Contribution à l'étude de faisabilité d'une usine marémotrice dans le Golfe normano-breton - Zooplanctonologie halieutique ArchiMer
Martin, Jocelyne; Halgand, Daniel.
Zooplankton study presented in this paper, is one of the three parts of fish ecology study undertaken by IFREMER in 1983 on Electricité de France request. The present work draws up an inventory of young stages from meroplanktonic species (fish eggs and larvae, crustacean larvae and postlarvae) in the area studied (a part of gulf of St Malo) together with rather large holoplanktonic organisms. Sampling period (from March to September) and periodicity were choosen according to study of hatching area and period of economical crustaceans. An hydrological study was carried out in the same time.

Long-term series in ichthyoplankton: Sole and sprat at French coast of the North Sea from 1975 to 1994 ArchiMer
Woehrling, Daniel; Le Fevre-lehoerff, Geneviève.
The sampling of eggs and larvae of sole and sprat at Gravelines (French part of the North Sea coast) since 1975 has produced a long-term series showing major interannual changes, Comparison of the results obtained on two species, one benthic and the other one pelagic, suggests some events affecting the environment that are also revealed by the holoplanktonic (appendicularia, chaetognatha) and meroplanktonic (cirripeda larvae) compartment. This Study attempts also to distinguish general variations from more closely species-related fluctuations.

Variabilité mensuelle du zooplancton et de l'ichtyoplancton dans le golfe deTunis OceanDocs
Zarrad, R.; El Abed, A.; Missaoui, H.; M’rabet, R.; Romdhane, M.S.; Jarboui, O..
Monthly variability of zooplankton and ichthyoplankton abundance and composition were studied in 6 stations in the Gulf of Tunis between February 2003 and January 2004. Plankton trawls were horizontal, in surface and at night. Study area seems to be influenced by climatic conditions and the outflow of Majreda River that affect the surface temperature and salinity. Copepods, with many abundance picks in the year, formed the most abundant group (84%) followed by cladocerans (8%) and chaetognaths (3%). The swarms of appendicularians, cladocerans and medusas then for zoe are in spring. The highest fish spawning periods was in summer then the highest larva abundance was in winter and summer.
