Comparison of defense reaction of Rasbora paviei (Cyprinidae) from different habitats

Abstract

Experimental investigation of defensive behavior of Rasbora paviei Tirant, 1885 from riverine and limnetic habitats was carried out. Fish for the experiment were caught in the upper stream of Cai river and shallow littoral of Cam Lam reservoir of Khanh Hoa province of Central Vietnam. Billfish Lepisosteus sp. was used as a model predator for the experiment. Distinctions in defensive reaction of R. paviei from different ecological conditions were found. It was revealed that defensive behavior of fish from river’s upper stream was more effective than that of fish from the shallow littoral zone of the reservoir.
