Determination of Gender in the Pearl Oyster Pinctada margaritifera
The pearl industry in French Polynesia is based on exploitation of natural stocks of the blacklip pearl oyster (Pinctada margaritifera). It generates an annual turnover of €90 million. Improvements in pearl quality need genetic studies to improve the populations. This pearl oyster is a protandric species, in which the sex ratio normally is biased toward males. There is an increasing interest in...
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...

متن کاملGrowth of blacklip pearl oyster Pinctada / margaritifera juveniles using different nursery culture techniques
Ž . This study was based on blacklip pearl oyster Pinctada margaritifera juveniles, that were hatchery-reared and 8 months old. They were held for 5 months in suspended culture using five Ž . culture techniques: in 24-pocket juvenile panel nets PN24 ; enclosed within 5-mm plastic mesh Ž . ‘inserts’ placed in the pockets of eight-pocket adult panel nets PN8 ; in 5-mm plastic mesh inserts Ž . Ž ....
متن کاملTemperature and Food Influence Shell Growth and Mantle Gene Expression of Shell Matrix Proteins in the Pearl Oyster Pinctada margaritifera
In this study, we analyzed the combined effect of microalgal concentration and temperature on the shell growth of the bivalve Pinctada margaritifera and the molecular mechanisms underlying this biomineralization process. Shell growth was measured after two months of rearing in experimental conditions, using calcein staining of the calcified structures. Molecular mechanisms were studied though t...
