Embodiment Construction

[0028] The method for picking seedlings of red snail industrialized seedling cultivation of the present invention, concrete process is as follows:

[0029] The seedling picking facilities are made of rough plastic corrugated boards and brackets that fix the corrugated boards. Before the seedling picking facilities are released, oyster spat are attached to the plastic corrugated boards as animal bait during the feeding habits conversion and metamorphosis of the snail larvae. , the density of oyster spat on the plastic corrugated board is 5-20 / cm 2 , The size of oyster spat is 0.5-2.0mm in shell length. When more than 50% of the red snail larvae develop to the late stage of the third helix to the early stage of the fourth helix, put the seedling collection facilities in a multi-plane and three-dimensional layered manner with plastic corrugated plates in the seedling pond, so as to make full use of the water body and make the red snail The larvae attach to the plastic corrugated...

Abstract

The invention relates to factory fry breeding of aquaculture, in particular to a seedling collection facility for rapana venosa factory seed culture and a method, wherein the seedling collection facility consists of a plastic corrugated plate with a rough surface and a support for fixing the plastic corrugated plate, the plastic corrugated plate is fixed in a chute arranged on the support in parallel, and the side surface relative to a chute connecting rod is bundled up a rope which is parallel to the chute connecting rod. Oyster young shellfishes are firstly adhered on the plastic corrugated plate to be used as animal baits during the process of trophic conversion and metamorphosis of rapana venosa larvae before the seedling collection facility is thrown in. When more than 50 percent of the rapana venosa larvae grow between the later stage of three varices and the initial stage of four varices, and the seedling collection facility is thrown into a nursery pond in a mode that the plastic corrugated plate is in a plane stereo hierarchical mode, thereby leading the red screw larvae to be adhered on the plastic corrugated plate adhered with the oyster young shellfishes, completing the process of the trophic conversion and the metamorphosis and doing intermediate breeding of young screws. The seedling collection facility for rapana venosa factory seed culture can lead the rapana venosa larvae to smoothly complete the process of the trophic conversion and the metamorphosis in factory seed culture.

Description

[0001] This application is a divisional application of the Chinese invention patent application. The application date of the original application: October 29, 2010, the application number: 201010538128.5, the name of the invention: a seedling picking facility and method for industrialized seedling cultivation of red snails, disclosed No.: CN101986833A; According to the examiner's comments on the original application, this divisional application is hereby filed. technical field [0002] The invention relates to industrial seedling production of aquaculture, in particular to a seedling collection facility for industrial seedling cultivation of red snails. Background technique [0003] Rapana venosa, commonly known as "tile snail" and "conch snail", belongs to the phylum Molluscs, Gastropoda, Murexidae, and the genus Rupana venosa. The adult shell height can reach 11-12cm. It is distributed in the Bohai Sea and the Yellow Sea of ​​my country. Its feet are particularly fat, deli...
