CYCLOPOID COPEPODS

open access: yesJournal of the American Mosquito Control Association, 2007
Cyclopoid copepods have proved more effective for practical mosquito control than any other invertebrate predator of mosquito larvae. Their operational potential is enhanced by the fact that mass production is relatively easy and inexpensive. The exceptional potential of copepods for mosquito control was first realized about 25 years ago.

Effect of supplying four copepod densities (Acartia sp. and Calanus pacificus) onthe productive response of Litopenaeus vannamei pregrown intensively at microcosm level

open access: yesCiencias Marinas, 2011
A seven-week experiment was performed to evaluate the effect of supplying copepods (Acartia sp. and Calanus pacificus), as exogenous feed during the intensive pre-growout phase of white shrimp (Litopenaeus vannamei), on the productive parameters and ...

Ectoparasitic copepod infestation on a wild population of Neotropical catfish Sciades herzbergii Bloch, 1794: Histological evidences of lesions on host

open access: yesInternational Journal for Parasitology: Parasites and Wildlife, 2017
We analyzed the infestation of the attached copepod species Lepeophtheirus sp on a wild population of Sciades herzbergii. The infestation and occurrence of attached copepods were related to body size, maturity and sex of host and the presence of lesions ...

Biological responses to change in Antarctic sea ice habitats

open access: yesFrontiers in Ecology and Evolution, 2023
Sea ice is a key habitat in the high latitude Southern Ocean and is predicted to change in its extent, thickness and duration in coming decades. The sea-ice cover is instrumental in mediating ocean–atmosphere exchanges and provides an important substrate

Spatial and inter-annual variability of proto- and metazooplankton during summer around the Kneiss Islands (Tunisia, Central Mediterranean Sea)

open access: yesApplied Water Science, 2018
We studied the distribution of proto- and metazooplankton coupled with environmental factors in the coast area around Kneiss Islands (Central Mediterranean Sea). Zooplanktonic communities were sampled during summer 2009 and summer 2010 at three stations.
