Technical Field
The invention belongs to the technical field of giant clam and coral culture, and particularly relates to a giant clam and coral land-based culture system and a mixed culture method of two organisms.
Background
The coral reef ecosystem is an ecosystem with the highest biodiversity and productivity in the ocean and is known as a tropical rainforest in the ocean. The organisms of the coral reef ecosystem can be divided into reef-building organisms and reef-attaching organisms, wherein tridacna and reef-building coral can continuously accumulate calcium carbonate and are the most important two reef-building organism groups in the ecosystem. In recent years, due to the influence of global warming, seawater acidification, human activities and the like, the biomass of tridacna and hermatypic coral is sharply reduced, and various rare tridacna and coral are even endangered to be extinct. In order to protect giant clams and corals and restore species diversity of coral reef ecosystem, domestic and foreign researchers have taken various measures to protect giant clams and coral resources. The artificial breeding and the living body germplasm library construction are one of effective methods for protecting giant clams and coral germplasm resources, and the establishment of feasible giant clams and coral land-based culture technology is the premise for carrying out the work. At present, there are mainly 2 kinds of giant clam and coral culture modes at home and abroad: firstly, erecting a light source with certain illumination intensity for temporary rearing on the basis of a traditional economic aquatic animal seedling raising workshop or a medium and small glass display jar; secondly, a sunshade net is erected on the top of the open-air cultivation cement pond or the glass fiber reinforced plastic seedling raising pond for cultivation. However, in the actual culture process, the first culture method influences the normal growth of tridacna and coral due to the large difference between the artificial light source and the natural light spectrum, insufficient illumination of the artificial light source and other defects; the latter is very susceptible to severe weather such as typhoon and rainstorm, and the cultivation controllability is very poor. Therefore, it is necessary to design a culture system special for giant clams and corals according to the ecological habits of giant clams and corals and establish a matched culture method.
