THE EFFECT OF MARINE SPONGE Aaptos aaptos EXTRACT IN VIBRIOSIS TREATMENT OF BLACK TIGER SHRIMP Penaeus monodon LARVAE
Abstract: Black tiger shrimp
Penaeus monodon post larvae were challenged with Vibrio harveyi and butanol
extract of selected marine sponge Aaptos aaptos to determine its antibacterial
bioactive potential in vibriosis treatment. Based on the preliminary toxicity
study, the A. aaptos butanol extract with concentrations of 31.25, 62.5, and
125 mg/L were selected in the study. Black tiger shrimp post larvae were
challenged with V. harveyi at 107 cfu/mL and immersed A. aaptos butanol extract
with the concentration of 125 mg/L showed significantly in (P<0.05) decrease
mortality of the post larvae treated. Besides at this concentration, V. harveyi
population in the rearing water and the post larvae treated decreased compared
to control (untreated post larvae). Histological observation indicated that
there was no changing on hepatopancreas of the black tiger shrimp post larvae.
Based on this result, it is suggested that the butanol extract of A. aaptos is
a potential bioactive compounds source in the treatment of vibriosis which may
replaced the current antibiotics application.
