Stocking density is very important. What is the reasonable density for octopus farming?

Octopus is a freshwater fish with eight whiskers and black hair. Its meat is tender and nutritious, making it suitable for people with weak constitution and malnutrition. It only takes one year for artificial breeding to reach 4 catties, and it has the characteristics of fast growth and easy reproduction. Octopus has strong adaptability to the environment, and the most suitable temperature for growth is 20~25℃. In terms of temperature, octopus is not very suitable for breeding in the Northeast. However, there is a kind of octopus in Heilongjiang that is not only large in size, but also grows fast. It can resist low temperature and low oxygen, and can grow in very harsh environments.

As octopuses grow in weight, they consume a lot of oxygen, so it is necessary to increase oxygen in the breeding pond. This can be achieved by installing an oxygen delivery pipe in the middle of the pond to ensure that oxygen is added when needed. Catfish feeding. When the fry are released, the fry need to be fed with an appropriate amount of feed. When the fry are slightly larger, they need to be raised separately. After a month, catfish can be fed with animal offal, such as duck intestines, chicken intestines, duck lungs, chicken lungs, etc. Disease prevention and control of octopuses. Octopus diseases include black body disease, enteritis, bubble disease, etc. These diseases should be prevented in advance.

Generally, no more than 1,000 fish can be raised in one acre of fish pond. But it also depends on the species, such as grass carp. There are 400-600 grass carp and 200 silver carp in one acre of grass carp. There are 50 carps. Grass carp can be fed with granular feed, not too densely. Stocking large-sized fish is a high-yield measure for pond fish farming. Large-sized fish have the characteristics of strong disease resistance, high survival rate, and rapid growth. Because of the octopus, it can eat some small fish, but when cleaning the reservoir, it needs to be cleaned with other fish. You can't put half of the other fry in. If you put it, it will be eaten by catfish. It is recommended that you raise some low-priced economic fish first, slowly explore, and after you have some experience, depending on your local geography and water quality, raise some high-end fish.

The number of fish in a general fish pond should not exceed 1,000, because this can ensure the life safety of the octopus, allow the octopus to grow better, and also ensure the quality of the octopus meat. Therefore, when we raise octopuses, we must pay attention to this issue.

This depends on the breeding site, size, and environmental waters, but octopuses have a very strong ability to adapt to the environment, and the density can be adjusted based on subsequent observations.

In the process of octopus farming, the density of fish farming is very important, so you need to choose the appropriate density according to the size and shape of your pond.

How to raise octopus?

Octopus, also known as octopus, can be cultured in cages. The mesh is smaller than the fish species, and a net cover is needed to prevent the octopus from escaping. Octopus is mostly cultured in harbors with calm waves. The suitable water temperature is 15-23℃. Generally, it is mostly cultured in spring and summer (June and July) and autumn (October-December).

Octopus fry caught in cages are most suitable, but those caught from bottom trolling nets can also be used. The amount of fry to be released varies depending on the water temperature and water flow. Large cages can be used to release 36-42 kg of fry per cubic meter, while small cages can be used to release 25-30 kg of fry per cubic meter.

To prevent the seedlings from killing each other, the same batch of seedlings should be released, and the seedlings should be put into the cage after they are full.

Reproduction characteristics

Octopuses are ferocious and cruel to their "enemies", but are very loving and considerate to their own children, even willing to die of exhaustion.

Female octopuses give birth only once in their lifetime, laying hundreds to thousands of eggs (smaller ones have fewer eggs, and smaller ones have more), which they hide in their caves and hatch during the incubation period (different species take different times, 4-6 weeks);

The female octopus guards the cave closely, not eating or sleeping, not only to drive away predators, but also to keep waving its tentacles to keep the water in the cave updated so that the unhatched babies can get enough oxygen. On the day the baby octopus hatches, the mother octopus has completed her life's work and dies of exhaustion.
