How should Guiyu be farmed? What should I pay attention to when breeding?

Cultivation of forage fish: According to the principle of good palatability and low economic cost, silver carp, white carp, giant mac, silver carp, bighead carp and other fry species can be selected as bait fish. Use the idle period before stocking in the osmanthus pond to cultivate early bait fish, can breed carp or bream fry, can also be stocked 20 days before the osmanthus fish are stocked with all kinds of fry, the stocking volume per mu is 400,000 to 600,000.

The feeding method is to feed with soy milk or other feed, and the bait fish should be specially raised in the middle and late stages. It is advisable to adopt the method of multi-pond high-density feeding, divide the fishing, and gradually reduce the dilution, so as to ensure the synchronous growth of forage fish and mandarin fish.

<> in the process of breeding osmanthus fish, we should pay attention to the feed, during the breeding period, in order to absorb the balanced nutrition of osmanthus fish, we should feed a variety of feed fish. In the selection of feed, the fish food should be based on palatability, and the size should be small but not too large, so that the large and small osmanthus fish can ingest the required food in real time. Others should also pay attention to the amount of feeding during the breeding period, should accept a small amount of scale, generally feed 5 7 times a day, increase the number of feeding in winter, that is, when the water temperature is low, the amount of osmanthus fish is less, if you feed too much, it will form feed waste, and some useless bacteria will occur in the pool.

When breeding osmanthus fish, we must choose a suitable breeding place, and it is advisable to take the pond with open terrain, ventilation and sunshine, away from the crowd and convenient transportation. Before breeding, the debris in the pond should be cleaned up, and then disinfected and sterilized with quicklime. It is also necessary to seal the inlet and outlet with fishing nets.

The breeding of mandarin duck fish also needs to control the breeding density to avoid the phenomenon of mandarin duck fish competing with each other and dying. The breeding density is best controlled within 2000 per mu, and it is also necessary to select mandarin fish with healthy growth and strong immunity to put fish fry.

Do a detailed explanation of the problem for a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, the like is the biggest help to me, thank you.

We must pay attention to the breeding density, and then in the breeding process must choose high-quality water resources, should also be equipped with aerators, to choose healthy fish fry, in the process of breeding must ensure the temperature, the temperature should be controlled at about 22 degrees, to feed the fish at a fixed time, in the process of breeding to replace water resources in a timely manner, but also should do a good job of disinfection and sterilization.

Attention should be paid to the frequent adjustment of water quality, but also to pay attention to the surrounding temperature and humidity, should also pay attention to the proportion of bait, and should also pay attention to the cleanliness of water quality when breeding, but also pay attention to whether there are parasites in the water of mandarin fish. It is also necessary to pay attention to the growth environment of mandarin fish, and also pay attention to the problem of sunburn.

Probably need to find a big pond first, and then you can put the osmanthus fish in the pond, and then pay attention to the fry can not be too much, and pay attention to the need for peroxygen, but also to properly clean the fish pond, the need to pump water in time and the like.

1. Breeding pond: Breeding osmanthus fish is generally used in breeding ponds. The breeding pond needs to be large enough, and it is generally appropriate to control it between 3-8 acres. The breeding pond also needs to be built in a suitable place, preferably close to the water source, the drainage and irrigation are more convenient, and the water quality is better.

2. Water depth: Breeding osmanthus also needs to pay special attention to the water depth, because the osmanthus likes to inhabit the waters. Therefore, the water in the breeding pond should not be particularly shallow, generally speaking, it must be at least a meter deep.

In winter, the depth of the water can also be appropriately increased, which is more conducive to the winter.

3. Food: Breeding osmanthus fish needs to prepare enough food for them, so that their development status will be good. Guiyu is a carnivorous fish, and some small fish are their favorite food.

Fish such as crucian carp are often used as feed for osmanthus fish, and this kind of feed fish can be cultivated at the same time as the osmanthus fish is raised, and sufficient feed can be provided for the osmanthus fish.

4. Water quality: The water quality of the fish is also very important, the water quality is too dirty, which will seriously affect the growth of the fish, and may cause them to get sick. In order to ensure the quality of the water, the water needs to be changed regularly.

In general, it should be changed once a week to keep the water transparent at more than 40 cm.

1. Habits.

Mandarin fish is a typical carnivorous fish, and when artificially fed, it can be fed with filial piety or dead fish, dead shrimp, etc. The male fish matures at the third instar and the female matures at the fourth instar, and its growth rate is relatively fast, up to 50 100 grams in the current year, about kilograms in the second year, and 1 kg in the third year.

2. Pond conditions.

The pond for mandarin fish adult fish breeding should be 3 8 acres, the water depth should be more than 1 meter, the water depth should be about 1 meter in summer, the bottom quality is best sandy loam, less humus, sufficient water source, fresh water quality, and better flowing water. It is required that the dissolved oxygen content of the pool water is more than 5mg l, the pH value is 7 8, and the transparency is 30 cm to be cleverly slag.

3. Bait fish breeding.

The area of forage fish culture is 3 to 4 times that of mandarin fish ponds. From the perspective of palatability and economy of mandarin fish, baige fish are generally selected as silver carp, crucian carp and other species, and the stocking density is 30.5 million fry per mu. After the fry are stocked, they do not need to be fed immediately, and when the number of zooplankton decreases and the fry are foraging around the pond, they are fed with soy milk or other feed.

In the early stage of rearing, the feed should be added when it is exhausted, and in the later stage, the size of the forage fish should be controlled, and the length of the forage fish should be controlled between 1 2 and 1 3 of the body length of the mandarin fish.

Mandarin fish fingerlings are generally stocked with 8 10 cm, and forage fish should be controlled at 3 4 cm.

4. Stocking of mandarin fish fingerlings.

When raising mandarin fish alone, 800 1000 mandarin fish fingerlings with a size of 8 10 cm can be placed per mu. Some fast-reproducing fish can also be mixed in mandarin fish ponds as live feed. Generally, 200 400 pairs of tilapia broodstock or 60 two-winter-old crucian carp are stocked per mu.

Use a thin net to divide the fish pond in half and raise mandarin fish on one side.

Fish, while raising other fish, so that the breeding juveniles pass through the thin nets to become mandarin fish feed, and at the same time, the activity of mandarin fish does not hinder the quiet reproduction of other fish.

5. Feeding management.

1) bait: the use of interval feeding fish method, in the early and late breeding period, every 7 10 days to feed, the middle of every 5 days or so Liang Hong feeding, should keep the number of mandarin fish and bait fish ratio of 1:5 10, too little bait fish, will affect the feeding and growth of mandarin fish, too much is easy to cause hypoxia floating head, is not good for the growth of mandarin fish.

2) Water quality management:

It is necessary to add new water frequently, especially in June and September, and add new water every 5 or 7 days, 15 20 cm each time, so that the pool water remains fat, lively, refreshing and tender, and promotes the healthy growth of mandarin fish. Submerged plants such as bitter grass and black algae can be planted around the pond to provide a hiding place for fish and at the same time play a role in purifying water quality. Sprinkle quicklime water every 15 20 days for 15 20 kg each time.

Open the aerator in a timely and reasonable manner to increase the amount of dissolved oxygen in the pool water and prevent the fish from hypoxia, and at the same time, some aerators should be prepared, which can be used for rescue when the fish is hypoxic floating head.
