Effects of the Composition of Marine Particulate Matter on Selection Efficiency and Oxygen Consumption Rate of the Pearl Oysters Pinctada fucata martensii

In the report, in order to illustrate the relation between the food selection efficiency and oxygen consumption rate of the pearl oysters Pinctada fucata martensii and the composition of marine particulate matter, the natural sea area constant water method was performed to analyze the physiological energy characteristics of the P.fucata martensii and the composition of marine particulate matter.The results indicated that there are no significant correlation between the filtration rate (FR) and the composition of marine particulate matter (P>0.05); there are very significant correlation between selection efficiency (SE) and the particulate organic matter (POM), SE and the feed quality of marine particulate matter (f) (r=0.500,P=0.000; r=0.505,P=0.000); there are very significant correlation between oxygen consumption rate (OCR) and POM, OCR and f (r=0.268, P=0.000; r=0.319, P=0.000).These findings suggested that with the increase of f, the food selection efficiency and digestive strength of the P.fucata martensii were enhanced.
