Technical field:

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:

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 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 recapture, labor-intensive, and the replenishment rate is low.
