Problems solved by technology

[0004] The current sea cucumber cultivation mainly adopts bottom sowing multiplication and cage culture. Using these methods for sea cucumber cultivation requires special breeding facilities and appliances, which are costly and inconvenient to manage.
In addition, japonicus is a species cultivated in the north, and it often goes into hibernation during the low water temperature period in winter in the north, and its growth stagnates, so the breeding cycle is often longer

Embodiment 1

[0015] 1) Carry out polyculture of stingray and abalone in the sea area of ​​Luoyuan Bay, Lianjiang County, Fujian Province. When the water temperature drops to 21°C, the sundries on the floating raft abalone cages in the sea area should be removed and disinfected.

[0016] 2) Put 30 abalones with a shell length of 5cm and 2 sea cucumbers with a body length of 6cm in an abalone cage with a specification of length×width=0.41m×0.3m, and feed them every 2 days when the water temperature is 16-21°C 1 dry kelp, feed 1 dry kelp every 4 days when the water temperature is 10-16°C.

[0017] 3) After 6 months, count the survival rate of sea cucumber and abalone, and compare with the control group.

[0018] The results showed that the average survival rate of abalone in the experimental group of mixed sea cucumber was 93.3%, and the survival rate of sea cucumber was 99%. The average survival rate of abalone in the control group without sea cucumber was 81%. The economic benefits of bre...

Embodiment 2

[0020] 1) In the Beijiang sea area of ​​Zhangpu County, Fujian Province, the polyculture of stingray and abalone was carried out. When the water temperature dropped to 19°C, the sundries on the floating raft abalone culture cages in the sea area were removed and disinfected.

[0021] 2) Put 30 abalones with a shell length of 6cm and 2 sea cucumbers with a body length of 7cm in a pot-type abalone cage with a diameter of 0.2m. When the water temperature is 16-20°C, feed fresh asparagus once every 2 days Asparagus, when the water temperature is 10-16°C, feed fresh asparagus once every 4 days.

[0022] 3) After 6 months, count the survival rate of sea cucumber and abalone, and compare with the control group.

[0023] The results showed that: the average survival rate of abalone in the experimental group of mixed sea cucumber was 95.5%, and the survival rate of sea cucumber was 100%. The average survival rate of abalone in the control group without sea cucumber was 82.8%. The eco...

Abstract

The invention provides an ecological cultivation method for the mixed cultivation of the stichopus japonicus and the abalone, relates to the abalone, and provides the ecological cultivation method for the mixed cultivation of the stichopus japonicus and the abalone. The method comprises the steps of: removing the sundries on an abalone cultivating container, and sterilizing the abalone cultivating container when the water temperature of the south sea area is reduced at 19-21 DEG C in autumn annually; putting the stichopus japonicus seeds into the sterilized abalone cultivating container; and feeding the forage for the mixed cultivation of the stichopus japonicus and the abalone. Due to the mixed cultivation of the stichopus japonicus and the abalone, the self cleaning capability of the cultivation water body is furthest enhanced, and the environment condition of the cultivation water body is effectively improved. The stichopus japonicus can largely ingest the residual bait and the excrement generated by the abalone, so that the water body pollution is reduced, the reproduction and the propagation of the pathogene are reduced, and the disease infection of the abalone is reduced. As the stichopus japonicus belongs to the mixed cultivation, the extra cultivation cost does not need to be added, and the cultivation benefit is higher.

Description

technical field [0001] The invention relates to abalone, in particular to an ecological breeding method in which species of thorns participate in the mixed culture of abalone. Background technique [0002] Abalone is a kind of precious sea treasure, known as the first of the eight seafood treasures. As a tonic with high nutritional value and a good food therapy product for regulating human physiological functions, abalone is known as "soft gold". With the growing demand for abalone in domestic and foreign markets, the abalone aquaculture industry has developed rapidly, especially in the southern sea area of ​​my country, the abalone aquaculture industry has developed rapidly. However, the existing traditional abalone aquaculture industry is limited by the aquaculture technology and aquaculture model, the aquaculture ecological environment is deteriorating day by day, and the aquaculture output is stagnant, resulting in a substantial decline in economic benefits. [0003] C...
