How to breed osmanthus fish? Can cinnamon fish be farmed and how to breed it

The first breeding technology of osmanthus fish, is how to choose the pond, generally for the breeding of osmanthus fish, the choice of the pond is a certain condition, generally this set of areas are 2 to 4 acres, and the water depth is about two meters, mainly rectangular in the water quality is also rectangle-based, 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, the school equipment is very complete.

The second breeding technology when breeding osmanthus fish, is the cultivation of some bait fish, in order to make the osmanthus fish grow more rapidly, bring higher benefits, you can choose some silver carp, white carp, tuantou bream, silver carp, silver carp and other fish fry as bait, the use of the idle period of breeding osmanthus fish, cultivate some bait, can feed the osmanthus fish, provide some natural food, and then put the osmanthus fish into the pond when stocking, the first 20 days can put some bait.

The third breeding technology in the cultivation of osmanthus fish ten, is how to stocking the osmanthus fry, generally for the osmanthus fry screening time is in June every year or so, and the stocking specifications are required to be 6 to 10 cm best, this time in June is the temperature of the osmanthus fish growth is more suitable, and their survival rate and growth rate are very high, generally the stocking amount per mu is about 500 to 800.

The fourth in the breeding of osmanthus fish is the breeding technology, that is, how to feed the bait fish, in order to strengthen their disease resistance and their growth rate, generally in the breeding of adult osmanthus fish is to be able to feed them every day, if some bait is too little will cause them to appear hungry, which will greatly affect the growth of the osmanthus fish, and even let them kill each other, resulting in a lot of losses.

The pond for raising osmanthus fish requires good bottom quality, the bottom of the pond is about 10 cm of silt, the pond water quality is medium fertilizer, and the pond for raising osmanthus fish should be equipped with drainage and irrigation and aeration equipment. Artificial induction: The artificial induction season is from May to August.

The injected drugs include HCG, LRH-A and fish pituitary gland, which can be mixed or injected separately, and the dose of male fish is halved, and the base of the pectoral fin is injected at one time. Before carrying out broodstock breeding, it is necessary to determine the breeding object. At present, the main breeding species of Aohua fish are big-eyed mandarin fish, mandarin fish, spotted mandarin fish, etc., among which Mandarin fish is the most common and has the best breeding effect.

In the process of intensifying cultivation, we should pay attention to two points: first, there must be sufficient bait fish; The second is to ensure good water quality, and it is best to flush water regularly to create an environment of micro-flowing water.

Questions. Natural ditches have flowing water all year round.

It can be raised, because fish are more active in living water.

Breeding pond: the area can be between 3-8 acres, and it needs to be built in a place with good water quality. Water depth:

At least meters, the water depth can be increased appropriately in winter. Food: Guiyu is a typical carnivorous fish, and it is often used as their food for small fish, such as white carp, which can be cultivated at the same time as the cultivation of Guiyu.

Water quality: The water needs to be changed regularly to keep the water quality clean. Generally, it is replaced once a week to ensure that the transparency of the water is more than 40 cm.

Guiyu is one of the common fish living in our country, and it belongs to the order Perciformes from the perspective of category. Wild osmanthus fish are widely distributed in the waters of various regions of China. In addition, Guiyu is also a fish that can be raised in captivity.

The economic value of Guiyu is high, because they have a good taste, rich nutrition, and the number of fish bones is not particularly large, so it is widely popular. Therefore, on the whole, the breeding area of osmanthus fish is still relatively large, and many farmers choose to breed osmanthus fish. Farmed cinnamon can be used in both the south and the north, because the fish adapt well to water temperatures, even at relatively low water temperatures.

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 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 more than 30 cm.

3. Cultivation of bait fish molds.

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. It is also possible to mix some fast-reproducing fish 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 method of spacing bait fish, in the early and late stage of breeding, every 7 10 days to feed, the middle of every 5 days or so to feed once, should maintain the number of mandarin fish and bait fish ratio of 1:5 10, Dan Chong sedan bait fish too little, will affect the feeding and growth of mandarin fish, too much is easy to cause hypoxia floating head, is not conducive to 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.
