How to use high-polymer iodine when disinfecting fish fry

Winter is the peak season for fish saprolegniasis, so disinfection of fish fry must focus on preventing and treating saprolegniasis. After the specific drug malachite green was banned, high-polymer iodine is a relatively ideal drug for preventing and treating saprolegniasis. The full name of high-polymer iodine is compound S high-polymer iodine. It has an extremely strong killing effect on bacteria, viruses, and fungi, and its bactericidal capacity is more than 10 times higher than that of povidone iodine. In addition, high-polymer iodine contains a relatively high proportion of traditional Chinese medicine ingredients, and for fish fry injured by net-pulling operations and long-distance transport, it has the function of healing wounds extremely quickly.

How to use high-polymer iodine: for soaking and disinfecting fish fry, use 10 grams of the drug per cubic meter of water, and soak for 10-15 minutes; for whole-pond splashing, the concentration is 100 to 150 milliliters per mu for a pond 1 meter deep. Fish fry should be disinfected promptly, and as far as possible, disinfect the fish fry on the same day they are stocked. In winter and spring, do not use table salt to disinfect fish fry, so as to avoid damaging the mucus on the fish body surface and causing fish fry death.
