Invertebrate Drift in a Mountain Stream in Norway By J. &'I. Elliott Dept. of Zoology, University of Exeter Present address: Freshwater Biological Association. Ambleside, England In August 1964 drift was sampled in a small mountain stream (300 metres above sea level) on a north facing slope. The stream consists of short runs and waterfalls, finally entering the river Lo at the east end of the Nordfjord. Sampling was by means of a small net (15.5 meshes per cm) which floated on the surface of the water and sampled to a depth of 8 cms, with a total sampling area of 100 sq. cms. The net was placed in a run with an average velocity of 90 cm per sec., and thus strained 194,400 litres per 6 hours. Over a periocl of 24 hours, the net was emptied every 6 hours to give a total of four samples. As sampling started at 1700 h. (Norwegian summer time), the second sample from 2300 h. to 500h. coincided with night (sunset c. 2230h. and sunrise c. 530h.) Table 1. Numbers of aninzals in each drift sanzple.
