Última Fluctuations d'abondance de l'ichtyoplancton sur une zone frontale cotiere (Golfe de Gascogne: Baie d'Audierne) ArchiMer Camus, Patrick; Delpech, Jean-paul; Omnes, Marie-helene; Mastail, Max. A two years ichthyoplankton sampling program over an eight station network on each side of a coastal tidal front was conducted twice a month during neap tides. A principal component analysis was performed on the data (taxa and observations) which were segregated during the summer into two groups of taxa related to two groups of stations belonging to two different hydrodynamical areas. In July and August 1980 during a tide cycle, zooplankton was investigated at two stations in the stratified and transitional area. Periodic fluctuations of meroplanktonic taxa correlated to the movement of the front induced by the tide were observed.

In order to highlight the main factors accounting for the growth of clams in Marennes Oleron Bay, three locations were investigated in 1984-1985. First, factor analysis provided information on fluctuations of the environment. Second, principal components analysis was used to study ecological phenomena. The main axes explained the growth rate, which was included in an allometric model. Its properties were then studied by means of sensitivity analysis.
