The role of macroinvertebrates in diets of fish in River Dambovita, Romania

Abstract

eomposition ofthe food speetrum and feeding behavior in fish in Romania have not been previously well researehed (BANARESCU 1964). We studied fish living in the River Dambovita and its tributaries to determine their eommunity strueture and feeding habits in areas with varying anthropogenic impact and natural features. We ana1yzed food eomposition and feeding behavior o f the fish speeies eaptured aeross an altitudinal gradient and in eonjunction with the anthropogenie influenee, mainly pollution. The 14 si tes were loeated at GPS coordinates 44.28671-45.25130 N; 25.08115-26.07982E (Fig. 1).
