Habitats of 0+ fry in an English lowland river.
Original language description
The fish fry communities of the upper River Thames and a connected backwater were sampled quantitatively by a fry seine. The following main habitat types were samled: (1) clumps of channel plants at the water edge of the littoral vegetation and (2) deeperosion banks without plants. A third characteristic habitat in this river were (3) shallow organically-rich sandy-gravel beaches produced by watering cattle. The most species-rich and abundant fry communities were found in habitats with a plant cover and in the shallow beaches because they offered both a good food resource and protection from predation. Neither of these was available in the deep erosion banks where few 0+ fish occurred. No 0+ fry occupied the plantless sites in the backwater which weresubject to high velocities. Roach was the predominant species in the abundant fry communities and its relative abundance explained differences in community structure estimated by Simpson's and Shannon Diversity Indices.
