CATDOLL : CATDOLL: Octopus has a good market sales. When is the best time to farm octopus?

1. Octopus has good market sales. When is the best time to farm octopus?

Octopus has a very high egg-laying capacity and a relatively short production cycle, so it is a very good choice for many aquaculture farmers, and its sales in the market are generally very good. Because of this, it is loved by many friends. So when should we start breeding octopus? If you want to breed octopus, you must know something about it. Only in this way can you be more successful in the breeding process. This creature is a temperate mollusk, so it lives underwater and the water temperature cannot be lower than 7℃. So in this case, we need to make choices based on different seawater temperatures.

Generally speaking, the temperature is similar in spring and autumn, so there is no problem at all in breeding during this time, and you can also get very good returns. So if you want to breed this kind of aquatic creature, you must pay attention to the time. This will not only improve our breeding efficiency, but also be of great help to our profit increase.

Now that we have the above understanding, many friends will have a clearer understanding of this situation. In this case, it can be of great help to our breeding and can also help to improve our income level.

In order to be able to obtain more profits, we must pay attention to learning relevant knowledge during the breeding process, so that we can be more handy in the breeding process and avoid losses. If we do not have enough understanding of the breeding of aquatic creatures and easily start to get involved, then the risk is relatively large. I believe that such a situation is not something that any friend wants to see. Only by avoiding these risks can we continuously improve our income level.

Octopus is best cultivated in spring and autumn because the temperature in these two seasons is conducive to the growth of octopus.

2. What is the difference between long-legged octopus and mini octopus?

First, the common names of long-legged octopus and mini octopus are different. Long-legged octopus is commonly known as long-clawed octopus, sow octopus, long-legged octopus, and true octopus. Mini octopus is commonly known as short-clawed octopus and tide-watching octopus.

Second, the appearance of the long-legged octopus and the mini octopus is different. The long-legged octopus is relatively large, with the largest weight reaching 10kg and the arm length being about 20 to 33 cm. The mini octopus looks similar to the ordinary octopus, but is smaller, with the largest being no more than 30 cm.

Third, the distribution of long-legged octopus and mini octopus is different. Long-legged octopus is the most widely distributed among shallow-water cephalopods, widely distributed in tropical and temperate waters of all oceans in the world (except the Antarctic and Arctic waters). Mini octopus is distributed in the coastal waters of the northwest Pacific Ocean. It is a small octopus living in shallow waters, burrowing in mud holes on the beach, and is often caught and eaten in large quantities.

Additional information:

Octopus meat is delicious and can be eaten fresh or dried into octopus. Among them, the dried octopus made from long-legged octopus is of the best quality and is listed as a seafood delicacy in Guangdong, Guangxi and other places. Long-legged octopus is a very important and popular species in the aquatic market, and is also the most common.

The hibernating short-legged octopus can accurately predict when the tide is coming in, hence the name "Watching the tide while watching the clothes". When the tide comes in, it will attack the small crabs and mantis shrimps that have washed ashore. There is a proverb that goes, "A big head watching the tide has eight legs, and an eighteen-year-old cannot catch up. Stand in the cave and watch the tide, and don't stop when the crabs and shrimps are sent to you."

3. The breeding cycle affects the benefits. How long is the breeding cycle of octopus?

The breeding time of octopuses in the ocean is generally concentrated in spring and autumn, when the sea water temperature is around 16°C. Octopuses like to lay eggs in snail shells, so they can be caught by pulling a rope through the red snail shell and sinking to the bottom of the sea. In autumn and winter, they often dig holes in deep-sea sediments. Octopuses are unisexual. The male body has a specialized wrist, called a stalk wrist or joint wrist, which is used to place the spermatophore directly into the external cavity of the female body. Every breeding season, female octopuses lay eggs, which are about 0.3 cm (1/8 inch) long, with a total of more than 100,000, under rocks or in caves. When hatching, the female guards the eggs, cleans them with a sucker, and stirs them with water. Female octopuses need to hatch 4 to 8 weeks after a single spawning. The shape of the baby octopus is similar to that of the adult octopus, but it is very small. After hatching, it needs to drift with plankton for several weeks and then sink to the bottom of the water to hide.

The market supply of wild octopus is generally from January to May each year. If it is industrialized, it only takes about half a year from seedling cultivation to listing, and the market potential is huge. Zhang Hao, the head of Yujiaxin Aquatic Development Co., Ltd., said that in order to shorten the cycle of new varieties entering industrialization, we broke the routine in project implementation and increased the test tolerance environment and feed conversion, which not only promoted the progress of the project, but also improved the scientific and technological content of the project, laying a solid foundation for accelerating industrial breeding. After listening to the report and on-site verification, the expert group composed of Huaihai Institute of Technology and Lianyungang Ocean and Fisheries Bureau unanimously agreed that the short octopus seedlings grew well, had normal body color, and strong vitality, which played an important role in promoting the industrial breeding of short octopus.

Ganyu District has continuously increased its exploration and research efforts in the development of new aquatic products, based on the characteristics of native species in Haizhou Bay, closely focusing on cutting-edge seed technology, and making every effort to promote the upgrading of fisheries and aquatic products. Relying on the appointment of Professor Zheng Xiaodong of Ocean University of China in Ganyu, the school-enterprise cooperation was strengthened to promote the pilot implementation of the technological achievements of Ocean University of China in Ganyu. Following the successful introduction of squid seed breeding technology, Ganyu Fisheries Science Research Institute once again coordinated and promoted the short octopus seed breeding and breeding technology research project, and achieved important results in stages. After harvesting, octopuses can be easily transported and cooled to keep alive. Select the captured live octopuses and remove damaged and unqualified octopuses. Place the selected octopuses in clean seawater for 0.5-1 hour to remove the silt, mucus and dirt in the sucker through the octopus's own physiological activities.

When it is still not clean, do not use your hands or any tools to remove debris from the fish, drain the dirty water, replace it with clean seawater, and purify it again. When adding water, do not look directly at the octopus, and try not to touch the octopus with your hands or other tools during the whole process. Octopuses caught from the sea can survive after soaking in fresh water for a period of time, while octopuses soaked in fresh water can hardly survive after cooling and dormancy. Put ice cubes in a sanitary plastic bag and put it in seawater to reduce the seawater temperature to near 0℃, and the octopus is dormant. Then put the dormant octopus in a plastic bag, add 20% clean seawater, the water temperature is close to 0℃, fill it with oxygen, and seal it. The volume of oxygen is the same as that of seawater and octopus. Add a 2 cm thick sealed plastic bag to the bottom and periphery of the incubator, put in the packaged octopus, put the flake ice on the top, cover the insulation box lid, and seal it with tape.

Not long, maybe about 4 to 5 months, so farming octopuses is not a good investment option.

Three years, because I once raised an octopus, and after three years it grew bigger and could be eaten.

It only takes about half a year, so it is an industry with great investment prospects, and the return on investment is also very high.
