Embodiment 1

[0035] Oyster sinking and floating hanging raft culture method, including:

[0036] A, adopt buoyant material, such as Chinese fir, weave into square floating raft, and arrange at least one polystyrene float 170 on the floating raft, make the buoyancy of all floats 170 greater than the gravity of the floating raft, place the floating raft on the sea surface Finally, because the buoyancy produced by the buoy 170 is greater than the gravity of the floating raft, the floating raft can finally be in a floating state, and then the floating raft is fixed (the fixing method is any one in the prior art, such as fixing by a traction anchor), Make it impossible to drift away or make it drift only in a small range;

[0037] B, hanging raft culture, the hanging mode is any one in the prior art;

[0038] C. 1 to 6 months after raising, sample the weight gain of the floating raft once a month; 7 to 12 months after raising, sample the weight gain of the floating raft twice a month; 13 to 12...

Abstract

The invention discloses an oyster floating raft breeding method, and belongs to the technical field of breeding. The method includes the steps of establishing floating rafts, conducting breeding on the floating rafts, conducting sampling every month after breeding to detect the weight gain of the floating rafts, and increasing the number of floaters each time after the weight gain of the floatingrafts is detected, wherein the sinking depth of the floating raft can be 2.2-2.4 m at 29.8-34.9 DEG C, 3.3-3.5 m at 35-39.9 DEG C, 4.4-4.6 m at 40 DEG C or higher, 2.4-2.6 m at the maximum wind speedlevel of 12-13, 4.5-4.7 m at the maximum wind speed level of 14-15 and 5.4-5.6 m at the maximum wind speed level of 16 or higher. The direct impact of strong light, high heat waves and wind waves canbe avoided, the floating rafts and oysters are effectively protected, the survival rate of the oysters is increased, and high economic benefits are achieved.

Description

technical field [0001] The invention relates to the field of breeding technology. More specifically, the present invention relates to the culture method of oyster sinking and floating type hanging raft. Background technique [0002] The artificial culture of near river oysters has a history of more than 300 years in our country. In the early stage, the breeding methods mainly include throwing stones, tiles, ceramics, and rubber tires in tidal flats (inshore), and in the later stages, they are carried out by inserting bamboo, wood, cement products, etc. Adoption, yield has been greatly improved. In recent years, due to the impact of coastal industries and agricultural sewage discharges, the bottom quality of the offshore sea area has been seriously polluted, and a large number of oyster diseases in the bottom area have broken out, causing heavy losses, and the technology of planting oysters has gradually been eliminated. [0003] Now oyster culture has been developed to use...
