Based in Indonesia, Anwar Hasan, MSc has served as Regional Technical Manager – Aquaculture for Biomin Singapore Pte Ltd in the Asia Pacific region since 2014.
At ILDEX Vietnam, on the afternoon of Friday 25 March he will be speaking at Perendale's very own Aquatic Update conference. His presentation will be titled 'Strategy to control Vibrio levels in shrimp gut to optimise production.'
Here's a brief run-down:
The shrimp industry should be paying more attention to bacterial diseases caused by Vibrio spp. Acute Hepatopancreatic Necrosis Disease (AHPND) has been linked to Vibrio parahaemolyticus, and a new report shows that AHPND toxin genes could also found in V. harveyi. Vibrio also has a role in co-infections with viral pathogens. Thus it is important to control Vibrio levels in the shrimp gut as well as in the pond water. There are several options to control Vibrio in the gut. Organic acids and phytochemicals are potential antibacterials.
In this study, we evaluated the effects of Biomin's antibacterial product Biotronic® Top3 - a mix of organic acids, phytochemicals and a Biomin permeabilising complex - on controlling Vibrio level in the shrimp gut. A field study was conducted at a shrimp farm, with 3 ponds each as control and treatment. The results show that in the treatment ponds Vibrio levels in the shrimps' guts was 104 cfu/ml during observation until DOC 60. This was lower than in the control ponds, which had levels of 105 cfu/ml on DOC 45 and 60. Neither the acids nor the phytochemicals in Biotronic® Top3 had any negative effect on shrimp growth: the ADG was 0.2 g/d. In conclusion, application of Biotronic® Top3 could manage Vibrio levels in the gut without any negative effects on growth.
