Embodiment 1

[0029] A method for artificially raising seedlings of Nidongfeng snails, comprising the following steps:

[0030] Step 1, seedling preparation: Stir the small miscellaneous fish, brown sugar and koji with a mass ratio of 10:1:0.1 evenly, seal and ferment for 25-35 hours to obtain fermented fish paste; boil human urine for 20 minutes to obtain processed human urine; Mix the fermented fish paste and the processed human urine in a plastic bucket evenly at a mass ratio of 2:1 to obtain a fish paste mixture;

[0031] Step 2, larvae cultivation: Fill the larvae cultivation tank with unfiltered seawater, inflate it, apply 10ppm fish paste mixture, and aerate for 3 days. After observing that the water color and the density of microorganisms such as rotifers are suitable, put the newly hatched larvae , when the density of rotifers and algae in the cultivation pond is insufficient, apply 3-5ppm fish slurry mixture every day until the juvenile snails are cultivated;

[0032] Step 3. Cul...

Embodiment 2

[0034] A method for artificial seedling cultivation of Nidongfeng snails is characterized in that it specifically comprises the following steps:

[0035] Step 1, seed snail cultivation: spread 10cm thick medium-coarse sand (fineness modulus at 1.6-3.7) at the bottom of the cement seedling cultivation pond with a size of 8m*2m*1m, and put 50kg of individual hypertrophic and healthy seed snails , add aerated running water, feed fresh and frozen miscellaneous fish or water crabs (crabs that have just shelled or are about to shell) every day, change the water every day, and when the newly added water is 1 / 5 of the volume of the seedling cultivation pool, stop adding water and splash it 2kg white granulated sugar, add convective water (running water cultivation) after 2 hours, and cultivate until the snails mate to produce oocyte sheets;

[0036] Step 2. Seedling preparation: Stir small miscellaneous fish, brown sugar and koji with a mass ratio of 10:1:0.01 evenly, seal and ferment...

Abstract

The invention belongs to the technical field of aquaculture and discloses a method for artificial breeding of babylonia lutosa. The method for artificial breeding includes: preparing fermented fish pulp from small miscellaneous fish, brown sugar and koji, culturing algae and rotifer in natural seawater by the fermented fish pulp and treated human urine to use as initial feed for larvae, feeding with fresh oyster pulp to culture after larvae grow into young babylonia lutosa, classifying, and breeding the young babylonia lutosa into adult babylonia lutosa. The method for artificial breeding of babylonia lutosa has advantages that by providing of bait convenient for the larvae to eat, operation is simpler than that in daily feeding of chlamydomonas, convenience in management, time saving andless prone to causing death of the larvae are realized, the survival rate of the larvae growing into the young babylonia lutosa is effectively increased, shells are dark brown and hard and meat is plump when the larvae growing into the young babylonia lutosa in a later stage, the disease rate in an adult babylonia lutosa breeding stage is far lower than that of adult babylonia lutosa obtained according to a traditional artificial breeding method, and accordingly the yield of adult babylonia lutosa is increased, and economic benefits are increased.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for artificial seedling cultivation of Nidongfeng snails. Background technique [0002] Babylonia lutosa (Babylonia lutosa), belonging to the mollusk phylum, Gastropoda, Antyglossidae, Mollidae, and the genus Dongfeng snail, is distributed in the East my country Sea and South China Sea, inhabits the muddy sea area in the subtidal zone, and lives in the bottom. Life. The shell of Nidongfeng snail is thick and solid, the spiral portion of the shell is conical, and the body spiral is enlarged and yellowish-brown. Its meat is delicious and nutritious, and it is a shellfish with high edible value. However, due to the overfishing before the 1990s and the increase in market demand, wild snails can no longer meet the supply of the market. Artificial breeding and seedling cultivation of snails are particularly important. [0003] At present, the conventional seed...
