Problems solved by technology

At present, domestic and foreign research on styliceras is mainly focused on basic theoretical research, such as reproductive ecology, cytology, biochemical markers, etc. The research on artificial breeding technology of styliceras is relatively weak
At present, it is generally believed that sandy or muddy sandy soils should be used as the breeding ground for snail farming, but sandy or muddy sandy bottoms are easily polluted by their own excrement and residual bait, causing diseases

Embodiment 1

[0018] Example 1: Use prawn culture ponds to carry out artificial culture of snails. The size of the abalone culture ponds is 8m x 4m in length. Before the snail seedlings are stocked, the culture ponds need to be fully cleaned and disinfected, and deep sea water from clean and pollution-free sea areas should be extracted. Water is used as aquaculture water. Lay plastic corrugated boards on the bottom of the breeding pond as the attachment base for snail seedlings. The stocking density of snail seedlings is: 16,000 snail seedlings with a shell length of 2 cm, and the average stocking density is 500 / m 2 . During the breeding period, the bait was fed every day. The composition and mass ratio of the bait were 60 razor clams, 40 clams, 50 miscellaneous fish, and 10 kelp. The next day, thoroughly clean the bottom of the pool to remove residual bait and excrement. When the snail seedlings grow to about 5cm, sort the snail seedlings in the culture pond, and the final average stocki...

Embodiment 2

[0019] Example 2: Use abalone culture ponds to carry out artificial culture of snails. The size of the abalone culture ponds is 8m long × 3m wide. Before the snail seedlings are stocked, the culture ponds need to be fully cleaned and disinfected, and deep sea water from clean and pollution-free sea areas should be extracted. Water is used as aquaculture water. Cement square bricks are laid on the bottom of the breeding pond as the attachment base for the snail seedlings. The stocking density of the snail seedlings is: 18,000 snail seedlings with a shell length of 1.5 cm, and the average stocking density is 750 / m 2 . During the breeding period, the bait was fed every day. The composition of the bait and its content by mass ratio were 65% of razor clams, 45% of clams, 55% of miscellaneous fish, and 10% of kelp. The next day, thoroughly clean the bottom of the pool to remove residual bait and excrement. When the snail seedlings grow to about 5cm, sort the snail seedlings in the...

Embodiment 3

[0020] Embodiment 3: Utilize the abalone breeding cage on the floating raft type fish raft on the sea to carry out the artificial cultivation of snails. The specifications of the abalone breeding cage are 43cm long × 32cm wide × 10cm high. Before the snail seedlings are stocked, the breeding cage needs to be thoroughly cleaned And disinfection, and select clean and pollution-free sea areas to carry out. Put the snail seedlings directly into the abalone culture cage, and the stocking density of the snail seedlings is: the average stocking density of the snail seedlings with a shell length of 2.5 cm is 600 / m 2 . During the breeding period, the bait was fed every day. The composition and mass ratio of the bait were 50 razor clams, 50 clams, 40 miscellaneous fish, and 10 kelp. Thoroughly clean the breeding cage the next day to remove residual bait and excrement. When the snail seedlings grow to about 5cm, the snail seedlings in the breeding cage are sorted, and the final average...

Abstract

The invention discloses an artificial cultivation method of hemifusus termatamus and relates to shellfish cultivation. The invention provides the artificial cultivation method of hemifusus termatamus, which can effectively reduce cultivation cost and labor intensity, is convenient for daily inspection and has convenient operation and management. The method comprises the following steps: selecting cultivation facilities and water sources; before stocking young hemifusus termatamus, sterilizing, when using a land cultivation pond, laying attaching base at the bottom of the pool for the young hemifusus termatamus to attach, and cleaning the bottom and sucking sewage regularly after stocking the young hemifusus termatamus; after starting to cultivate the young hemifusus termatamus, feeding with bait every day, wherein the bait comprises the following ingredients according to mass ratio: 50-70 of sinonovacula constricta, 30-60 of ruditapes philippinarum, 40-70 of trash fish and 10-30 of laminaria japonica; when cultivating the hemifusus termatamus, cleaning residual bait at the bottom of the pool, on the attaching base or in the cultivation cage every day, when the shell length of the young hemifusus termatamus reaches 1-3cm, the stocking density is 300-600 / m2, when the shell length reaches more than 5cm, carrying out division, and controlling the stocking density of the young hemifusus termatamus to be within 30-60 / m2.

Description

technical field [0001] The invention relates to shellfish culture, in particular to a method for artificially cultivating snails (snails). Background technique [0002] Hemifusus ternatanus Gmelin, commonly known as "Sound Snail", belongs to Mollusca (Mollusca) Gastropoda (Neogastropoda) Neogastropoda (Galeodiae), is a kind of living in the subtidal zone. The precious marine treasures on the muddy seabed with a water depth of 10-70m are mainly distributed in the southeast coast of my country. Its individual is large, the meat is thick and delicious, rich in nutrition, has nourishing effect, and has high economic value. Due to the over-harvesting and the pollution of the coastal environment in recent years, the coastal snail snail resources in my country are increasingly depleted. Therefore, it is of great significance to carry out artificial breeding and breeding of styloceratum. At present, domestic and foreign research on styliceras is mainly focused on basic theoretical ...
