Influence of plankton concentration on gametogenesis and spawning of the black lip pearl oyster Pinctada margaritifera in Ahe atoll lagoon (Tuamotu Archipelago, French polynesia).
Pearl culture industry represents one of the dominant business sector of French Polynesia. However, it still entirely relies on unpredictable spat collection success. Our aim was to assess the influence of natural plankton concentration fluctuations on maturation and spawning of the black lip pearl oyster Pinctada margaritifera, during a 4 months survey conducted in Ahe atoll lagoon. Plankton c...
متن کاملPearl oysters Pinctada margaritifera grazing on natural plankton in Ahe atoll lagoon (Tuamotu Archipelago, French Polynesia).
In atoll lagoons of French Polynesia, growth and reproduction of pearl oysters are mainly driven by plankton concentration. However, the actual diet of black-lip pearl oysters Pinctada margaritifera in these lagoons is poorly known. To fill this gap, we used the flow through chamber method to measure clearance rates of P. margaritifera in Ahe atoll lagoon (Tuamotu Archipelago, French Polynesia)...
متن کاملEvaluation of selected substrates for collection of hatchery reared black-lip pearl oyster (Pinctada margaritifera) spat
An experiment was conducted to investigate the effect of collector materials and position on Pinctada margaritifera spat attachment. Settlement on polyethylene pipes (54.6%) was significantly higher (P < 0.05) than on plastic baskets (25%). Significantly higher (P < 0.05) spat catch was recorded from the collectors which were installed on lower height of settlement tank than upper. The number o...
