The lipid class composition in juveniles of the mussel Mytilus galloprovincialis of rocky shore
and subtidal origin were compared after transfer to a subtidal environment in the Ria de Arousa
(northwest Spain). The experiment was conducted between November 27, 1995 and July 3, 1996. In
addition to mussel origin, the influence of the different environmental parameters on the changes in
lipid classes was studied. At the start of the experimental period, only the relative percentage of the
triacylglycerols (energetic function) was significantly higher in the subtidal specimens. However,
when the initial absolute contents were examined, the phospholipids and sterols were also
significantly higher in this mussel group. Differences in the relative percentages of phospholipids
and sterols were maintained until day 22 of the experiment. Our results show that during the first 36
days of the experimental period the mussel origin participated significantly in the model explaining
the variance of triacylglycerols, phospholipids and sterols. These results suggest the initial
differences in content and relative percentages of the lipid classes studied are possibly linked to the
contrasting environmental conditions in which the two mussel groups had previously developed
(subtidal and rocky shore habitats). In contrast, 50 days into the experiment the origin term did not
participate in the model of variance of these lipid classes. These results in turn suggest that during the
course of the investigation the mussel seeds of rocky shore origin were able to exploit the available
food resources in the subtidal habitat. Based on these results, the influence of mussel origin and environmental parameters on the changes in lipid classes of both mussel groups is discussed.
