Abstract

Carnal vulnerability is a powerful yet underutilised tool in integrated pest management. The lack of species-specific knowledge of underpinning sexual drivers and mechanisms for their detection has precluded efficient exploitation of the vulnerability. As a step in understanding how mature common carp Cyprinus carpio communicate and attract conspecifics, the present study undertook anatomical and histological examinations of the olfactory system, tracing changes in crypt receptor neurons (CRNs) within the olfactory rosette in relation to gonadal development, as proxy. Quantification of the density and relative position of CRNs in the lamellae revealed that their density increases significantly with sexual maturity in both males and females (P P C. carpio, to carnal lure and capture that could be exploited in pest management programs.
