Abstract
The streptococcosis produced by Lactococcus garvieae is a major world wide disease present in Spain. In this study are described the different courses of disease, depending on age of diseased fish. While 50g fish have more se nsitivity, and suffer longer acute period of disease, 100g fish are able to eliminate bacterial agent from internal organs. However, bacteria is maint ained in organs related to bacterial elimination, such gills and intestine. Bacteria could also be isolated from fish aquarium water.
