What kind of food should be used when feeding abalone?

Feeding and management For abalone fry that have just been put into the breeding area, seaweed is the main food. Abalone fry can be fed with baits such as Ulva pertusa, and artificial bait should be fed at the same time. In the three seasons from September to November, seaweed bait is generally scarce, and artificial bait is mainly used at this time. At the same time, dried kelp can be fully soaked and crushed, and then fed to abalone. If seaweed is used as the main bait during the feeding process, the amount of bait fed should be appropriately increased to ensure that the abalone has enough bait to eat. Generally, abalone fry are fed once every 4-6 days, and the amount of bait fed is based on 90-120% of the total amount of abalone, and the residual bait is controlled between 15%-20%. In the process of abalone feeding and management, whether the bait is put in scientifically and whether the feeding amount is sufficient are the key factors that determine the growth rate and survival rate of abalone.

Practical experience shows that ensuring the freshness of bait is of great help in promoting the healthy growth of abalone. Fresh bait can ensure the quality of abalone's feeding, thereby better improving the disease resistance of abalone and improving the survival quality of seedlings. In the specific feeding process, the amount of bait fed should be scientifically adjusted according to the size of abalone individuals and the temperature of seawater. Daily management In daily management, cages, wooden branches, root ropes, hanging ropes, floats and pendants should be checked regularly. If rope entanglement is found, it should be solved in time, and various abalone farming facilities should be checked in detail to see if they are firm. Shellfish floating mud and miscellaneous algae on the cage wall or in the cage should be removed at any time, especially oysters, mussels, barnacles, sea squirts, bryozoans and anemones fixed on the abalone shells. Most of these harmful organisms can be fixed on the cages and abalone shells, resulting in a decrease in the water permeability of the abalone cage, affecting the movement and growth of abalone, making it difficult for abalone to eat, become thin, and die.

The main measures against these harmful organisms are prevention and manual removal. Prevention is to avoid their heyday of attachment based on the understanding of their reproduction rules, and it can also be prevented by drug coating. Manual removal is to use a glue stick to gently tap the miscellaneous algae and shellfish on the abalone cage. The glue stick does not damage the net cage, and a small shovel is used to clean up the remaining shellfish that are fixed on the abalone shell and cannot be knocked out. In addition, the floating mud in the cage should be suddenly flushed after each sea trip to prevent the floating mud from clogging and causing death. Abalone likes to live in rocky waters with clear seawater, turbulent water, and algae, and feeds on algae and plankton. Farmed abalone eats brown or red algae, kelp, seaweed, etc.

Abalone breeding feed Abalone artificial compound feed mainly has three forms: granular and micro-granular feed, mainly used to feed young and juvenile abalone; powdered feed is mainly used to feed young and juvenile abalone; and flake feed is mainly used to feed adult abalone. The flake compound feed is about 1 mm thick. The length of the long flake is 12~14 mm and the width is 8~10 mm; the diameter of the round flake is about 8~12 mm. According to the research on abalone feeding ecology, abalone compound feed also has oblate plates. Its specifications include small abalone with a diameter of 6-8mm and a thickness of 1.2mm, which is fed from the corrugated plate peeling stage to the shell length of 10mm and juvenile abalone with a diameter of 9-12mm and a thickness of 1.4mm, which is fed to juvenile abalone with a shell length of more than 10mm. Abalone compound feed is mainly used in the early stage of abalone, mainly before the abalone grows to 2 cm. Once it is put into the cage, it is mainly fed with natural bait. Its raw materials include fish meal, soybean meal, active millet, wheat flour, seaweed powder, vitamins and minerals, etc. Its protein content exceeds 30%.

Its raw materials include: fish meal, soybean meal, active rice, wheat flour, seaweed powder, vitamins and minerals, etc. Its protein content is more than 30%.

