| Studied the effect of the predation of Noctiluca scintillans, Sagitta friderici and larvae of Engraulis anchoita in planktonic community of the coastal waters off Buenos Aires province from samples obtained of a permanent station EPEA (38°28’ S, 57°41’ W, 48 m depth) from March 2000 through April 2001. The composition of the diet of the three species predators considering appearances quantitative and qualitative was determined. It found that N. scintillans consumed mainly diatoms and copepod eggs. The alimentary index varied between 27.50% and 77.00%. The highest value corresponded to September, 2000. The analyses of the diets of S. friderici and of the larvae of E. anchoita indicated that both consume mainly different stages of development of the same... |
