青岛多齿围沙蚕的生产量

A P erinereis nuntia (Polychaeta: Nereidaepopulation inhabiting a cobble-sand beach in Qingdao has been studied over one year to estimate its production. This population reproduces from March to August with a peak in May, June and July. Total numbers vary between 49 and 3670 individuals/m2. Total standing stock(Ash-free dry weight) lies between 12.4 to 18680.6mg/m2, with a mean of 6632.0mg/m2.Production was calculated by determinating the weight-specific growth -rate of the 20 size-classes in each of the 3 year groups. Production (AFDW) in the year Mar., 1989-Feb., 1990 was equal to 35.59 g/m2. P:B ratio was equal to 3.62.
