Problems solved by technology

[0005] However, the current application technology of bioflocs is basically limited to fresh water, brackish water and ordinary seawater systems. In terms of Artemia culture technology, there is no establishment of high-density culture of Artemia using bioflocs in high-salt environments. mature technology

Embodiment Construction

[0017] The technical solutions and effects of the present invention will be further described below through specific examples. The breeding site is located in Chengkou Salt Farm, Shandong Province. The area of ​​the breeding pond is 1 hectare, and the breeding time is from July to August. The specific breeding steps are as follows:

[0018] 1) Cleaning of the breeding pond: Drain the original pond water and dry and expose to the sun for a week. To kill fish, fish eggs and other organisms, to provide a better growth environment for Artemia.

[0019] 2) Inject brine with a salinity of 100g / L, a pH of 8.0, and a depth of 50cm into the culture pond; the injected brine is filtered through 1mm and 200μm sieves in advance. Among them, the 1mm screen effectively filters out fish, shrimp and large zooplankton; the 200μm screen filters out Artemia larvae and small zooplankton.

[0020] 3) Put chicken manure, urea and diammonium hydrogen phosphate into the breeding pond regularly, that...

Abstract

The invention discloses a method for artemia culture in a high salinity environment. The method comprises the following steps: (1) injecting brine having the salinity of 80-100g / L to a culture pond, wherein pH of the brine is 7.8 to 8.2, and the depth of a water body is 50 to 100 cm; (2) putting organic manure, urea and diammonium hydrogen phosphate to the culture pond periodically, and inoculating artemia nauplii to the pond with an inoculating density of 100 to 120 in each liter of water body when the density of unicellular algae in the water of the pond reaches 500,000 to 1,000,000 per milliliter; (3) after artemia inoculation, detecting the total nitrogen level in the water body weekly, and adding a carbon source according to a proportion of (C / N) being 10: 1; continuously collecting artemia cysts appearing in the water body in a culture process. Due to the adoption of the technical solution, the wet weight in the yield of artemia cysts in per hectare of culture area after the artemia is inoculated for 6 weeks is over 10kg, and no culture water needs to be changed in the entire culture process, therefore water sources are saved, the energy consumption is decreased and the environment pollution is reduced.

Description

technical field [0001] The invention relates to the field of Artemia cultivation, in particular to a method for cultivating Artemia in a high-salt environment. Background technique [0002] Artemia belongs to Phylum Arthropoda, Class Crustacea, Subclass Branchiopoda, Order Anostraca, Family Artemidae, and is widely distributed in inland salt lakes and insolation In the evaporation pool of the salt field, it is the main biological population in the high-salt waters, and it has two ways of producing offspring: oviparous and oviparous. Artemia is not only the main consumer and ecological regulator in the medium and high salinity salt pan ecosystem, but also an excellent fresh bait for aquatic seedlings. With the rapid development of the aquatic nursery industry, the demand for Artemia eggs is increasing year by year. According to preliminary estimates, the global demand for finished Artemia eggs has reached 3,000 tons in 2010. [0003] Biofloc is composed of bacterial micelle...
