Comparing with other shellfish, the cultivation of the square spotted snail has the following advantages:

One is that the source of snail seedling is guaranteed, and the quality of snail seedling is reliable.

The second is that the seedling is capable of adapting to the habitat environment, and it is easy to grow. The suitable growing water temperature of Fangbang Dongfeng snail is 24℃~33℃, the specific gravity of seawater is 1.016~1.023, and the pH is 7.3~8.5 (April~October of each year is the season of Fangbang Dongfeng snail cultivation in Hainan Province). During the rearing period, the snail seedlings have fewer diseases, and the chance of successful breeding is high, and the survival rate of breeding is 80% to 90%, and the highest can reach 95%.

Thirdly, the growth rate of snail seedlings is fast, the breeding cycle is short, and the yield is high. Stocking specifications for 0.8 cm to 1 cm of snail seedlings, stocking density of 700 to 1,000 grains per square meter, after 6 months to 7 months of feeding, adult snails can reach 100 grains per kg to 140 grains of commercial specifications, the general output of 5 kg per square meter to 7 kg, high up to 8 kg per square meter to 8.5 kg.

Fourth, low production costs, good economic efficiency, input-output ratio. The cost of producing each kilogram of adult snails are: about 36 yuan to 40 yuan to raise their own seedlings; purchase of snail seedlings to raise about 60 yuan to 70 yuan (specifications for the 0.8 cm to 1 cm snail seedling for 0.2 yuan per grain), the feed coefficient of 4 to 6, the market price of 120 yuan to 140 yuan per kilogram ranging from each square meter of profit of about 80 yuan to 90 yuan, the ratio of input to output for 1:1.5 to 2.

This is the first time that I've seen the snail seedlings in the market, but I think it's a good idea.

Fifth, the production equipment is simple, less investment, small risk, daily feeding management technology is not difficult, simple operation.

As early as in the second half of 2005, Hainan Province, coastal cities and counties set off a square spot East wind snail farming production boom. In recent years, Hainan Province, shrimp production due to disease and shrimp prices fell and slipped into the doldrums of the status quo, Hainan Provincial Oceanic and Fisheries Department last year to vigorously promote the development of the square spot east wind snail aquaculture production. Now, Hainan Province, the total stocking of square spot east wind snail water body has rapidly expanded to 60,000 cubic meters, with a total output of 302 tons, the total output value of nearly 40 million yuan
