Résumé en anglais |
The dynamics and growth of Owenia fusiformis juveniles were studied over a period of three months under different edaphic conditions in the eastern part of the Bay of Seine. Post-larval settlement was synchronous and showed the same high densities in different communities with or without adult populations. There was a rapid disappearance at the juvenile stage in the unfavourable bottoms. The distribution of the juveniles was gregarious. Growth was slow during the first month ; it was also highly variable. Growth differences were observed between stations: growth was higher in the station located just seaward of the Seine estuary. The relationships between edaphism, recruitment and growth of juveniles are discussed in relation to the changes in space and time of Owenia fusiformis Population from the eastern part of the Bay of Seine. |
