Abstract

Successful molts and morphological defects in P. monodon zoeae (Z₁, Z₂, Z₃) resulting from a 24-h exposure to 1.0 and 2.0 mg/L furanace in baths of 1.0 and 2.0 mg/L were quantified. Molting was delayed in Z₁, but not in Z₂ and Z₃ at 1.0 mg/L; considerably delayed in all sub-stages at 2.0 mg/L. Morphological defects in the telson, carapace, uropods and pereiopods were observed in high frequency in Z₃ after the exposure. These abnormalities did not result in 1.0 mg/L. In Z₂, a 6-h exposure is deemed optimum for bath in 1.0 mg/L as gauged from higher survival of larvae after 96 h.
