✦ Synopsis

The fauna was sampled regularly by sweeping with a net, by means of a quantitative sampler and in mats of artificial Littorella. The three methods were found to be complementary. Only the second yielded reliable quantitative data, but it was the most time-consuming. The artificial-vegetation method was the quickest, and comparable samples could be taken regularly without harm to the environment. A few species were not attracted to the artificial vegetation. The net revealed that some species were more abundant in certain species of plant than in others. The artificial vegetation was particularly suitable for sampling in deep water. Moreover it captured the smallest specimens, which could pass through the sweep-net because the mats could be brought up inside a net of finer mesh.
