Abstract

The invention relates to an indoor high-density cultivation method of artemia. Filtered seawater is injected into a culture pond to form artificial rich water; in the morning, artemia eggs are treated and then are rapidly placed in the culture pond for hatch, and the illumination intensity is kept at 30-60 mu mol / m<2> / s; artemia artificial food is put in the morning when artemia larvae are hatched; in the culturing process, the dissolved oxygen of a water body is kept at above 0.7mg / L; a biology control method is used for regulating and controlling water quality and adjusting the body color of the artemia; after 10-15 days of cultivation, the artemia is harvested according to the need of market. An indoor cultivation mode is adopted, outdoor severe weather is effectively avoided, better cultivation water environment can be kept, the rapid growth of the artemia is effectively improved by the regulation and control on the water quality and the water color and the preparation and treatment of the artificial food, the quality and output of the artemia are very obviously improved and increased, the food calling property is enhanced, and guarantee is provided for the development of marine aquaculture industry.

Description

technical field

[0001] The invention belongs to the field of aquaculture, and relates to a breeding method for Artemia, in particular to an indoor high-density breeding method for Artemia. Background technique

[0002] Artemia, also known as Artemia and Artemia Shrimp, is a small crustacean distributed worldwide. The growth and development process of Artemia has metamorphosis, mainly through the stages of egg, nauplii, post-nauplius, pseudo-adult stage larvae, and adults.

[0003] Since Seale (1933) & Rollefen (1939) first used newly hatched Artemia nauplii as bait for juvenile fish in the 1930s, Artemia has been widely used in aquaculture, especially in recent years in marine fish, In the process of raising shrimp seedlings, the importance of Artemia is even more irreplaceable. Artemia adults are the final form of Artemia development, and the body length is usually 0.7-1.5cm. High-quality Artemia adults are bright red in body color, plump in shape, strong in vitality, an...

Examples

Embodiment

[0028] Choose 16 breeding ponds, size 3m×2m×1.5m, volume 9m 3 , Seawater treatment adopts sand filter tank filtration system, and air supply adopts conventional support equipment.

[0029] The above-mentioned 16 breeding ponds were divided into four groups, namely Group A, Group B, Group C and Group D, with four ponds in each group. Inject the filtered seawater into the breeding pond, the water depth is 1.2m, and the water body volume is 7.2m 3 .

[0030] Mix the raw Bacillus powder, fish meal, and rice bran with a particle size of 1 to 30 μm in a mass ratio of 1:10:10, then add amino acid fertilizer and water in an amount of 1 mL per gram of fish meal, and then add 1 mL per gram of fish meal Add 10-30mL of seawater, inflate and stir for 3-5 hours to fully mix the ingredients and obtain the fertilizer-water complex.

[0031] Feed a: Mix rice bran, fishmeal, flour, soybeans, and vitamin complexes with a particle size of 1-30 μm in a ratio of 100:20:10:10:1, and then crush th...
