Method for indoor low-cost high-density sustainable cultivation of artemia

Abstract

The invention relates to a method for indoor low-cost high-density sustainable cultivation of artemia. Filtered seawater at a suitable temperature is injected into a culture pond and then artificial water full of fertilizer is formed; artemia eggs are hatched in a container with the conical bottom, fairy shrimp larvae collected after the hatching for 12-16 h are placed in the culture pond to be cultured; artemia artificial composite feed are fed on the next day of inoculation to guarantee balanced nutrition of artemia in the growth and reproduction process; continuous aeration is performed in the culture process, and dissolved oxygen is maintained at 5 mg / L or above; after being cultivated for 9-15days, the artemia is collected as required; the self-reproduction and sustainable cultivation of the artemia can be performed in a timely pond division mode on the premise of not supplementing newly hatched artemia, and the cultivation scale is expanded continuously. The indoor low-cost high-density sustainable cultivation of the artemia is performed through optimization of artificial feed and timely pond division. Weather factor interference is effectively avoided, a good cultivation water environment is maintained, and the cultivation cost is reduced. Through water quality regulation and preparation and treatment of the artificial feed, the growth speed and yield of the artemia are effectively improved, the artemia quality is stabilized, and the industrial development of China's aquaculture is guaranteed.

Description

Technical field: [0001] The invention relates to a method for cultivating Artemia, in particular to a low-cost, high-density and sustainable cultivating method for large indoor pools of Artemia, belonging to the field of aquaculture. Background technique: [0002] Artemia, commonly known as brine shrimp, brine shrimp, or brine shrimp, is a small lower crustacean and is widely regarded as an important biological bait. The body color of Artemia is off-white, and the individuals living in high-salinity brine are red. Artemia adults are slender and segmented, and can be divided into three parts: head, thorax and abdomen, without carapace. [0003] The artemia breeding industry is an industry that has developed worldwide in recent decades. Artemia breeding has been carried out in our country since the mid-1980s and has made great progress. At present, the development and utilization of Artemia have achieved good social and economic benefits. Especially in recent years, with th...

Problems solved by technology

[0004] In recent years, with the promotion of factory farming of grouper, seahorse and other rare fish species, the demand for live biological bait is increasing. At present, there is no other artificial bait that can effectively replace live biological bait

Due to the lack of strict control of the cultivation conditions in outdoor extensive cultivation, there are problems such as unstable output, short continuous supply time, and susceptibility to virus and bacterial contamination, which cannot guarantee the stability of the quality of Artemia and the timely supply of sufficient quantities; in addition, as With the increase in the demand for eggs, the price is only high but not low. The purchase of eggs has become one of the main costs of raising fish and crustaceans. For example, in the breeding of prawns, the cost of buying Artemia eggs accounts for 30~30% of the cost of raising seedlings. 50%, so the exploration of indoor breeding technology for Artemia has always been a hot topic

The existing indoor culture of Artemia still has problems such as high feeding frequency, cumbersome operation, low breeding density, and lack of sustainable cultivation.
