UNAIR NEWS – Cultivation of catfish is easy and the fish is popular among the communities, noth for the fish farmers who are just doing it as hobby and commercial entrepreneurs handle the commodity merchandise on a large scale.

But be aware, the diseases of catfish like ulcer disease or known as motile aeromonas septicemia(MAS) can disrupt the growth of fish. Catfish will be bloated, float and die. So the use of natural ingredients is used, in this case Bougenville flowers .

It attracted the attention of three students from Aquaculture PSDKU Universitas Airlangga in Banyuwangi, Rina Suliestyana, Diyas Kamila Alif, and Ayu Nur Imaniy. They tried to find an alternative solution to the problem by submitting the proposal PKM Exacta Research (PKM-PE).

Under the guidance of Mohammad Faizal Ulkhaq, S.Pi., M.Si., UNAIR lecturer in Banyuwangi, their study entitled “In Vivo Study of Bougenville Extract ( Bougainvillea Glabra ) As Anti Aeromonas Hydrophila for Catfish ( Clarias Gariepinus )” passed the funding from Dikti in PKM 2018.

“MAS disease can infect catfish and also attack all types of freshwater fish. MAS disease is mainly caused by Aeromonas hydrophila. Death from A. hydrophila infection can reach 100%. Common treatment used is antibiotics, “said Rina Suliestyana, the leader of PKM-PE team.

One of the efforts in order to overcome MAS incident is by utilization of natural ingredients that have certain properties as a traditional medicine.

Rina Suliestyana also said that the purpose of this study to analyze the content of antibacterial compounds in the Bougenville extract  and to determine its effect to the survival rate of catfish infected by Aeromonas hydrophila .

This study was conducted for five months, starting from March to July 2018, located in the laboratory of Universitas Airlangga PSDKU in Banyuwangi. The study used Completely Randomized Design (RAL) with four treatments and five replications. Parameters observed were gained weight, growth rate, feed conversion, and survival rate.

“The results showed that the test of Bougenville extract as Aeromonas hydrophila anti bacterial  can inhibit the growth of bacteria in catfish that has been given bacteria Aeromonas hydrophila. Bougenville extract with 100% concentration is considered more effective to inhibit bacterial growth, ” said Rina.

With the study of antibacterials derived from this Bougenville plant, it is expected to be useful as an alternative antibacterial which is easy to use.

In the future, Bougenville extract antibacterials that have been used for this cultivation activity will be registered to obtain patents, so that can be circulated to the community as affordable anti-bacterial. (*)
