Problems solved by technology

At present, the processing, storage, and hatching of Artemia worm eggs in Nanjing adopt the method of collecting the collected eggs through multi-stage sieves to dry, then air-drying and storing the eggs, adding water and inflating the eggs to hatch. The shelf life of the eggs is short, and the hatching rate of the eggs is low. Extremely out of sync
The fertilization and water breeding technology of Nanjing Artemia multiplication is greatly affected by environmental factors, often due to insufficient feed supply and difficult control of water quality, resulting in low, unstable, or even no yield
Thereby seriously affecting the development and utilization of Nanjing Artemia as live bait

Embodiment 1

[0008] Embodiment 1: The method for multiplying eggs of Artemia Nanjing according to the present invention includes hatching of eggs, artificial proliferation of insect bodies and collection of eggs. Incubation of insect eggs: Take 100g of wet eggs and soak them in NaOH solution for 48 hours, then rinse the eggs with water. Put the treated eggs into a bucket with a capacity of 12 liters, add 9 liters of water, and control the water temperature between 15-20°C. Under the condition of light and uninterrupted inflation, a large number of knotless eggs will be hatched after 48 hours. larvae. Stop aerating and let it stand for a while, the unhatched eggs and egg shells sink rapidly, the nauplii are suspended in the water, and the nauplii are poured out with water. After adding water, the unhatched eggs can continue to be inflated and hatched, and the nauplii are taken every 24 hours. Repeat this for 4-5 days, and the egg hatching rate will reach more than 70%. The remaining unha...

Abstract

The present invention relates to a multiplication method of Nanjing fairy shrimp ova, said method includes the following steps: incubation of fairy shrimp ova, artificial multiplication and collection of fairy shrimp ova.

Description

technical field [0001] The invention relates to a method for multiplying live animal bait in the biological field, in particular to a method for multiplying Artemia nanjing eggs. Background technique [0002] At present, the vast majority of aquatic animal seedlings need to use animal live bait, among which Artemia (sea Artemia) is a widely used animal live bait. With the breakthrough of large-scale artificial breeding technology of famous, special and high-quality new aquatic animals, the fish, shrimp and crab breeding industry is thriving, and the demand for animal live bait is increasing day by day. Due to the dwindling resources of Artemia eggs, it has directly affected the vigorous development of artificial breeding and aquaculture of certain aquatic products. In the freshwater field, zooplankton are used as bait for seed production of some famous freshwater species, such as ornamental fish, ferocious fish and shrimp, while Artemia has a short s...
