| The growth and reproductive cycle of cultured black-lipped pearl oysters, Pinctada margaritifera (L.), were studied in the Gambier Islands (134°52' W, 23°07' S) from September 2002 to August 2003. Temperatures were recorded throughout the year, revealing seasonal temperature variations between 22.3 °C and 27.8 °C. The mean annual chlorophyll a value, as computed from satellite data, was 0.188 ± 0.075 µg L-1. To study growth and reproduction, 720 two-year-old individuals were ear hung on longlines suspended at a depth of 7 m. Samples were taken twice a month to obtain the following measurements: shell height; wet weight of flesh and total oyster; dry weight of adductor muscle, mantle and visceral mass; and glycogen content. Gonad development was also... |
