Embodiment 1

[0029] Such as figure 1 and 2 Shown, temporary support protection device of the present invention, comprises the protection net 1 of bottom opening and 4 fixed mounts 2, and protection net 1 is the twisted wire mesh that material is lighter, cubic structure, and the mesh diameter of protection net 1 is 3cm, Slightly smaller than the diameter of the screw body, according to the preliminary investigation of the reef conditions in the bottom sowing sea area, it is pre-made into twisted wire mesh, with a cross-sectional area of ​​2m 2 、4m 2 、8m 2 There are three kinds of specifications altogether, height 2m, 2.5m, 3m altogether three kinds of specifications, and the 8 vertices of protection net 1 are all provided with a fixed rope 11. Because the water flow in the water area in the embodiment is relatively gentle, the fixed frame 2 is made of cheap common steel, including a steel pipe 21 , a fixed ring 22 , a balance plate 23 and steel nails 24 . Steel pipe 21 is long 2-3 mete...

Embodiment 2

[0036]The holding protection device of this embodiment is basically the same as that of Embodiment 1. The difference is that the mesh diameter of the protective net 1 is 0.5cm, which is slightly smaller than the diameter of the screw body. According to the preliminary investigation of the reef conditions in the bottom sowing sea area, it is pre-made into a twisted wire mesh with a cross-sectional area of ​​2m. 2 One specification, three specifications in height 2m, 2.5m, 3m.

[0037] In September 2017, more than 40,000 tower-shaped horseshoe snail seedlings artificially bred at the horseshoe snail seedling base in Leizhou City, Zhanjiang City, Guangdong Province were transported by land to Tanmen Town, Qionghai City, Hainan Province, and then transported to Sansha City by fishing boat Bottom-seeding transplantation experiment near coral reefs. The diameter of the screw body is 0.8-1.5cm.

[0038] After the snails are transported to the vicinity of the coral reef, a layer of ...

Abstract

The invention discloses a temporary culture protection device and a method for bottom sowing transplanting trochus. The temporary culture protection device includes a protection net with a bottom opening and four fixing racks. The protection net is of a cubic structure. Fixing ropes are arranged on the eight vertexes of the protection net. Each fixing rack includes a steel pipe, a balance plate and steel nails which are arranged in a top-to-bottom order. Fixing rings are arranged on the outer sidewall of the two ends of each steel pipe. The protection net is movably fixed to the fixing rings through the fixing ropes. The method for bottom sowing transplanting the trochus includes three steps: fixed point feeding, bottom sowing temporary culture and unprotecting. The device and method of the invention can be applied to seedling bottom sowing of the trochus in the construction of marine pasture, the population recovery of the trochus in the restoration of a coral reef ecosystem and the like, can improve the survival rate of the bottom sowing transplanting of the trochus, and are simple in operation.

Description

Technical field: [0001] The invention belongs to the technical field of marine pastures and resource conservation, and in particular relates to a temporary maintenance protection device and a method for bottom sowing and transplanting horseshoe snails. Background technique: [0002] With the expansion of population and the increasing shortage of land resources, in order to cope with the crisis of food security, human beings are gradually turning to the resource-rich ocean, plowing deep into the blue ocean, and building a "blue granary". However, with the rapid expansion of nearshore fishing and aquaculture, problems such as overfishing and aquaculture pollution have gradually emerged, leading to a sharp decline in offshore marine fishery resources and serious deterioration of the ecological environment in some sea areas. Marine ranching represents the future development trend of fishery and is an important path choice for building a "blue granary". The construction of marin...
