Survey on viability of Streptococcus iniae in frozen rainbow trout (Oncorhynchus mykiss) following experimental infection

Streptococcus iniae is one of the most important agents that causes high mortality and losses in rainbow trout farms in Iran and the world. These bacteria can affects the consumers and people who deal with aquaculture via affected fish. So, viability of this bacterium in frozen fish and fish product can be useful for health care of consumers. A total of 90 rainbow trout, with average weight of ...
