Many people want to invest in octopus farming. What is the prospect of octopus farming now?

Octopus is widely known as octopus and octopus. Compared with other octopus species, octopus has strong adaptability to aquaculture, wide distribution, strong spawning ability and high nutritional value. Therefore, octopus has become one of the most popular cephalopod species. It looks ordinary, but its aquaculture is not easy. Due to the transition from the planktonic stage to the benthic stage, the mortality rate of octopus is very high. , The octopus seedlings currently used are all from the sea. Although there are precedents for the trial of artificial breeding of octopus at home and abroad, they have not been mass-produced and put on the market in the end.

You need to go deep into the market and enterprises, understand their needs, and then make a positioning, what varieties the market needs, what season is the peak season, and once you figure it out, you can carry out planned breeding according to market demand and provide the varieties the market needs. In breeding, sales are the key link. You can use the sales channels of local farmers and the extensive connections you have established over the years to sell your poultry. You can also go to nearby large and medium-sized cities to contact large sales companies and establish a sales network. If you do these things well, you will have a good idea.

We have been able to persist for so many years because the catch in the sea is getting smaller and smaller, and the demand is getting bigger and bigger. Zhu Jianguo said that the edible part of Hukou is as high as 95%, rich in protein and high in fat, which has the effect of nourishing blood and qi. There is a large market at home and abroad, especially in Japan and South Korea, which need to import thousands of tons of frozen Hukou products every year. The breakthrough of artificial breeding and full artificial breeding of octopus will lay a good foundation for the real large-scale production of octopus, promote the adjustment and upgrading of the structure of Putian aquaculture industry, and add a new variety to the aquaculture industry in our province, so that more fishermen can benefit.

The editor has made a detailed interpretation of the problem, and I hope it will be helpful to everyone. If you have any questions, you can leave me a message in the comment area. You can comment to me more. If there is anything wrong, you can also interact with me more. If you like the author, you can also follow me. Your likes are the greatest help to me. Thank you everyone.

The future prospects are very good, and many young people will give up their white-collar jobs to work in this industry, and they can really make a lot of money. This shows that the future development is really good, and there will be an octopus market in the future.

Currently, the prospects for octopus farming are not very good, because the catch in the sea is getting smaller and smaller, while the demand is increasing. In addition, the survival rate of octopus in farming is relatively low, and the mortality rate is very high, which can easily lead to technical errors.

The prospects are not good. The mortality rate of farmed octopuses is very high. Once an operation error occurs, the loss will be very large, and it will be very troublesome when farming octopuses.

The prospects for octopus farming are not very good now, because it is very troublesome to farm octopuses, and the mortality rate of octopuses is also very high. Once an operation error occurs, there will be losses.

Octopus is common in seafood markets. What are the methods for breeding octopus?

Octopus is a temperate mollusk that lives underwater. It is suitable for water temperatures not lower than 7°C and seawater specific gravity of 1.021** *. It will die in low salinity environments. It is widely distributed in tropical and temperate waters around the world. It is distributed on the north and south coasts of my country. The fishing season is divided into spring and autumn, from March to May in spring and from September to November in autumn. Let's take a look at the artificial breeding technology of octopus!

1. Octopus plastic bottle cultivation

Octopus plastic bottle culture is to put wild young octopus into a 500 ml discarded beverage bottle with fine holes, seal the bottle mouth, hang them in series with ropes, put them into the sea to hang naturally, and add floats at appropriate intervals to achieve better results. Although this method is simple, octopus grows slowly and is suitable for breeding in sea areas rich in plankton.

2. Cement pond culture method

The cement pond culture method is to use 8 cement ponds of about 20 square meters and 80 cm deep, spread 20-30 cm thick sea mud on the bottom of the pond (50 cm thick in the center of the pond), inject precipitated seawater, and throw octopus larvae of 10-50 grams (average about 40 grams) from the beach in turn. Feed once every afternoon, and the bait is live crabs (individuals) dug from the beach. During the breeding process, the water is changed once a day with precipitated seawater. As long as the water is changed in the hot season, the octopus will not die. After about 6 months of breeding, the number of individuals before capture is generally 50 to 100 grams (average about 70 grams). This method is simple and easy, suitable for small-scale family breeding.

3. Octopus Purse Farming

Octopus seine farming is a method of farming octopuses in a dense net of about 3,000 square meters on the tidal flats in the mid- and high-tide areas. When the tide is low, the octopuses hide in the holes, but the net of the seine is higher than the tide level to prevent them from escaping. This method is simple and low-cost, but it requires a lot of work and a large area of ​​digging and catching when harvesting.

4. Octopus cage farming

1. Cage setting: Cage culture (3.94m × 1.82m × 0.9m) can be adopted. The mesh size is smaller than the mesh size of a single fish. It is necessary to add a net cover to prevent the octopus from escaping. Most of them are cultured in harbors with calm waves and the suitable water temperature is 15 ~ 23℃. Generally speaking, they are mostly cultivated in spring and summer (June and July) and autumn (October to December).

2. Stocking of seedlings: Seedlings caught in cages are suitable, but bottom trawls can also be used. The number of seedlings varies according to water temperature and flow. 36 to 42 kg of seedlings per cubic meter of large cages, and 25 to 30 kg of seedlings per cubic meter of small cages. To prevent seedlings from killing each other, seedlings of the same batch should be placed in cages, and it is advisable to wait until the seedlings are filled with food before putting them in the cages.

3. Feeding: You can feed cheap fish and shellfish, or you can feed frozen fish, but it must be fresh. When the bait is retained for a long time, it is best to reduce or stop feeding for 1 to 2 days, which will cause water pollution. If the bait is stopped for more than 3 days, they will kill each other. When the water temperature is around 13℃, the feeding behavior is irregular, and the octopus will not eat below 7℃.

4. Breeding management: The cage culture method is suitable for large-scale breeding. After two months of cultivation, the survival rate of caged seedlings is 70-80%, and the survival rate of fishing seedlings is about 50%. The mortality rate of cage seedlings reaches 20-30% on the 15th day, and then the mortality rate gradually decreases. After 15 days of breeding, the octopuses are divided into three types: large, medium and small, and placed in different cages. Clean the cages every 15 days in spring and autumn, and every 30 days in winter.

The above is an introduction to the artificial breeding technology of octopus. Octopus is a common seafood in people's lives and a seafood product with a relatively large market consumption. Relatively speaking, the breeding market of octopus is still quite promising. The above content is compiled by Bian Xiao for you, I hope it will be helpful to you.

Octopus is a temperate mollusk that lives underwater and is suitable for water temperatures not lower than 7°C. It will die in low salinity environments and is widely distributed in tropical and temperate waters around the world. It is distributed along the north and south coasts of my country. The fishing season is divided into spring and autumn, from March to May in spring and from September to November in autumn.

It can be raised online, by free-range breeding, by feeding bait, or in large ponds. You must pay attention to the choice of species and the temperature. Generally, the water temperature should be around 13°C.

You need to choose an environment suitable for breeding octopuses. The temperature should not be too low and the water should be sufficient. Clean the breeding environment regularly and give the octopus more food nutrition to minimize the risk of octopus getting sick.

There must be a place suitable for octopuses to survive, with sufficient water and suitable temperature. Impurities in the pool must be cleaned regularly to prevent the octopuses from getting sick and dying.
