Iodine Disinfection of Sea Trout, Salmo Trutta (L.), Eggs and the Affect on Egg Surfaces
The aim of the research was to investigate the impact iodine solution disinfection had on Salmo trutta (L.) egg survival rates during incubation, and to determine the effect of the disinfection procedure on egg shells using scanning microscopy. The study groups were bathed in a Desamar K30 solution...
