Publication Abstract

Diel densities of young-of-the-year fishes in the River Lee (Hertfordshire) over a 24-h period in late summer

L. Vilizzi and G.H. Copp*

Data on the diel density and dispersal of young-of-the-year (0+) fishes in the River Lee (Hertfordshire) at Holwell Bridge were examined in August 1998 to determine whether patterns in this stretch with no fencing along the banks were similar to those observed in August 1996 in a nearby, downstream stretch (Woolmers Park), where the river is fenced off. Although the numbers of 0+ fish captured (both overall and for most fish species) was higher at night or dawn, similar to Woolmers Park, the differences were not statistically significant, probably due to low sample number.
