Problems solved by technology

The raft culture technology mainly uses a long rope as a floating rope, and there are several large floats on the floating rope. Breeding cages are filled with farmed shellfish or ginseng. The main disadvantages of this farming model are: frequent occurrence of diseases in high-temperature seasons, low survival rate of cultured organisms, and poor wind and wave resistance of the structure. The main breeding areas are concentrated in Waters within the 20-meter isobath
Bottom-sowing breeding technology is to directly sow seedlings in the sea area. The seedlings of this breeding mode are very easy to encounter predators, the survival rate is low, and it is difficult to catch back. The labor intensity is high and the replenishment rate is low.

Embodiment 1

[0030] Such as Figure 1-3 The shown bottom-seeding mariculture facilities suitable for muddy bottom sea areas are applied to scallop (chlamys farreri, gulf scallops, scallops, etc.) culture. A certain number of scallop seedlings are respectively placed in the breeding cages supported by the PVC pipe 1, polyethylene rope 4 and netting 3. Before putting the seedlings, the netting 3 is left at the opening 7, and the opening is closed after the seedlings are placed. 7 sutures. After the seedlings are released, the entire bottom-sowing breeding facility is fixed on the seabed by stakes or anchors 2, and ropes 5 are fixed at both ends of the facility. The upper end of the rope 5 is fixed with a floating ball 6, and the floating ball 6 floats on the sea surface, which is convenient for production management and harvesting .

Embodiment 2

[0032] Such as Figure 1-3 The shown bottom-seeding culture facility is applied to sea cucumber culture. Put a certain amount of japonicus seedlings respectively in the breeding cages supported by PVC pipe 1, polyethylene rope 4 and net clothes 3. Before putting the seedlings, the net clothes 3 leave a mouth at the opening 7. After putting the seedlings, place them Opening 7 sutured. After the seedlings are released, the entire bottom-sowing breeding facility is fixed on the seabed by stakes or anchors 2, and ropes 5 are fixed at both ends of the facility. The upper end of the rope 5 is fixed with a floating ball 6, and the floating ball 6 floats on the sea surface, which is convenient for production management and harvesting .

Embodiment 3

[0034] Such as Figure 1-3 The shown bottom-sowing culture facility is applied to the polyculture of shellfish. A certain amount of sea cucumbers and scallops (chlamys scallops, bay scallops, ezo scallops, etc.) seedlings with a suitable matching ratio are respectively placed in the breeding cages supported by PVC pipe 1, polyethylene rope 4 and netting 3, Before putting the seedlings, the net clothing 3 leaves a mouth at the opening 7, and the opening 7 is sewed up after the seedlings are put. After the seedlings are released, the entire bottom-sowing breeding facility is fixed on the seabed by stakes or anchors 2, and ropes 5 are fixed at both ends of the facility. The upper end of the rope 5 is fixed with a floating ball 6, and the floating ball 6 floats on the sea surface, which is convenient for production management and harvesting .

Abstract

The invention relates to a bottom sowing-type mariculture facility which is suitable for the sea area with silt bottom, in particular to a bottom sowing-type raft frame and a net cage for marine bivalve mollusks, sea cucumbers or mixotrophic culture of marine bivalve mollusks and sea cucumbers. The facility is provided with a PVC pipe, a polyethylene rope for fixing the PVC pipe, a webbing, a stake or an anchor for fixing the facilities, a rope fixed on the stake or the anchor, and a fixable floating ball which is connected to the rope and floats on the surface of water; the PVC pipe is fixedon the polyethylene rope in parallel, the polyethylene rope is arranged in parallel, is perpendicular to the PVC pipe, is positioned at the upper side and the lower side of the two terminals of the PVC pipe and forms the structure similar to a 'soft ladder'; the 'soft ladder' is externally covered by the webbing, and a plurality of independent net cages are formed by combining the PVC pipe, the polyethylene rope and the webbing; the two ends of the undrawn 'soft ladder' are fixed at the bottom of the sea by the stake or the anchor respectively, and the floating ball is fixed at the two ends of the 'soft ladder' by the rope. The facility can effectively prevent the enemies and reduce the influence of storm and ocean current, thus being convenient for management and harvest and favorable tothe comprehensive utilization of mariculture area.

Description

Technical field: [0001] The invention relates to a bottom-sowing type mariculture facility suitable for muddy bottom sea areas, in particular to a bottom-sowing type raft frame and a culture cage for the mixed cultivation of seawater bivalve molluscs, sea cucumbers or shellfishes. Background technique: [0002] At present, bivalve molluscs, such as clam scallops, bay scallops, and sea cucumbers, mainly have two farming modes: raft farming and bottom-sowing farming. The raft culture technology mainly uses a long rope as a floating rope, and there are several large floats on the floating rope. Breeding cages are filled with farmed shellfish or ginseng. The main disadvantages of this farming model are: frequent occurrence of diseases in high-temperature seasons, low survival rate of cultured organisms, and poor wind and wave resistance of the structure. The main breeding areas are concentrated in Waters within the 20-meter isobath. Bottom-sowing breeding technology is to dire...
