| The black-lip pearl oyster Pinctada margaritifera lives and reproduces with high performance in most of Tuamotu Lagoons. Technics to collect spats, to culture juveniles and to operate oysters were quickly found and applicated. Nevertheless, the sudden rise of this activity has been correlated with an anarchic development. For instance, large occupation of areas in the lagoons, cultivation of numerous oysters in confined areas, lack of knowledge on the basis culture technics in many farms. In 1985, mass mortalities have appeared in some lagoons and 50 to 80% of cultured stock died. Some investigations have been done but no explanation was found. In 1988, the mortalities are still very high. An analysis of cooperative production results from 1979 to 1988... |

| The paper presents a state of the art on knowledge of the black pearl oyster aquaculture at the scale of French Polynesia. It also introduces the main results obtained throughout the multi-partners POLYPERL project. The goal of this project was to develop an integrated and participative action-research of the pearl oyster culture system, focusing on the environmental, technological, economical and societal dimensions impacting the industry. The research proposed ranges from the understanding of biological phenomena of the production system to socio-economic aspects and governance of the industry, taking into account the management of anthropogenic, climate and health risks. We introduce here the different papers from the POLYPERL project that are compiled... |

| Growth of the black-lip pearl oyster, Pinctada margaritifera var. cumingi, was studied for an annual cycle, from March 1997 to April 1998, in the lagoon of Takapoto atoll (Tuamotu archipelago, French Polynesia). Growth in shell and in tissue were measured every 15 days on three successive age groups of cultivated pearl oysters. At the same time, hydrobiological parameters (temperature, salinity, oxygen concentration, suspended particulate matter), known to have influence on bivalve growth, were followed each week during culture. No seasonal trend was observed in hydrobiological parameters, except for temperature which varied between 26 degrees C and 31 degrees C. The potential food for pearl oysters (particulate organic matter, POM, mg l(-1)) was slightly... |
