Embodiment Construction

[0015] The invention discloses a method for cultivating snail snails, comprising the steps of collecting fertilized eggs, hatching, cultivating larvae, cultivating juvenile shellfish, and the like.

[0016] 1. Collection of fertilized eggs

[0017] The attachment base for picking eggs adopts a corrugated plate as the bottom, and then uses the corrugated plate as the side wall to form a drum shape with a diameter of 70-80 cm, and puts stones, adds water, and inflates. Put 3 kg of parent snails in each drum, about 300 snails / m 2 . After about a week, egg bags begin to be produced. The average length of the egg bags is 1.2 cm and the diameter is 0.2 cm. Each parent snail produces an average of 25 egg bags, and there are about 200 to 300 fertilized eggs in each egg bag.

[0018] 2. Incubation

[0019] Natural hatching in the pool, after which the cultivation process is also carried out in seawater at natural temperature.

[0020] 3. Larva cultivation

[0021] At the initial s...

Abstract

The invention provides a Thais bronni breeding method. The Thais bronni breeding method comprises the following steps of: collecting and incubating fertilized eggs; cultivating larvae; and cultivating juvenile mollusks, wherein the fed baits in the pelagic period of larva cultivation comprise chrysophyceae, chlorella, tetraselmis and chaetoceros in a ratio of 10:1:1:1; during metamorphosis period before juvenile mollusk period, the varieties and the amounts of the fed baits, including shrimp slices and razor clam meat, are increased along with time; and the prawn slices and the razor clam meat with a certain ratio are maintained during cultivation of the juvenile mollusks. According to the thais bronni breeding method, different bait constitutions and feeding amounts are provided for successful growth of the thais bronni in each development stage of the thais bronni. Compared with the prior art without artificial breeding, the method establishes the basis of artificial breeding of the thais bronni, so that artificial culture of the thais bronni can meet the requirements of the market.

Description

technical field [0001] The invention relates to a method for growing seedlings of snails. Background technique [0002] Thais bronni, commonly known as yellow snail, belongs to benthic gastropod shellfish. The shellfish has high economic value, delicious meat and rich nutrition, and is widely favored by the public. It is a special product of Shengsi. The first-class raw material of "pulp". The soft body of snails can lower blood pressure and cure cholecystitis, and the shell can heal skin diseases. However, due to the vast market of snails, its harvesting intensity has also increased year by year. With the increase of people's consumption of snails, the resources of this species have decreased sharply, their specifications have decreased, and their quality has declined. In view of the current situation of the contradiction between the resources of snails and the market supply and demand, it is very necessary and urgent to supplement the seed resources of snails in natural ...
