Natural remedies against vibriosis in shrimp culture - Liptosa
Published:July 14, 2017
Summary
A phytobiotic was able to reduce Vibrio counts in intestine and hepatopancreas leading to an increase in survival and better health. Shrimp farming is growing very fast in recent years, due to the high profit margins which present a good opportunity for those with interest in this sector. In Asia the production of Pacific white shrimp (Litopenaeus vannamei) was more than 3 million t...

It is very good information for my work.
I would like to translate this article into Vietnamese and dissemination for the shrimp in Vietnam?
Hoping to get the consent of the author
Best regard.
Hello Cristina,
I am working at Research Institute for Aquaculture number II (RIAII) in Viet Nam, I will translate it to Vietnamese and upload on organization's website.
Thanks for your consent.

Good laboratory scale trial. It would be very interesting to know the cost benefit analysis when applying this product in commercial scale. Also, any idea of MIC break points of this product against the pathogenic Vibrio parahaemolyticus strain that causes AHPND/EMS and pathogenic Vibrio species that cause WFS. This information could give some idea whether lessor doses (less than 5kg/ton) can be applied.
LIptosa is a Spanish manufacturer of additives phytobiotics and Liptoaqua is the aqua department. Our additives are natural growth promotors and immunostimulants working on gut health through prebiotics. We manufacture tailor made additives for each species and pathology. We have phytobiotics for fish and shrimp regarding the different pathologies: bacteria (gram + and -), intracellular parasites (gregarines) and ectoparasites( gill and skin such as monogenea, gyrodactilus, trichodinas...), etc.
Please, once you have the translation done and uploaded I would appreciate you send me the link to cristina.garcia@liptosa.com
Dear Subashni Bhoopathy, I Think Dr. Niti used fish oil to bind the feed with our phytobiotic. About the FCR, these prebiotics are immunostimulants helping the animal grow better and more efficiently, the better health has the shrimp the better will eat, therefore nutrient absorption is more effective and so the animal grows faster, improving zootechnical parameters as FCR, ABW, SV. Regards,
Dera Dr. Christopher Hettiarachchi. Thanks for your comments. Regarding your questions Liptofry has a strong bacteriostatic power so is useful to reduce v. Parahemliticus concentration during clinical episodes. Doses must be applied according to rate feeding. Recommended doses 3-5 Kg/Mt feed .; other positives effects of Liptofry such as better growth appears in this range of use. Regards.
Dear Cristina Garcia Diez, How did you come up 3-5 kg/tonne value? Why should one not use less than 3 kg/ tonne? And since there is a decrease in the survival rate of shrimps on using 8 kg/tonne, can this phytobiotic be toxic? Did you analyse the toxicity of your compound?
The MIC done at Kasetsart University showed a concentration of 10mg/ml at 10*6 CFU for V.parahaemolyticus white feces and EMS strains. Feed intake % was the same for the 3 batches. With phytobiotics not always the best dose is the higher. Plants can have a strong flavour and sometimes animals just reduce the intake because of that, that is why lower doses sometimes shows better results.
Despite we have not done toxicity analyses to this specific phytobiotic, from our experience we know we are far from the maximum level of toxicity. Of course, you can use doses below 3kg, as said, that depends on % feed intake, as well as on results you want to achieve, maybe you just want to use it as a growth promoter or as bactericidal or intermittently, etc. But our recommendation is 3-5kg/Mt at first instance.
