Effectiveness of 2-Phenoxyethanol for Anesthetizing Striped Mullet (Mugil cephalus) (Linnaeus, 1758) for Transportation

Abstract

Anesthetized fish transport is creating new opportunities
for aquaculture, as it offers ease of handling
and reduction of stress and helps to reduce
mortality rates. In this study, 2-phenoxyethanol was
administered to Striped Mullet (Mugil cephalus)
(Linnaeus, 1758) to determine its effects on the ease
of handling and transportation. Four dosage levels
were tested—100, 200, 300 and 400 mg l-1. Three
levels of induction and three of recovery were
recorded. The lowest effective concentration was 300
mg l-1. At this dosage, the time required to achieve
the final stage of induction was 159±13 s (mean ±
SD) and that to achieve the final stage of recovery
was 193±16s. These times are significantly different
from those for the other dosages.
