Abstract

The invention discloses an artificial propagation method of Cereus sinensis. The method comprises the following steps: capturing and selecting Cereus sinensis parents, building parent cultivation facilities, domesticating Cereus sinensis parents, collecting and hatching fertilized eggs, cultivating attached larvae and young Cereus sinensis and breeding Cereus sinensis. The method can domesticate Cereus sinensis which lives in oceans to grow and reproduce in artificial environments, achieves the purpose of artificial propagation of Cereus sinensis, and can promote development of aquaculture and development and utilization of Cereus sinensis.

[0046] Example

[0047] 1. Sea anemone domestication

[0048] (1) The sea anemone that grows in the natural state is harvested. Choose undamaged, complete and vigorous anemones as broodstock;

[0049] (2) Pave 40cm thick fine sand in the water tank, set up aeration and circulating water system in the water tank, inject seawater to 20cm on the sand surface, seawater salinity 20‰~26‰, maintain dissolved oxygen above 5mg/L, pH 7.8~8.6 . The broodstock of the sea anemone is implanted in sand and cultivated at a density of 20 heads/m 2 ~50 head/m 2. When the culture water temperature rises above 14℃, artificially feed the bait, and cut the fish, shrimp and shellfish into 5cm 3 Size feeding.

[0050] 2. Artificial propagation of anemones

[0051] (1) By adjusting the photoperiod, the cultivated Anemone sinensis is sexually mature and naturally laid eggs and fertilized. The fertilized eggs are collected daily by the automatic collection device of fertilized eggs. The fertilized eggs are incubated in the hatching tank, and the hatching density is 5×10 6 Grain/m 3 ~10×10 6 Grain/m 3 , Water temperature 24℃~28℃, salinity 20~26, aerated incubation, water change 50% daily;

[0052] (2) Floating larvae are obtained by hatching the fertilized eggs, and the floating larvae are cultivated in the nursery tank with a cultivation density of 3×10 6 Head/m 3 ~5×10 6 Head/m 3 , Aerated culture, daily water change 50%~100%, feeding with 50um~80um bait. Cultivate until the primordial base of the eight tentacles appears, and put in the seedling attachment device with seedling density 100/m 2 ~500 heads/m 2;

[0053] (3) The attached seedling device with the seedlings is transferred to the young sunflower cultivation pond for cultivation, 8 tentacles ~ 16 tentacles young sunflowers are casted with Artemia nauplii as bait, 16 tentacles ~ 24 tentacles young sunflowers are cast Artemia nauplii and copepods , Artemia adults, mysis shrimp as bait. 24 tentacles ~ 48 tentacles cast mysid shrimp and fish and shrimp meat as bait. The young sea anemone is cultivated to the peeling attachment device with 24 tentacles to 48 tentacles, and moved into the breeding pond as the seed for sea anemone breeding.
