Problems solved by technology

Because the oyster seedlings of this method have a relatively high attachment density on the attachment base, the attachment density is also too large during sea culture, and the growth space squeezes each other. The mature individuals are often not large,...

Abstract

The invention provides a culture method of cultchless oysters. The method includes the steps of primary spatfall culture, wherein first plastic sheet substrata with roughened surfaces are hung in an oyster spat pool, it is guranateed that the plastic sheet substrata are immersed in water of the oyster spat pool, a sunshade net is additionally arranged over the oyster spat pool, and primary spatfall culture is carried out; secondary spatfall culture, wherein the first plastic sheet substrata obtained after primary spatfall culture are taken out of the pool, oyster spats adhering to the first plastic sheet substrata are sheared off one by one along the edges and then adhere to adherence points of second plastic sheet substrata, each second plastic sheet substratum is of a black plastic square mesh structure with the four corners provided with through holes, each mesh is provided with four adherence points, every 10 second plastic sheet substrata to which oyster spats adhere are strung together with ropes in a vertical stringing mode to form a substratum string, a weight is hung at the lowermost portion of each substratum string to prevent the substrata from floating or twining underthe action of water flow, and the substrata are hung in seawater for secondary spatfall culture.

Description

technical field [0001] The invention belongs to the technical field of oyster cultivation, and in particular relates to a method for cultivating single oysters. Background technique [0002] Oysters belong to the mollusc phylum and are the most common bivalve molluscs in the coastal area. Its meat is delicious and nutritious, and it is known as "milk in the sea". Oysters occupy a very important position in my country's mariculture industry and have a high Economic Value. The existing oyster artificial breeding technology mainly includes: after artificial insemination, the fertilized eggs develop into larvae in the nursery pond, and after the larvae develop to the eye point, hang the attachment base in the nursery pond, and the oyster seedlings attach to the attachment base, and attach The base mostly uses oyster shells or scallop shells. After the oyster seedlings are attached to the attachment base, they are cultivated indoors for several days and then transferred to the s...
