Investigation of potential aquatic plants as herbal biomedicine to treat fish diseases

Abstract

Fish disease caused by bacteria is a big problem in the aquaculture industry. Solutions for handling this disease have been done a lot, one of which is the use of plants as herbal biomedicine. The purpose of this study was to find potential aquatic plants in the prevention of bacterial fish diseases. Aquatic plants have more advantages including being able to absorb contaminants in the waters and provide additional oxygen to the waters. The research was carried out in-vitro tested on 22 species of aquatic plants from South Sulawesi Indonesia with concentrations of 0.1 gr and 0.2 gr of ethanol extract. The fish disease bacteria tested ie: Aeromonas hydrophila, Flexibacter columnaris, Streptococcus agalactiae, Edwardsiella ictaluri. The results showed: 22 aquatic plant species tested, 8 of them have the potential to control fish diseases, they are Pleocnemia sp, Phymatosorus scolopendria (Burm.f.) Pic.Serm, Selaginella plana (Desv. Ex Poir) Hieron, Humata repens (L.f.) J. Small ex Diels Syn, Donax canniformis (G. Forst.) K. Schum, Hymenachne amplexicaulis (Rudge) News, Ludwigia adscendens (L.) H. Hara, Eclipta prostrata (L.) L. Two species i.e Selaginella plana (Desv. Ex Poir) Hieron and Eclipta prostrata (L.) L., are capable of inhibited the growth 3 type of bacterial fish disease tested.
