The Efficacy Of Herbal Plants Extract Against Infection Of Aeromonas Hydrophila, Staphylococcus Xylosus And Streptococcus Agalactiae In Snakehead (Channa Striata) Fish
Preliminary screening was done for 13 plants species belonging to member of nine families such as Senna spectabilis, Jacaranda filicifolia, Samanae saman, Tamarindus indica, Carica papaya, Andira inermis, Morinda elliptica, Coleus aromaticus benth, Citrus hystrix, Milletia pinnata, Cymbopogon nardus...
