Description
Technical Field
The invention belongs to the field of marine organism cultivation equipment, and particularly relates to a zooplankton cultivation circulating system with a bionic jellyfish structure.
Background
Jellyfishes are zooplankton of middle and lower levels of marine life, and are popular among people due to various morphological characteristics and changeable swimming postures, so that the jellyfishes are breeding species with high commercial value in aquatic breeding. However, the jellyfishes known to people at present are mainly large-sized pot jellyfishes, the pectinate jellyfishes are rarely known, and the individual small spherical lateral wrist jellyfishes are less known. In recent years, scientists have further understood the biology and ecology of the spherical lateral carpal jellyfish and have deeply known the special body structure of the spherical lateral carpal jellyfish, but research on bionic and aquatic breeding of the jellyfish is very little. The spherical lateral wrist jellyfish is less than 2cm, no swimming organ exists, the rotation of the body is mainly pushed by the movement of the comb hair plate outside the body, the comb hair plate can emit blue and white light at night, and the craving can be carried out by a tentacle which can extend for tens of times beyond the body. The spherical lateral carpal jellyfish does not have finely divided internal body organs, and the ingested food is led to all parts of the body through the gastric circulation cavity, enters the main and auxiliary water pipes from the mouth end and the 8 auxiliary water pipes which are uniformly distributed on the whole body. This particular mechanism of body movement is not available to other organisms.
At present, the existing zooplankton breeding devices at home and abroad are mainly concentrated on breeding devices of jellyfishes, and a small number of devices are specially used for common zooplankton-copepods. At present, the domestic jellyfish breeding device can meet the breeding requirements of the hydroids and the dishes of large-scale jellyfish-bowl jellyfish, but the applicability of the breeding device is poor due to the lack of understanding of the ecological characteristics of different zooplankton. The existing culture device for the pot jellyfishes, particularly the culture device for the attachment of hydranth, cannot be used for culturing other types of jellyfishes such as small-sized jellyfishes. The ctenocephalides are large zooplankton in zooplankton, have important ecological value and are key species for linking small and medium zooplankton and fish. In addition, in recent years, the large-scale aggregation of the species brings safety threat to cold source water intake of nuclear power plants, so scientists need to perform deep biological and ecological research on the species. The existing research shows that the pectinate jellyfish is a colloid organism different from the large-scale pot jellyfish, the life history characteristics, the movement mode and the reproduction mode of the pectinate jellyfish are different from those of the large-scale pot jellyfish, the pectinate jellyfish has no hydroid stage, the appearance characteristics are different from those of the common umbrella jellyfish, the swimming mode is also special, the pectinate jellyfish swims and rotates through eight rows of longitudinal pectinate plates of the body, the elongated tentacle can exceed the body by times, the swimming postures are beautiful and various, but the pectinate jellyfish is small in shape and difficult to observe and is not well known by the public, and the development aiming at the ornamental value of the pectinate jellyfish is still needed to be improved.
Based on the current situation that the current large-scale zooplankton including the ctenopharyngodon outbreak affects the nuclear power station, the attention of the public to the marine ecological environment and the ornamental love to the spherical lateral wrist jellyfish are combined, a culture device which has wide applicability and is suitable for zooplankton with weak swimming capability needs to be designed, and the display characteristics of the ctenophythora are highlighted.
