11.The"swim-with-dolphins"tourist industry is becoming more popular every year.After all,it can cost a large amount of money to have this kind of holiday experience.So tour operators try to place eager swimmers as near as possible to the dolphins.Research has shown that dolphins do not like it at all if the swimmers slip into the water directly on top of them or if humans are in their path of travel.However,if swimmers enter the water to one side of them,the dolphins do not avoid the swimmers to the same extent.
In all cases,the dolphins seem to have become more sensitive to the presence of the swimmers.For dolphins,swimming amongst or with humans is not necessarily a high priority.This study has shown that only 19% of any group of dolphins will participate in interaction.Young dolphins are the most likely to interact.It is believed that they see humans as"entertainment"and that the interaction is a new and unusual experience for them.
It is frequently asked whether"swim-with-dolphins"tourism should be discontinued.The advice is that dolphins should be given enough periods of time throughout the day when they are not exposed to tourism.Permitted interactions should not be too disturbing to the dolphins since there could be mothers and calves (幼崽) present in dolphin groups.There should also be educational campaigns about the creatures and what is likely to cause danger to them.
It is not easy to explain to someone that they cannot fulfill their lifelong dreams because the dolphins are resting,or that a mother dolphin and calf are in the area.But if we are to enjoy these remarkable animals and not just use them for our entertainment,then we must carefully monitor the"swim-with-dolphins"industry worldwide.
