The seasonal variation of Acartia copepods from the waters of Peninsular Malaysia was studied via monthly observations at 2 fixed stations on the west coast (Pulau Pinang and Port Dickson) and 2 fixed stations on the east coast (Kijal and Penyabong)

It is known that zooplankton migrate vertically to avoid UV-radiation (UVR, 280–400 nm), but little is known if such avoidance happens horizontally. Here, we showed that the copepod Acartia pacifica avoided UV irradiated fields horizontally. Exposure

The seasonal occurrence of Acartia pacifica ( Copepoda; Calanoida) and their resting eggs in the sediment of Xiamen Bay were documented between October 2002 and September 2003. The number of viable eggs in the sediment increased from January to May

Many estuarine and coastal planktonic copepods depend on the hatching of benthic resting eggs for recruitment of nauplii to the water column population. The distribution and abundance of viable resting eggs of Acartia pacifica in the Xiamen Bay were
