摘要根据两个地点的底质样品，对厄勒海峡11种双壳类的沉积进行了定量研究。溅落的时间和沉降标本的数量与浮游生物中幼虫发生的现有数据有关。计算了每平方米沉降样品的数量，该数量的减少和双壳类在飞溅后的第一个月内的生长。厄勒海峡的增长率似乎比大多数其他温带地区要小。这种差异的可能原因进行了讨论，并建议，一些结果先前记录在文献中的新解决的双壳类的增长是不准确的采样筛分技术不充分的帐户。通过对两个地点同一种贝类的定殖标本数量的比较，证实了双壳类幼体在自然界中能够对定殖地点进行选择。在第一个月期间，吐口水的数量大幅减少的原因...
Abstract The quantitative aspects of the settling of 11 bivalve species were registered in the Oresund, based on bottom samples from two localities. The time of spatfall and the numbers of settling specimens were related to existing data on occurrence of larvae in the plankton. The number per m2 of settling specimens, the decrease of this number and the growth of the bivalves during the first months after spatfall were calculated. The growth rate in the Oresund seems to be smaller than in most other temperate areas. The possible reasons for this discrepancy are discussed and it is suggested that some of the results previously recorded in the literature on growth of newly settled bivalves are inaccurate on account of inadequate sampling-sieving techniques. By comparing the number of settling specimens of the same species in the two localities it was confirmed that bivalve larvae are able to make a choice of settling place in nature. Causes of the heavy decrease in number of spat during the first months aft...
