Indoor high-density cultivation method of artemia

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...

Problems solved by technology

Outdoor pond culture is affected by the weather and the abundance of bait in the water body, and the output is very unstable. In bad weather, all populations may die in a short time, and the continuity of culture cannot be guaranteed. Moreover, outdoor pond culture is affected by the hydration factor of the culture water. Limits (such as dissolved oxygen, pH, ammonia nitrogen, etc.) are relatively large. During the cultivation process in large ponds, the concentration of dissolved oxygen in the water body will drop rapidly as the cultivation progresses, and harmful chemicals such as ammonia nitrogen will grad
