Stripping of lumpfish eggs and milt was compared to dissection of gonads with emphasis on bacterial growth and detection of known pathogens. Disinfection of newly fertilized eggs or eyed eggs was tested using iodine or glutaric aldehyde. Effects of handling on egg development and hatching was investigated in two experiments. No major differences in bacterial counts observed between stripping and dissection of gonads. Disinfection during egg hardening can not to be recommended while disinfection at the eyed egg stage improved hatching. It is not recommended to handle or transport Lumpfish eggs during the first week post fertilization, and not too close to hatching.
