[0020] Example 1:
[0021] The cultivation method of the indoor factory-based eco-type specific pathogen-free seed of Litopenaeus vannamei includes the following steps:
[0022] (1) Seedling seawater treatment: first use seawater with a concentration of 0.5g / m 3 Potassium permanganate treatment, flocculation sedimentation time 24h, the effective chlorine concentration of primary chlorine disinfection and secondary chlorine disinfection are 20g / m respectively 3 And 10g / m 3 , Water quality adjustment adding baking soda (NaHCO 3 )40g / m 3 , Disodium ethylenediaminetetraacetic acid (EDTA-2Na) 5g / m 3 , Aerate and mix uniformly, stop the gas to settle for 12h;
[0023] (2) Cleaning and disinfection of indoor nursery ponds: Use a mixed solution of 10L fresh water + 10% effective concentration of iodine solution 50ml + detergent 2~5ml to thoroughly scrub the inner and outer walls of the nursery pond twice, rinse with fresh water and ventilate for 3 days ;
