Postgraduate Student of IPB Created the Artemia Feed with Probiotics for Vaname Shrimp Larvae
Disease attack was still one of the main obstacles in the vaname shrimp hatchery. One of them was the vibriosis disease caused by the bacteria of Vibrio harveyi, which could cause death in all shrimp stadia. The applications of probiotic, prebiotic, and sinbiotic (the combination of probiotic and prebiotic) were one of the alternative disease controls that were environmentally friendly, because it could increase the growth, the immune response, and the shrimp resistance to the disease attack.
Therefore, Hamsah, the S3 student of the Study Program of Aquaculture Science, Postgraduate School, Bogor Agricultural University (IPB), conducted the research to see the growth performance, the immune response, and the resistance of the vaname shrimp larvae given the probiotic of Pseudoalteromonas piscicida, the prebiotic of mannanoligosaccharide (MOS), and the combination of both (sinbiotics) through the bioencapsulated (Biomaterial process as the encapsulation) Artemia. This research was under the guidance of the supervisors of Prof. Widanarni, Dr. Alimuddin, Dr. Munti Yuhana, and Prof. Muhammad Zairin Junior.
In his experiment, Hamsah used the vaname shrimp larvae kept in an aquarium of seawater. The result of the research showed that the total value of hemosit count (THC) and the activity of phenoloxidase (PO) of the vaname shrimp larvae that was given sinbiotic were higher than other treatments. Increased the immunity of the vaname shrimp larvae which was given the probiotic, the prebiotic, and the sinbiotic was also seen from the measurements of the gen immune expression of the shrimp larvae.
“Based on the results of all research phases, it can be concluded that the probiotic of P. piscicida 1Ub, the prebiotic of MOS, and the combination of both (sinbiotics) are capable of improving the growth performance, the immune response, and the resistance of the vaname shrimp larvae to the infection of the pathogenic bacteria of V. harveyi with the best result obtained on the giving sinbiotic,” said Hamsah.(IR/NM)
