Empirical modelling of the growth of Ruditapes philippinarum by means of non linear regression on factorial coordinates

Abstract

In order to highlight the main factors accounting for the growth of clams in Marennes-Oléron Bay, three locations were investigated in 1984-85. 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. © 1988 IFREMER-Gauthier-Villars.
