ABSTRACT
This research aims to study the ability of Aloe vera (Burm.f.), extract to treat Koi fry [Cyprinus rubrofuscus (Lacépède, 1803)] which is attacked by Aeromonas hydrophila (Chester, 1901). The method used was the experimental method using a completely randomized design with five treatments and three replications was applied. The treatment used was immersion with A. vera extract with a concentration of treatment A
(0 mg kg–1), B (150 mg kg–1), C (300 mg kg–1), D (450 mg kg–1) and E (600 mg kg–1). The variables observed were in vitro test, LC50-24-h test, clinical symptoms which included damage to fish body, fish feeding response and fish response to shock which were analyzed descriptively comparatively. The results showed A. vera extract has the ability as an antibacterial with inhibition zone diameter reaching 20.49 mm at a concentration of 5 000 mg kg–1 and LC50 test 48 h (in vivo test) of 1 157.16 mg kg–1, so for the treatment of fish use concentrations below that concentration. The use of aloe vera extract with a concentration of 300 mg kg–1 for 48 h was effective to treat koi fry infected with A. hydrophila by healing relatively fast body damage, response to feed and shock is normal and fast.
