Problems solved by technology

However, the most prominent problem facing the artificial breeding of Chinese horseshoe crabs at present is that the growth rate of Chinese horseshoe crabs is too slow and the sexual maturity cycle is too long under the artificial breeding environment, which brings great difficulties to the breeding and protection of Chinese horseshoe crabs

Embodiment 1

[0038] A kind of recirculating aquaculture system of Chinese horseshoe crab into horseshoe crab, such as figure 1 As shown, it includes culture pond 1 connected by pipelines, microfiltration machine 2 with 100-150 mesh stainless steel screen, low water storage tank 3, water pump 4, biological filter tank I 6, biological filter tank II 7, protein Separator 8, ozone sterilizer 9, ultraviolet sterilizer 10 and high-level reservoir 11;

[0039] The elevated reservoir 11 is connected with the cultivation pond 1 by pipelines, the elevated reservoir 11 and the microfilter 2 are provided with a plurality of parallel breeding ponds, and the biological filter pond 16 is connected with the pneumatic fan 5;

[0040] The water quality monitoring device I is installed in the low-level reservoir 3, and the water quality monitoring device II 12 and the water temperature control device are installed in the high-level reservoir 11. The water quality monitoring device I and the water quality mon...

Embodiment 2

[0046] A kind of breeding method of Chinese horseshoe crab into horseshoe crab, it is basically the same with embodiment 1, and difference is that the height of PVC pipe is 80cm, and the water level that promptly simulates high tide state is 80cm, and final water body flow rate is 0.4m 3 / h. Among them, the sexual maturity cycle of Limulus chinensis is 2 months.

Embodiment 3

[0048] A kind of breeding method of Chinese horseshoe crab into horseshoe crab, it is basically the same as embodiment 1, and difference is that the height of PVC pipe is 70cm, and the water level that promptly simulates high tide state is 70cm, and final water body flow rate is 0.8m 3 / h. Among them, the sexual maturity cycle of Limulus chinensis is 2 months.

Abstract

The invention discloses a method for accelerating adult Tachypleus tridentatus sexual maturity and cultivation system using the method. The method accelerates the adult Tachypleus tridentatus sexual maturity by controlling the water level and water flow of a cultivation pond to simulate the tidal phenomenon of the natural environment. The cultivation system comprises the cultivation pond, a micro-filter, a low-level reservoir, a water pump, a biological filter tank, a protein separator, an ozone sterilizer, an ultraviolet sterilizer and a high-level reservoir which are sequentially connected through pipelines and is characterized in that the high-level reservoir is connected with the cultivation pond through a pipeline; a water quality monitoring device I is mounted on the low-level reservoir, and a water quality monitoring device II and a temperature control device are mounted on the high-level reservoir; coral sand is laid on the bottom of the cultivation pond. The method is few in control conditions, simple to operate and good in effect. The circulating-water cultivation system is capable of avoiding the poor water quality problem of existing cultivation manners, and the problemof appendage abrasion of adult Tachypleus tridentatus during movement in the cement pond is solved by laying the coral sand on the bottom of the cultivation pond.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and relates to a method for accelerating the sexual maturity of Chinese horseshoe crabs and a breeding system using the method, in particular to a method for accelerating the sexual maturity of Chinese horseshoe crabs and a method for simulating the natural environment of Chinese horseshoe crabs. The recirculating aquaculture system of Chinese Limulus adult Limulus Limulus in order to promote its rapid sexual maturity. Background technique [0002] Horseshoe crab, belonging to the phylum Arthropoda, the subphylum Chelicus, Limulus, the order Xiphosura, and the family Limulidae. There are 3 genera and 4 species in existence. They are known as "living fossils". . The current artificial breeding model of Chinese horseshoe crabs in my country is mainly to simulate the wild growth model of horseshoe crabs in cement ponds for artificial breeding, but the carapace and appendages of adult horseshoe ...
