Abstract:

A pair of zebra sharks (Stegostoma fasciatum) successfully reproduced in the Shark Reef exhibit, Henry Doorly Zoo. Mating behavior was similar to that described for the nurse shark (Ginglymostoma cirratum) (Klimley, 1980; Carrier et al., 1994) and chain dogfish (Scyliorhinus retifer) (Castro et al., 1988). Between September 1998 and September 2000, 80 fertile eggs were laid. Mean incubation time was 152.5±26.5 days, newborns had a mean TL of 30.2±0.8 cm, and mean weight of 92.2±14.0 grams. Increased water temperature resulted in decreased incubation time (R2=0.887, n=6).
