| The monitoring of the reproduction of Crassostrea gigas, and more occasionally that of the mussel Mytilus edulis, is carried out in the Marennes-Oléron Basin, each year, from June through to September. This report presents the main results obtained in 1997, 1998, 1999, 2000 and compares them. It also recalls the techniques used and provides, in appendix, some bibliographic information on larval development. |

| The Marennes-Oléron is a well known cupped oyster (Crassostrea gigas) and mussel (Mytilus edulis) reproduction area. Every year, a monitoring of the reproduction of these two species is carried out on behalf of the Regional Shellfish Culture Section of Marennes-Oléron. This monitoring aims to determine the periods of larval emission in order to let the professionals know about the best collection times This study presents the main results obtained in 1999 and compares them with those obtained in 1997 and 1998. The year 1999 showed good results as far as larval emission and development are concerned in both oysters and mussels. The comparison of the three consecutive years shows the disparity of larval evolutions. |

| The microbiological classification of the Marennes-Oléron shellfish farming area (according to Council Directive 91/492/EEC) let appear sorne periodically polluted spots. A research of the potentiel sources has been conducted around these spots. Twelve points were sampled during a year with faecal coliforms and streptococcus contamination level in water (and shellfich when possible). Several microbiological pollution sources were found, in the Seudre estuary (umstream) and in Oléron island : lack of, or ineffective sewage systems, cattle farming without convenient manure treatrrtent, and so on .. Recommendations are given to improve this situation. |

| Monitoring of reproduction in the oyster Crassostrea gigas, and more particularly in the mussel Mytilis edulis were conducted, in the Marennes-Oléron Bay each year, from June to September. This report gives the main results obtained in 1997, 1998, 1999,2000 and compares the results between years. It also summarises the fishing techniques used and gives information on larval development in the annexes. NOT CONTROLLED OCR |
