Description

Chinese horseshoe crab larvae simulated ecological breeding device

Technical field

The invention relates to a Chinese horseshoe crab breeding technology, and in particular to an ecologically simulated breeding device for Chinese horseshoe crab larvae.

Background technique

Chinese horseshoe crab (Tachypleus tridentatus), also known as Chinese horseshoe crab, Oriental horseshoe crab, three-spined horseshoe crab, and couple fish, belongs to the phylum Arthropoda, the subphylum Chelicera, the class Limulus, the order Xiphophoridae, and the family Limulus. Its earliest fossils can be traced back to the Cambrian period. (about 485 million years ago), it is one of the few marine living fossils on earth. The Chinese horseshoe crab has shown a population decline trend in its distribution area, and was defined as an endangered species by the "Red List of Chinese Species" in 2004. Chinese horseshoe crab is an indicator species of estuarine ecosystem, which can reflect the overall health and stability of coastal wetland ecology. The amoebocyte extract from the blue blood of the Chinese horseshoe crab can be made into Limulus reagent, which can sensitively detect trace amounts of bacterial endotoxins and fungal polysaccharides. It is currently widely used in clinical medicine, pharmaceutical and food industry and other fields. Replenishing the population in the natural environment through artificial nursery and multiplication and release is an important ex-situ conservation measure to restore horseshoe crab resources in China. At present, the proliferation and release of horseshoe crabs in China are mainly 1-year-old larvae, but Carmichael et al. (2003) found that the mortality rate of 6-year-old or above juvenile horseshoe crabs in their natural environment is significantly lower than that of 1-5-year-old larvae, and the proliferation and release of 6-year-old or above larvae is more It can ensure the effectiveness of scientific discharge. In addition, many studies of Chinese horseshoe crab biology rely on long-term laboratory observations. Therefore, the breeding technology and equipment of Chinese horseshoe crab larvae need to be improved urgently.

Most of the traditional Chinese horseshoe crab larvae breeding devices are containers or cement tanks with a single structure. The bottom of the tank is covered with sea sand or coral sand. Since the water in traditional breeding devices or feeding tanks does not flow, feeding high-protein feed can easily cause water quality to deteriorate. Therefore, The sea water needs to be changed once a day, and the water changing operation process is complicated and the cost of maintaining water quality is high. In addition, the water changing process will not only easily cause damage and interference to the young horseshoe crabs, but also cause the water ecological environment to be unstable. Therefore, the young horseshoe crabs Horseshoe crab survival rate is low.
