Description 430-441
Clownfishes Amphiprion sebae, A. clarkii, A. percula, A. ocellaris and Premnas
biaculeatus were reared in captive condition and their parental care
activities were studied.  Role of both
male and female in parental care and terminating in successful hatching of eggs
studied is described. Site selection, clutch formation, spawning, guarding,
mouthing and fanning of the eggs were quantified. A. sebae exhibits more effective parental care for longer
durations. The time spent on fanning was longer in A. sebae and shorter in A.
clarkii.  Fanning frequency was
higher in A. percula but lower in A. clarkii. In the five species the
fanning duration and frequency were positively correlated to hatching success.
Gradation of dissolved oxygen levels adjacent to the clutch area due to the fanning
behavior is discussed.  Relation between
body weight and the fecundity, fanning duration and frequency with hatching
success are documented.
