Taking sea urchins and stichopus japonicus as examples, the yield of 2019 in China is about 171700 tons and 8242 tons respectively, but the sea urchins and the stichopus japonicus still face sharp contradictions of short supply and short demand. The low-efficiency intermediate cultivation of the seedlings is the most serious bottleneck for restricting the industrial development.
For the sea urchin industry, sea urchin seedlings produced by seedling culture in the north need to be cultured by indoor heating in winter. The process has high heating cost, unsatisfactory growth effect of sea urchin seedlings, and low proportion of I-type seedlings (the diameter of the shell is more than 1 cm). For the sea cucumber industry, the industrial culture is carried out after the seedlings are grown in the middle ten days of 5 months every year, the seedlings grow to 1000 + 2000 in 9 months, then the seedlings are moved into a pond net cage for culture, and the seedlings grow to about 200 in 11 months. In winter, a long icing period is needed, and daily operations such as feeding, excrement cleaning and the like cannot be performed, so that the young ginseng grows slowly and the death rate is high. The sea cucumber specification is substantially unchanged in the spring of the next year. During the culture process, the survival rate of the sea urchins has great influence on the yield of the sea urchins, and the survival rate of the sea urchins is extremely low due to large-scale outbreak of sea urchins diseases every year. Workers cannot separate diseased sea urchin corpses from healthy individuals in the daily management process, so that spreading of sea urchin diseases is aggravated. Therefore, it is imperative to explore a new method and a new facility for improving the intermediate culture efficiency of sea urchins and sea cucumbers and reducing the morbidity of sea urchins in daily culture.
The patent applicant proves the possibility of overwintering of the sea urchins in the sea cucumber pond by experiments and develops a bait capable of promoting the sea urchins to eat and grow in a low-temperature environment. The method lays a series of technical foundations for intermediate cultivation of sea cucumber rings of sea urchins in winter, but lacks research and development of corresponding cultivation facilities. On the other hand, many studies show that sea urchin excrement is a high-energy and high-nutrient substance, and the effect of using the sea urchin excrement to cultivate shrimps, copepods and scallops is good. Preliminary experiments of the patent applicant also show that the sea cucumber has higher palatability, preference and food intake to the sea urchin excrement, which all provide feasibility for breeding the stichopus japonicus by utilizing the sea urchin excrement. Therefore, a simple and efficient device for ecologically intercropping sea urchins and stichopus japonicus is designed and provided. On one hand, the intermediate breeding process of the intermediate strongylocentrotus intermedius is optimized, a large amount of heating cost is saved, and the production proportion of I-type seedlings is improved; on the other hand, the problems that young sea cucumbers in the sea cucumber pond have no bait, grow slowly, have high mortality and the like in winter are solved, and culture equipment is provided for a subsequent intercropping mode.
The device needs to solve the problems in the design process:
for sea urchins: 1) realize the underwater bait casting of the sea urchins in the ice-forming period of the pond in winter. 2) Effectively utilize the water body as far as possible, reduce sea urchin consumption, increase its area of adhering to in order to reduce crowdedly. 3) The sea urchin excrement can uniformly fall in the sea cucumber area, and the sea cucumber at the lower layer can be used as a bait source. 4) Separating and collecting dead sea urchin from healthy individual
For sea cucumbers: 1) the sea cucumber growth efficiency is improved by using the sea urchin excrement. 2) The metabolic wastes are discharged out of the device, so that the water environment in the culture device is ensured to be high in quality.
For the project: 1) the device is simple and easy to operate. 2) The material is easy to obtain, and the production cost is low.
