Description
Technical Field
The invention relates to the technical field of coral larva and broken branch long-distance transportation, in particular to a three-dimensional temporary culture device for coral larva and broken branch long-distance transportation and relay culture.
Background
The most beautiful and motivating coral reef in the beautiful vast sea bottom garden. The south sea island reef solidified by taking the hermatypic coral as the main body is an important guarantee for the ownership of the sea in China, is also a valuable treasure house for marine organism diversity and bioactive substances, and has very important ecological value, economic value and national and local strategic safety value. The recovery practice of the degraded coral reef can be roughly classified into passive recovery or active recovery. Analyzing the passive recovery measures adopted globally, there are deficiencies in coral reef management behavior, failure to determine the correct response to key threats, failure to generate quantifiable returns, and failure to ameliorate long-term damage. Because of the slow growth of hermatypic corals and the slow natural recovery process of coral reefs, it is internationally accepted that coral reef management requires a strategy that changes from passive protection to active recovery.
Research shows that in the coral reef ecosystem restoration engineering, artificially propagated and cultured corals can successfully compete with ecological niches in natural communities for biological competition space, show good health conditions, have no parasites or diseases (development and maintenance under controlled conditions), have high survival rate under natural conditions, can realize annual continuous provenance supply, and avoid causing additional artificial collection pressure on natural coral populations. The artificial propagation and cultivation of the corals are transferred to the restoration sea area from the on-road breeding base or the offshore cultivation area, and finally the bottom sowing transplantation is realized, the problem of long-distance transportation of the corals and relay domestication after the corals reach a new sea area must be solved in the process, and the process is very important for improving the survival rate and the success rate of the coral transportation and the bottom sowing.
Coral has high requirements on physicochemical factors of a culture environment, is sensitive to parameters such as water temperature, illumination, dissolved oxygen and the like, is easy to generate emergency responses such as massive mucus secretion, autolysis, thorn cell release and the like to environmental stimulation, and finally leads to large-area death. These problems are common in coral transportation, and the difficulty and urgency of solving the problems are more prominent particularly in large-scale, high-density transportation. In addition, calcified skeletons of hermatypic corals are not resistant to impact collision, and the corals also have a chemical defense mechanism, so that when other corals nearby are sensed to exist, stinging cells are released to repel and kill the other corals so as to protect the growth space of the corals, and death loss caused by physical collision and space competition can be caused by improper conditions in the transportation and high-density cultivation processes.
Therefore, in the transportation and temporary culture processes, under the condition of fully optimizing and utilizing the three-dimensional space of the water body, the physical buffering and fixing performance of the culture device needs to be fully considered so as to reduce the coral loss rate and improve the survival rate. Most coral reef ecosystem restoration work needs to be carried out on island reefs far away from the coast, in order to reduce artificial pressure on natural reef areas, artificial breeding coral is inevitably needed to carry out ecological restoration work, but at present, relevant facilities or device platforms for coral large-scale transportation and relay cultivation do not exist at home and abroad.
