IPB University Lecturer Explains the Advantages of Probiotic Applications in Shrimp Cultivation


The Aquaculture Student Association (Himakua) IPB University again held the Aquafest 2022 offline at the Andi Hakim Nasution Auditorium, 18/9. The theme is The Shining World of Aquaculture. Aquafest was attended by the Director General (Dirjen) of Aquaculture Ministry of Maritime Affairs and Fisheries (KKP) RI and Prof. Widanarni (IPB University Lecturer from the Faculty of Fisheries and Marine Sciences/FPIK) who explained the application of probiotics for disease prevention in shrimp farming.

According to Prof. Widanarni, vaname shrimp is one of the leading commodities in Indonesia, even in the world. When viewed from the production value, compared to other shrimp species, vaname shrimp is much higher. To achieve this high production, intensification is carried out. Shrimp are reared in high density, given artificial feed, and applied with disinfectant to eradicate microbes.

“With intensification, production is indeed much higher. However, there are problems in this intensive system, namely a decrease in the quality of the cultivation environment and an increase in disease attacks," he explained.

According to the survey results of The Global Aquaculture Alliance's GOAL (Global Outlook for Aquaculture Leadership) in 2019, the biggest challenge in shrimp farming is disease. Until now, shrimp disease caused by a virus is still growing.
He explained that there are important ecological systems in natural ecosystems and aquaculture, namely production, consumption and decomposition. In low density aquaculture systems, the system is balanced, so in extensive systems, the problem is less of a problem. With intensification and increasing stocking density, the implication is increasing the need for external feed and the need for disinfectants. As a result, there is a system imbalance that can threaten the sustainability of cultivation.

"What is expected in aquaculture in the future, of course we are still required to have high productivity, remain efficient in using resources, but must have minimal environmental impact," he added.

He added that environmentally friendly technologies include Biofloc, integrated multi trophic aquaculture (IMTA), and recirculation with biofilters and aquaponics. According to him, the use of this technology requires strong regulation from the government.
“Microbes themselves can be used as probiotics to prevent shrimp disease by increasing immunity. These microbes were isolated and selected from shrimp and the environment. This selection is adjusted to the needs of the host, then it can be mass produced and the application is easy,” he added.

According to him, this probiotic has several mandatory and recommended criteria. For example, non-pathogenic and capable of being antagonistic to several pathogenic bacteria. The application can be mixed in artificial feed or directly into culture media. Its supply must of course meet the requirements in rule 1/Permen-KP/2019 regarding the requirements for the provision of probiotics.

Meanwhile, he continued, prebiotics can increase the role of probiotics that can only be grown in small amounts on media. Prebiotics cannot be digested by the host but provide beneficial effects for the host and provide health effects. When probiotics and prebiotics are combined, they become synbiotics that have a better effect on the overall health of shrimp.

“Various studies have been carried out for the application of synbiotics in shrimp and have shown positive results. The result is able to improve growth performance, immune response, and resistance. In addition, research on probiotics in humans is actually already advanced so that it can become a role model for the development of probiotics in aquaculture," he concluded. (MW/Zul) IAAS/ELS
