Method for artificial propagation of mytilus coruscus in intertidal zone of rocky reef phase
A technology for thick-shelled mussels and intertidal zones, applied in fish farming, application, climate change adaptation, etc., can solve the problem that the time for complete fixation is more than 12 hours, and the time for flooding and flooding is generally less than 3 hours. Proliferation of thick-shelled mussels is not, being swept away by sea water and other problems, to achieve the effect of increasing the natural attachment rate, reducing artificial labor, and improving the survival rate

Embodiment 1
[0027] The materials used in this embodiment include: thick-shelled mussel spat (average shell height 1.55cm) 6000 grains, papyrus mesh cloth 15m, thick hemp rope (more than 20mm in diameter) 17m, fine hemp rope (diameter 1mm) Several, some hemp ropes for connection, 4 mesh bags;
[0028] A method for artificially multiplying thick-shelled mussels in the intertidal zone of rocky reef facies, comprising the following steps:
[0029] (1) Cut the papyrus mesh into rectangular mesh pieces with a width of 25cm and a length of 3m; soak the coarse hemp rope (more than 20mm in diameter) and the fine hemp rope in seawater for 48 hours, and cut the coarse hemp rope 5 sections of hemp rope with a length of 3.4m; will be placed in the center of the mesh block, the direction of the hemp rope is the same as the long side of the mesh block, and the two ends of the hemp rope are exposed from the mesh 20cm; Loosely wind several fine hemp ropes on the thick hemp rope section;
[0030] (2) the...
Embodiment 2
[0035] It is basically the same as Example 1, except that the mesh cloth used is made of plastic, and the thick hemp rope used is also made of plastic. After 48 hours of culture, the attachment rate of mussels was counted, and the natural attachment rate was 100%.
Embodiment 3
[0037] Substantially the same as Example 1, the difference is that the mesh cloth used is papyrus, and the thick hemp rope used is a plastic rope with a diameter of more than 20mm. The attachment rate of mussels was counted after 48 hours of increasing cultivation, and the natural attachment rate was 100%.
