Embodiment

[0017] Example: Reference figure 1 , The method of sterilizing squid larvae, the implementation process is as follows:

[0018] During the operation, the squid larvae were continuously inflated with an air pump, and the nutrient-fortified Artemia nauplius was fed twice a day. The temperature of the water in the breeding pond was 19℃ and the salinity was 17‰. The breeding area was set at the mouth of the Yangtze River. Man's needle-free squid breeding ground.

[0019] (1) Temperature and salt adaptation: Move the cuttlefish larvae to be disinfected into a disinfection container with a volume of 10L, and then gradually increase the water temperature and salinity in the disinfection container from the water temperature and salinity of the breeding pond to 30°C. A hot rod heating method is used to increase the temperature, and the water temperature is controlled to not exceed 1 ℃ per hour to avoid a large number of deaths of squid larvae due to a rapid increase in water temperature. ...

Abstract

The invention discloses a sterilization method for a squid larva, which comprises the steps of (1) temperature and salinity adaptation, namely, putting the squid larva to be sterilized in a sterilization container, and then heating water in the sterilization container from the temperature of water in a culture pond to 26.5 to 30 DEG C, and adjusting the salinity from 32 to 36 thousandths; (2) violent change by fresh water, namely, adding fresh water in water in the sterilization container to lead the salinity of water around the squid larva to be reduced from the salinity in the step of temperature and salinity adaptation to below 10 thousandths in one minute, and damaging the surface structure of germ due to inadaptation to low-salinity water when the gem absorbs water; and (3) temperature and salinity recovery, namely, immediately transferring the squid larva after violent fresh-water change to an environment with temperature of 26.5 to 30 DEG C and salinity of 32 to 36 thousandths for temporary culture, and then recovering the temperature and salinity of water to the standard of water in the culture pond. The sterilization method for the squid larva is simple and easy, causes little damage to the squid larva, has low mortality rate, and is environment-friendly and safe.

Description

Technical field [0001] The invention relates to a method for sterilizing aquaculture animals, in particular to a method for sterilizing squid larvae. Background technique [0002] There are various methods of disinfection known in the art. Examples of these embodiments are based on chemical disinfection, radiation disinfection, and other methods. However, these methods have several disadvantages. Chemical disinfection or sterilization is a method that quickly reaches its limit, which will bring about the problem of drug residues. Another example is the use of antibiotics in chemical disinfection. The bacteria become more and more resistant and resistant, and they often Incidentally, it has a certain toxic effect on cultured organisms. However, there are also a small amount of drug-free sterilization methods, such as the Chinese invention patent "Activated water sterilization method and its production device", patent number ZL02108447.5, which discloses an activated water steri...
