<i>Streptococcus iniae</i> Infection of Tilapia <i>Oreochromis niloticus</i> in a Recirculation Production Facility

Abstract

Abstract— Streptococcus iniae was isolated from moribund pure strain Nile tilapia Oreochromis niloticus in a water recirculation aquaculture facility. The extent of the infection was determined in a number of separate culture systems at the facility. A pilot study was also conducted to gain information on potential stressors that may play a role in spread of the infection within such a water reuse facility. The conditions employed in the pilot stress test did not have any apparent impact on spread of S. iniae infection to fish in additional tanks within the facility.
