  1. Breed marine and freshwater mammals in captivity

    A study in 1993–2003 at a marine park in Hong Kong (Brook & Kinoshita 2005) found that during a controlled captive-breeding programme, four of six female Indo-Pacific dolphins Tursiops aduncus successfully conceived and gave birth to nine calves, seven of which survived. Four of six female dolphins successfully conceived in captivity and gave birth to a total of nine live-born calves (1–3 calves each). One other female mated but did not conceive, and one female conceived but the calf was stillborn. Seven of the nine live-born calves survived (length of time not reported) and were considered healthy. The other two calves died within 1–3 days due to lung infections or trauma caused by the mother. On 11 occasions in 1993–2003, one of six ovulating female dolphins (aged 10–25 years) was placed in a pool with one of five male dolphins (aged 10–31 years). Male and female dolphins were housed separately at all other times. Ultrasound was used to predict the timing of ovulation and to monitor each of the 10 pregnancies during gestation periods of 349–382 days.
