I. Tatrai et A. Herzig, EFFECT OF HABITAT STRUCTURE ON THE FEEDING EFFICIENCY OF YOUNG STAGESOF RAZOR FISH (PELECUS-CULTRATUS (L)) - AN EXPERIMENTAL APPROACH, Hydrobiologia, 299(1), 1995, pp. 75-81
The effects of a submerged macrophyte (Potamogeton pectinatus), turbid
ity (produced by 50 mg l(-1) kaolin), and their combination on the fee
ding rate of young razor fish (Pelecus cultratus (L.)) were studied in
the laboratory. Young razor fish showed preference for Copepoda in mo
st of the simulated habitats. Razor fish fed more efficiently in the a
bsence of any environmental structure, but the more structured habitat
s, 3 g wet wt l(-1) of simulated submerged macrophyte and turbidity co
mbined with vegetation, had a negative impact on food consumption rate
s.