Abalone likes to live in rocky reefs with clear water, fast currents and dense seaweed, and feeds on seaweed and plankton. Artificially cultivated abalone eats brown or red algae, kelp, sargassum, etc. During the growing season in June, July, August and September, they eat kelp.

Abalone should be fed according to its growth period. Abalone generally feeds mainly on seaweed and plankton, and occasionally eats some kelp.

Is it difficult to farm abalone? What are the requirements for farming technology?

Abalone farming is actually not difficult. The key is to adopt the correct method and put it into action, constantly summarize and improve in practice. There are indeed certain requirements for farming technology. Below I will list some issues that need attention.

1. Feeding should be scientific and reasonable

For abalone that has just been put into breeding, it should be combined with the actual needs of aquaculture, and asparagus and other feeds can be added. At the same time, mixed artificial baits can also be used. From September to November, seaweed bait is usually very scarce. It is mainly artificial fish bait. Before feeding abalone, the dried kelp can be thoroughly soaked and crushed. During the feeding process, if laver is the staple food, the feeding amount should be appropriately increased to ensure that the abalone has enough bait. Abalone fry are usually fed once every 4-6 days. The amount of bait is 90~120% of the total amount of abalone, and the remaining amount is controlled at 15%~20%. In the process of abalone breeding and management, whether the bait is scientifically sufficient is the key factor in determining the growth rate and survival rate of abalone. Ensuring the freshness of the bait is conducive to the healthy growth of abalone, and fresh bait can ensure the feeding quality of abalone, thereby better improving the disease resistance of abalone and the quality of life of seedlings. In the specific feeding process, the feeding amount should be scientifically adjusted according to the individual size of abalone and the temperature of seawater.

2. Conduct safety monitoring regularly

During the abalone breeding and management process, a dedicated person should be responsible for abalone safety monitoring and water quality testing. Feed every day, and check the cage regularly and irregularly to see if it is firm and leaky. Ensure that the cage will not be damaged or worn during the breeding process of abalone, and repair it in time if there is a problem. At the same time, the growth of abalone seedlings should be monitored to avoid escape from damaged parts to ensure the breeding benefits. During the typhoon season, the safety protection of the cage should be strengthened to reduce the risk of breeding. In addition, water quality monitoring should be carried out in daily work, the color and quality of the water should be checked frequently, the drainage layer in the cage should be adjusted according to seasonal changes, the pH value of the water should be adjusted appropriately, and shade should be provided in summer.

3. Ensure the cleanliness of the breeding environment

After the cage is fixed in the seawater for a period of time, it should be cleaned regularly. Generally speaking, the time is on low tide days. The cleaning process mainly includes the following aspects: First, timely remove the algae and attached organisms in the cage to ensure smooth water flow in the cage and continuously provide clean water for the growth of abalone; secondly, timely remove the bait, organic impurities, fermentation products, sediments and other substances remaining in the cage. When cleaning, it is necessary to ensure that the integrity of the cage is maintained, and if there is any damage, it should be repaired in time; finally, the fish and shrimp larvae should be cleaned in time. The growth of caged fish and shrimp fry will seriously threaten the healthy growth of abalone. When cleaning the cage, lift the cage and abalone from the water, then transfer the abalone to another prepared cage and clean the cage with seawater.

The above are the issues that need to be paid attention to during abalone farming. They are provided for your understanding, study and reference. I hope they will be helpful to you.

It is quite difficult to breed them. There are very strict requirements for breeding technology, and you need to learn very professional and scientific breeding technology, so that you can improve the survival rate while also increasing the yield, and you can have very good economic benefits.

Breeding is really difficult. It has very high requirements for breeding technology and good water quality. A series of problems will arise during the breeding process, so you must be prepared.

Abalone farming is very difficult. It requires a professional site, professional temperature, professional water source, specific farming methods, and a special environment.

Breeding is particularly difficult and has very strict requirements on breeding technology. There must be sufficient temperature, reaching around 20°C. It is also necessary to ensure that the water inside is particularly clean and no impurities are added to it.
