| Summary: | bstract
Several indigenous swamp fish species have been successfully domesticated and cultivated by fish farmers in
Sumatera, Indonesia. However, the hatching phase in hatcheries commonly encounters fungal infections attributed to Saprolegnia
sp. This study investigates the efficacy of betel leaf extract in protecting the eggs of kissing gourami and climbing perch from
saprolegniasis. Mimicking natural infection conditions, all eggs were exposed to 5 artificially infected eggs per tank. Prior to
infection, the water was treated with betel leaf extract at various concentrations. Results indicate that betel leaf extract
significantly protects the eggs from this fungal infection. For the climbing perch, the optimal dosage was determined to be 300
mg L
-1
, resulting in a hatching rate of 90% and a prevalence rate of 10%. For the kissing gourami, the optimal dosage was found
to be 120 mg L
-1
, resulting in a hatching rate of 86.66% and a prevalence rate of 13.34%. |
