Hypothalamic-Hypophysis-Gonad is the main neural-hormonal axis regulating fish reproduction. Such axis may be affected by male-female interactions stimulating physiological responses (as hormonal releasing and gonad development) and behavioral responses (as courtship, chasing and spawning) among the interacting animals. Thus, visual and chemical communication between opposite sex may modulate fish reproduction. This study checked the effect of visual and chemical male-female interaction in the Nile tilapia. Thus, fourteen couples were studied in four different conditions of communication: 1) only visual contact; 2) only chemical contact; 3) chemical and visual contact; 4) no sensorial contact (isolated). The reproductive behavior and gonad ...
