ABSTRACT: Between September 2009 and
April 2010, superficial samples of plankton were collected in Acapulco Bay,
using 150-μm mesh net, with the objective of studying the temporal variation in
the abundance, species composition of the copepod community, and their
relationship with some environmental parameters. Twenty-nine species of four orders
were identified: 11 of Calanoida, 4 of Cyclopoida, 3 of Harpacticoida and 11 of
Poecilostomatoida. A multivariate analysis (PCA) used to detect association
between the abundance of copepod populations, and the environmental conditions
through time, indicates a marked effect of the temperature and salinity
parameters, on the abundance of the four copepod groups. The calanoids
dominated numerically during most of the sampling months. The more important
copepods genus wereCorycaeus(7 species), andOithona(4 species). Nevertheless that the
abundance of all copepod groups was affected temporarily by variations in the
environmental conditions, the species composition inside the copepods community
remained very stable.
