The study was performed in June–August 1993, in eighteenenclosures (1 × 2 m) built in a fertile, small (area2.5 ha) and shallow (max. depth 1.7 m) lake, Little Mere(north-western England). Three densities of Nuphar lutealeaves were manipulated in enclosures to 10%, 50% and90%coverage of the water surface. Perch (total length ca. 15 cm)wasstocked in half of the enclosures in a density 3 fishm−2. Thevertical distribution of Chironomus f.l. plumosuslarvae (classified in the size classes: 0–5, 5–10… CONTINUE READING
