The study of the trophic relations needs to collect data which can best represent the variability of the populations of molluscan and the parameters of the water. For the water, the main parameters which play a role on the production of molluscan in an estuarine area are the temperature, the seston, and the phytoplanctonic biomass. For the temperature is proposed to sample only twice a month. At the contrary for seston variations which are very large on a tidal cycle and correlated with the currents and the waves, it is necessary to take in count this variability. For the phytoplancton, the annual cycle is well characterized, but the variability at a station is depending on the caracteristic of each water masses. The authors suggest that a sampling... |

The purpose of this study is to examine the Polychaetes populations of the mussel Mytilus galloprovincialis Lamarck 1819 assemblage in Thessaloniki Bay (Perea, Neoi Epivates, Agia Triada) in space and time. Forty-eight Polychaetes species, which belong to 16 families, were identified among 10 593 individuals. The different distribution in space and time can be attributed to the life cycles of the Polychaetes, and also to the various biotic interactions. In general, the abundance follows the succession of the seasons, with some deviations though. Thus, the samples can be divided into two major groups, the winter and summer samples. The structure of the feeding guilds of the Polycheates population was also investigated and 9 different feeding guilds were... |
