Accumulation and Elimination of Malachite Green in Penaeus vannamei Boone Fingerlings

doi:10.7506/spkx1002-6630-201313015

Abstract

Abstract:

The accumulation and elimination of malachite green (MG ) was studied in Penaeus vannamei boone fingerlings
with the purpose to monitor its use in aquaculture. Penaeus vannamei boone fingerlings 0.9 cm long were exposed to MG
at a concentration of 0.15 μg/mL for 2 h under natural environment. Dynamic changes of MG in Penaeus vannamei boone
fingerlings were monitored by HPLC-MS. The result showed that MG was eliminated rapidly in body and reached below
LOD after 3 d, but leucomalachite green (LMG) was eliminated very slowly and reached below LOD after 9 d. So it can be
used as a target analyte in residue-monitoring programs.

Key words: malachitegreen, leucomalachite green, Penaeus vannamei boone fingerlings, elimination
