What medication should be used to disinfect fish fingerlings? Polymeric iodine works well

Winter and spring are the seasons with a high incidence of fish saprolegniasis, so disinfection of fish fingerlings must focus on preventing and treating saprolegniasis. After the specific remedy malachite green was banned, polymeric iodine is a relatively ideal medication for preventing and treating saprolegniasis.

The full name of polymeric iodine is compound S polymeric 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, polymeric iodine contains a relatively high amount of traditional Chinese medicine ingredients, and for fish fingerlings injured by net-pulling operations and long-distance transport, it has the function of healing wounds extremely quickly.

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