Problems solved by technology

However, because the spicy snails gather together in groups to mate and lay eggs in the coastal rock crevices in summer and autumn, but the eggs are prolific in the rock crevices or on the backs of companion shells, and it is difficult to collect them, and the habits of the spicy snails are different from the large number of snails that are currently cultured. It is impossible to directly apply its breeding mode, so that the artificial propagation and seedling breeding of spicy snails have been unable to advance, and it is also not conducive to the protection of its wild germplasm resources.

Embodiment 1

[0036] The artificial breeding method of spicy snails of the present invention specifically comprises the following steps:

[0037] 1) Cultivation of snails: Lay four-legged bricks in the snail cultivation tank, then add seawater with a specific gravity of 1.020 and a pH value of 8.0, then put the snails into them, inflate them into convective water for cultivation, and stock them at a density of 3-3.2kg / m 2 , feed fresh miscellaneous fish pieces after sunset every day, drain the seawater in the pond and rinse once a day, after about 2 months, the snails will mate at night to produce egg slices (egg slices can be produced during the period from ear seed to frost), each egg There are about 300 fertilized eggs on the slice, and the egg slices are collected after sunrise every day. When collecting, carefully scrape the egg slices from the bottom of the pool or the surface of the four-legged bricks with a blade to collect, and estimate the number;

[0038] 2) Incubation: After t...

Embodiment 2

[0044] The artificial breeding method of spicy snail of the present invention may further comprise the steps:

[0045] 1) Cultivation of snails: Lay four-legged bricks in the snail cultivation pool (length 8m×width 2m×height 1m), then add seawater with a specific gravity of 1.020 and a pH value of 8.0, then put 50kg of snails into them, and inflate them to open them Flowing water culture, feeding 3kg of fresh miscellaneous fish pieces after sunset every day, draining the seawater in the pond and washing once a day, after about 2 months, the snails mate at night to produce eggs, each egg has about 300 fertilized eggs, Collect the egg slices after sunrise every day, and carefully scrape the egg slices from the bottom of the pool or the surface of the four-legged bricks with a blade when collecting, and estimate the number;

[0046] 2) Incubation: After the membrane of the eggs becomes thinner and the larvae swim faster, put them into the hatching pool. The hatching pool (length ...

Abstract

The invention discloses an artificial breeding method of thais clavigera and belongs to the technical field of aquaculture. The method includes: selecting adult thais clavigera for seed thais clavigera culture, allowing spawning in an artificial pond, controlling water flow and water quality to complete egg piece hatching, and completing artificial breeding of thais clavigera through standard-thickness cultivation. Growth environment conforming to habits of thais clavigera is provided to enable thais clavigera to spawn in the artificial pond, so that efficiency is higher when compared with collecting egg pieces in natural sea areas; by controlling the water flow and bait feeding, hatching of fertilized eggs and breeding of larva are promoted. The method is simple in step, easy to master and suitable for popularization and application, the problem that natural offspring seeds of thais clavigera are insufficient is made up, the problem that thais clavigera cannot be completely bred artificially at the current stage is solved, breeding benefit of thais clavigera is increased effectively, and germplasm resources of wild thais clavigera are protected effectively.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an artificial breeding method of spicy snails. Background technique [0002] Spicy snail scientific name wart lychee snail (Thais clavigera Kuster), belongs to molluscs, gastropods, anterior subclasses, neogastropods, murex superfamily, genus litchi snails. Because of its spicy taste, it is commonly known as spicy snail. The shells of spicy snails are small, spindle-shaped, hard and thick, usually 2-3cm high, with about 6 spiral layers, and 5 rows of verrucous protrusions. The surface of the shell is gray-green and yellowish-brown, often mixed with white stripes. The inner surface of the shell is yellowish white, and the inside of the outer lip is black and purple. Spicy snail is a wide-temperature and wide-saline species, which is widely distributed in the coastal areas of my country, lives in rocks below the lowest tide line, and mainly feeds on barnacles, bry...
