Publication Abstract

A comparison of adjacent natural and channelised stretches of a lowland river

M. Pilcher, G.H. Copp and V. Szomolai

Comparisons of fish assemblages of adjacent stretches of natural and channelised river are rare. We compared the species richness, ichthyomass (kg) and fish density in ten pairs of adjacent stretches on the the River Lee (Hertfordshire, UK) and River Stort (Essex, UK) to assess the influence of channelisation on fish community structure. Significantly lower values (paired t-test) for all aspects were found in the channelised stretches compared to the natural stretches.
