STUDY ON THE USE OF GREEN BETAL LEAF (Piper betle L) EXTRACT AS ANESTHETIC MATERIAL IN FRESHWATER LOBSTER (Cherax quadricarinatus)

Abstract

ABSTRACT 

This study aimed to determine the best dose of green betel leaf extract to stun freshwater crayfish and the best transport medium. The research method used was an experimental method with green betel leaf extract treatment, namely K₁ (100 mL/4L fresh water); K₂ (200 mL/4L fresh water); K₃ (300 mL/4L fresh water); K₄ (400 mL/4L fresh water). In addition, this study also determined the best transportation media, namely the use of cold sawdust and the use of crushed ice in the first layer with a storage time of 3 hours. The parameters used were the length of time passed out and survival. The results of the study concluded that the best dose to stun the lobsters was the administration of 400 mL/4L fresh water (K₄) with green betel leaf extract and 33 minutes of stunning. While the best transportation media used was the use of cold sawdust with 100% survival rate.
