Despite no diagnosis, captive dolphin is on antibiotics

The manager of New Zealand's only marine zoo is concerned about the health of one of its two remaining dolphins.Gary McDonald, from Marineland in Napier, says 38-year-old Shona has been unwell for more than a fortnight.He says she has been eating very little and is lethargic.

Mr McDonald says a variety of veterinary tests have failed to show up any abnormalities, but the dolphin is on antibiotics as a precautionary measure.He says Shona and the other dolphin, 36-year-old Kelly, hold the key to the future of Marineland in its present form.
