Use of homeo drug for curing ulcerative syndrome in fishes

Fungal infection was observed in Catla catla and Labeo rohita cultured in two private fish farms. The later stage of the infection resulted in ulcerations followed by haemorrhage on the dorsal surface of the body. Initially, usual treatments of copper sulphate, potassium permanganate and common salt solution were tried, but no improvement was observed. Then repeated intramuscular injections of homeopathic drug Heaper Sulpher and Arnica spray were given with encouraging results. Infection reported in another farm was also successfully controlled using a similar treatment.

Some aspects of curing of sharks and rays

A simple method for eliminating urea almost completely from elasmobranch muscle consists in desalting the initially salted muscle in 5% brine. The initial salting removes about 58% of the urea, which occurs to the extent of 5.8 to 7.5% D.W.B. in the fresh muscle, and the desalting further reduces the urea content to negligible quantities (0.2%).
