10 days to adjust the pH value of the pool water.

3. Stocking of fish fry

Osmanthus fish is generally stocked in June in summer, to select the size of the size of the centimeter of fry, the density of each mu is 800-1200, soak in salt water for 10 minutes before stocking, the water temperature is kept at 23-28 degrees, which is conducive to the foraging and normal growth of the fry.

4. Disease prevention

During the breeding of osmanthus fish, it is easy to be infected with bacterial gill rot, parasitic diseases and hemorrhagic diseases, and regularly splash disinfectants such as bromochlorohydantoin or chlorine dioxide into the pool water**, add bleeding and other agents to the bait, and feed them continuously for 5 days**.
