How to prevent and treat saprolegniasis in pufferfish? A detailed explanation of prevention and treatment techniques for common diseases in aquaculture
1. Causes Saprolegniasis, also known as water mold disease or white hair disease, is mainly caused by fungi such as Saprolegnia or Achlya invading through wounds on the fish body surface resulting from careless operations such as netting, transport, pond transfer and artificial breeding of broodstock with induced maturation and spawning, or from net-cage fish farming causing abrasions on the fish body surface, or from parasites damaging the fish body surface.

What to do about coughing and wheezing in weaned piglets? Experience sharing on traditional Chinese medicine prevention and treatment in pig farming
Coughing and wheezing in piglets from 10 days after weaning to 30 kg body weight is usually associated in Western veterinary medicine with porcine postweaning multisystemic wasting syndrome (i.e. circovirus) infection, with an incidence rate ranging from 20 percent to 45 percent; the mortality rate of affected piglets is generally 30 percent, and can reach as high as 80 percent, with body temperature of 40.5°C to 41.5°C. Piglets show rough and disheveled coat, affected pigs have diarrhea combined with respiratory symptoms and neurological symptoms, severe emaciation, and death from exhaustion. This disease poses a very great threat to the pig farming industry. It is most severe in the three seasons of spring, autumn and winter. In traditional Chinese veterinary medicine theory, this disease belongs to warm disease symptoms; the cause is external contraction of wind pathogen invading the lung, and cold, summerheat, dryness, warmth and the like can all combine with it. The main site of the lesions is in the lung. In traditional Chinese veterinary medicine theory, lung qi governs respiration and opens into the nose, externally corresponding to the skin and hair, and governs the opening and closing of the interstices. When lung qi is sufficient, the opening and closing of the skin and interstices is normal, and external pathogens are not easily able to invade; otherwise the pig body is plagued by disease. Using Qingfei Zhike San combined with Maxing Shigan San with modifications, this formula can pungent-cool diffuse and vent, clear the lung and calm wheezing, clear and purge lung heat, and resolve phlegm and stop coughing. Add it to piglet feed as a powder at 0.6 percent, continuously for 2 to 3 weeks. In Western veterinary medicine theory, this formula is believed to have fairly strong antibacterial and inhibitory effects on Actinomyces pleuris, Staphylococcus aureus and Pneumococcus; this formula also has effects such as anti-influenza virus action, and also has obvious antipyretic and anti-inflammatory effects, and can improve the immune function within the animal body.
