Abstract
The apparatus allows the sampling of both algal and animal components of the epiphyton. It consists of a perspex tube, 100 cm long with an internal diameter of 4 cm, and of an epiphytic sieve. The latter is made of two 2.5 cm cross-sections of perspex tubing with a piece of circular mesh glued between them. While sampling, a randomly chosen shoot is isolated from the ambient water by means of the tube, cut at the bottom sediment and removed together with epiphyton. The water, taken together with the shoot is then removed using the epiphytic sieve, joined with the tube under the water surface. The detached organisms, associated with the stem and those scraped from the stem with a stiff brush afterwards, concentrate on the mesh.
