Effects of furanace on the development of larval stages of Penaeus monodon Fabricius
Share
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.
