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, brine shrimp, is a worldwide distribution of small crustaceans. The growth and development of Artemia has metamorphosis, which mainly goes through the stages of egg, nauplii, post-nauplii, 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 marine fish, In the process of shrimp breeding, the importance of Artemia is irreplaceable. The adult Artemia is the final form of Artemia, and the body length is usually 0.7 to 1.5 cm. High-quality Artemia adults are bright red in color, plump in shape, strong in vitality, and have good food attraction, especially in the stage of grouper...

AI Technical Summary

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 gradually increase, eventually leading to the emergence of Artemia populations. more likely to crash

2. Indoor semi-intensive cultivation of Artemia is currently a common way to cultivate Artemia. This cultivation mode is mainly carried out in indoor cement ponds or outdoor cement ponds covered with rainproof sheds, which increases the controllability of the cultivation and stabilizes the output. Sex has increased, and its output is generally 0.5kg / m 3 ~2.0kg / m 3 , but the artemia cultured in semi-intensive culture is dull and blue in color, poor in vitality, poor in food attraction, and low in output and input.
