Abstract: Abstract: A total of 178 copepod species were identified in an upwelling area of the Mienhua Canyon off northern Taiwan, western North Pacific during a spring cruise in 1995. Paracalanus aculeatus, Oncaea venusta and Clausocalanus furcatus were the three dominant species, comprising 43% of the total copepod numbers. Most copepod species performed normal diel vertical migration, descending during daytime and ascending at night to different depth zones and with different rates. Some dominant copepod species, such as P. aculeatus, C. furcatus, Temora discaudata and Canthocalanus pauper, apparently congregated in the surface water (between 0 and ∼1 m) at night but became sparse in the upper 250 m of the water column during the day. Some copepods stayed in deeper water and occasionally ascended to the subsurface layer at night or twilight (i.e. Subeucalanus mucronatus), while others exhibited no apparent diel vertical migration or reverse diel vertical migration in the depth below the subsurface layer.
