Large scale introduction and proliferation of brine worms in salt fields: The introduction and proliferation of brine worms refers to the planned inoculation of brine worms from elsewhere into certain water bodies suitable for brine worm growth in areas where there is no natural growth of brine worms, allowing them to grow and reproduce naturally, forming a dominant population of brine worms. Introduction can be divided into permanent introduction and temporary introduction. One introduction can permanently establish a population of brine worms in a certain water area, which is called permanent introduction. Brazil is a typical example of successful introduction of brine worms, and successful trials of temporary introduction have been conducted in countries such as Thailand and the Philippines.

Outdoor large-scale breeding: For large-scale outdoor breeding of brine worms, soil and cement ponds can be used. At present, it is easy to promote in production by appropriately renovating the existing salt ponds in the salt fields. By digging circular ditches, raising embankments, and other measures, the water depth is maintained at 40-50cm. By systematically applying organic or chemical fertilizers, natural bait is propagated in the pool. Soil pond aquaculture is more common in countries such as Thailand and the Philippines, while cement ponds are more commonly used in India.

Indoor high-density intensive care: Various high-density indoor intensive care systems have been designed and tested in economically prosperous and technologically advanced countries such as Belgium, Japan, and the United States, which do not have natural brine insect resources. In general, under intensive care mode, the density of brine worms can reach 10000-20000 individuals/L.

At present, there are mainly two farming methods: a. Batch farming: This method is designed based on the shrimp seedling cultivation method of MOCK et al. Using ventilation to drive water circulation, water is generally not changed during a breeding period. The main bait used is rice bran, with particles smaller than 50 microns. Under the conditions of an inoculation density of 10000 sterile larvae per liter of water and a water temperature of 25-30 degrees Celsius, after 2 weeks of cultivation, the average length of brine worms can reach about 8mm, and each cubic meter of water can produce about 5kg of fresh brine worms, consuming 4kg of rice bran. b. Circulating water flow cultivation: Circulating water flow cultivation is a high-yield technology that eliminates waste such as feces and residual feed of brine worms through continuous renewal of seawater for high-density cultivation. The key to success is the filtering device, which not only removes waste but also does not damage or lose brine worms.
