Problems solved by technology

[0003] At present, single oysters have been cultivated in net cages for sea culture by scallops. However, during the cultivation process of single oysters, the edges of oyster shells are extremely sharp and easy to cut the cages. On the one hand, it causes the loss of single oysters. , reduce the yield per mu of breeding, on the other hand cause the grow-out cage to be damaged, can not be used, increase the cost of breeding, secondly, the breedin...

Embodiment Construction

[0012] In order to better understand the technical solutions of the present invention, the embodiments provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0013] Embodiments of the present invention provide a method for culturing individual oysters in shallow beaches, such as figure 1 As shown, the support 1 made of the cement column with a diameter of 5.0-8.0 cm is first set on the shallow beach. The support 1 is 2.0-3.0 meters long, 1.0-1.5 meters wide, and 0.3-0.6 meters high. Then the polyethylene plastic net of aperture 0.5-2.0 centimeter is made the net bag 2 of long 1.5-2.0 meter, wide 0.5-0.8 meter, height 0.2-0.3 meter, loads on the monomer oyster seedling of 1-2 cm, Sewn the mouth of the net bag, put it in parallel on the cement column support, and put 150,000 to 200,000 seedlings per mu. The aperture size of the net bag 2 is changed regularly according to the size of the individual oysters cultured, an...

Abstract

The invention discloses a device and method for breeding monomeric oysters on a shallow sea shoal. Supporting frames which are made of concrete columns with the diameter ranging from 5.0 cm to 8.0 cm are arranged on the shallow sea shoal at first, and the number of the supporting frames is determined according to the breeding area; the net bags are filled with seed monomeric oysters with the length of 1-2 cm, net bag openings are sewn, and the net bags are placed on the cement column supporting frames in parallel; the seed putting amount per mu is 150,000-200,000, and the hole diameters of the net bags are changed regularly according to the sizes of the bred monomeric oysters. During the breeding period, attachments and the net bags on the flat supporting frames are removed regularly, and breeding is performed for 1.0 year to 1.5 years. According to the device and method for breeding the monomeric oysters on the shallow sea shoal, the monomeric oysters can be directly placed in the net bags and horizontally placed on the cement column supporting frames of the shallow sea shoal, some shoals which are not suitable for breeding the monomeric oysters can also be used for breeding, and therefore the breeding area and the breeding range of the monomeric oysters are enlarged and the shallow sea shoal utilization rate is improved. Meanwhile, the net bags are not damaged by the oysters and can be used repeatedly, cost is low, the loss is little, and the device and method for breeding the monomeric oysters on the shallow sea shoal are suitable for large-area breeding.

Description

technical field [0001] The invention relates to the technical field of individual oyster cultivation, in particular to a device and method for individual oyster cultivation in shallow beaches. Background technique [0002] Individual oysters are oysters that are free and without anchorage. Oysters have the living habit of flocking, and often many oysters are fixed together. Due to the limitation of growth space, the shell shape is extremely irregular, which greatly affects the appearance. The flocking also causes oysters to compete for food and affects their growth rate. Individual oysters are not limited by the growth space due to their free nature, so the shell shape is regular and beautiful, and the size is uniform, which can improve the quality and grade of oysters, so the price is expensive, the benefits are significant, and it is easy to stock and harvest. [0003] At present, single oysters have been cultivated in net cages for sea culture by scallops. However, durin...
