| A study of pearl oysters Pinctada margaritifera growth and mortality was done on a monthly basis between June 1990 and September 1991 in Takapoto atoll (Tuamotu archipelago). Meanwhile, sampling parameters representative of bivalves food showed a remarquable spatial stability whithin the lagoon. The amplitude of temporal variability varied in the order of some days. Carrying capacity appears low : energetic content of particulate material in waters is about 2 joules/liter, ten times lower than in temperate areas. On the opposite, seasonal effect is reduced and particulate food is always available. Oysters rearing conditions were appropriate during the studied period with a low mortality rate and a regular growth in size (from 97 mm to 136 mm). Pearls... |
