A new technical article has been published and is available at Engormix.com, entitled The Safety and Efficacy of a Streptococcus iniae Vaccine in Asian Sea Bass by Nantarika Chansue, Jirasak Tangtongpiros and John S. Clark
A European system of immersion followed by injection vaccination is indicated as the strategy of choice in the control of this pathogen. Asian sea bass (Lates calcarifer), also known as barramundi, is becoming increasingly popular as a food fish in export markets such as the US and EU. As demand increases, more and more farms are appearing in the South East Asian region to supply these growing markets.
Concomitantly with the rise in production is increased disease risk. In hatcheries, sea bass larvae are prone to Vibrio infections and to Viral Nervous Necrosis (VNN); in the nursery culture phase, Vibrio, S. iniae and Iridovirus are problematic. In both these phases of culture, protozoan ecto-parasites such as scuticociliates are prevalent. Risk is greatest, however, during the grow-out phase of culture.
Ecto-parasites such as capsalid flukes and sea lice are prevalent and conventional bathing treatments are ineffectual. There is a need, currently being addressed, for in-feed treatments to control and eradicate these parasites. Read more...
