摘要: Over the last decade there has been considerable growth in marine mammal-watching tourism throughout world. Due to species use of coastal habitats, bottlenose dolphins are most frequently exposed dolphin-watching tourism. We conducted boat-based focal follows schools determine effect boats on dolphin behaviour. A CATMOD analysis showed that behaviour differed by boat number, particular, resting decreased as number increased. Dolphins rested less and engaged more milling presence permitted compared non-permitted boats. An increase from 49 70 trips per week a change their departure times resulted further decrease Currently effects boats, particular whilst they Bay Islands, substantial. In light these findings we suggest current legislation New Zealand is not affording this isolated population protection disturbance.
