Problems solved by technology

[0003] At present, people have different opinions on the salinity, pH, light intensity, and incubation time required for Artemia hatching. Therefore, most of the research on Artemia hatching focuses on the above aspects. No one has proposed the impact of different energy lights on Artemia hatching. For example, the influence of yellow light on hatching diapause Artemia eggs, and how to hatch diapause Artemia eggs in a yellow light environment, and these problems will affect people's correct understanding of Artemia hatching, which is not conducive to further improving the hatching rate of Artemia, As well as realize the hatching of diapause Artemia eggs under the yellow light environment, while ensuring the stability of the hatching rate

Embodiment 1

[0020] Use a transparent incubator and a 250ml incubation tube for incubation, and 200ml of incubation solution in the incubation tube for incubation. The hatching solution is prepared by mixing artificial sea crystals with tap water, and its salinity is 18g dissolved salt / liter; pH value is 8.1; the concentration of dissolved oxygen is >6mg / L; the water temperature is 28°C;

[0021] Yellow light is irradiated on the liquid surface of the hatching solution, and the light intensity of the yellow light is 2200 lux.

[0022] The density of the diapause Artemia eggs in the hatching solution is 2 mg / L; and the Artemia eggs of Kazakhstan are used.

[0023] After 24 hours of incubation, the hatching rate of Artemia eggs reached 82%.

Abstract

The invention provides a method for hatching diapause brine shrimp eggs in yellow light. According to the method, the diapause brine shrimp eggs are hatched in hatching solution under the density of 1.5-2.5mg / L, the hatching solution is 17-19g of dissolved slat per L in salinity and 8-9 in pH, concentration of dissolved oxygen is greater than 6mg / L, water temperature of 27.5-28.5 DEG C, and the yellow light is 2000-2500Lux in luminous intensity. Hatching the diapause brine shrimp eggs in the yellow light is achieved; by controlling the factors such as luminous intensity, temperature, pH and dissolved oxygen, the rate of hatching the diapause brine shrimp eggs in the yellow light can be effectively increased, and 24h hatching rate reaches greater than 82%.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for hatching diapause Artemia eggs under yellow light. Background technique [0002] Artemia (Brine shrimp, Artemia), commonly known as Artemia, is a class of small crustaceans that live in high-salinity waters. The nauplii of Artemia that hatch for 1-2 days have a large amount of yolk, rich in protein, Fat is a good opening bait for larvae such as fish, shrimp and crab, which can greatly improve the survival rate of artificial breeding of fish and shrimp without polluting water quality. [0003] At present, people have different opinions on the salinity, pH, light intensity, and incubation time required for Artemia hatching. Therefore, most of the research on Artemia hatching focuses on the above aspects. No one has proposed the impact of different energy lights on Artemia hatching. For example, the influence of yellow light on hatching diapause Artemia eggs, and how to hatc...
