Protect Dolphins from Captivity In the Turks and Caicos Islands A proposal to build a captive dolphin facil-ity on Grand Turk for the entertainment of tourists is being considered. The keep-ing of captive dolphins should be consid-ered counter to the Turks & Caicos Islands “Beautiful by Nature” slogan. Dolphins are complex and highly intel-ligent animals. Some characteristics that make dolphins more like humans than other animals are: • They exhibit complex behavioural, cognitive and social traits. • The brains of dolphins are highly de-veloped and larger than humans. • They have clearly demonstrated the ability to understand how diﬀerent things function and how to understand combi-nations of complex instructions. • They have highly developed commu-nication skills. • Dolphins experience emotions much like humans. What happens to these highly intelli-gent, social animals when they are kept in captivity? Many of their natural skills and attributes begin to change. Dolphins during the capture process suﬀer tremendous trauma and stress. There is a six-fold increase in the mortal-ity rate of dolphins captured from the wild in the ﬁrst ﬁve days after capture. In fact, this increase in stress mortality hap-pens each time a dolphin is transported. Given the conﬁned space of all captive habitats in which dolphins are held, physi-cal activity is greatly reduced. Sea pens (fenced oﬀ portions of open seawater or lagoons) are thought to be better, but even the largest sea pens greatly reduce the space available for the dolphins. They also generally don’t provide protection for the animals from hazards such as hur-ricanes, potential pollutants from the land, and potential exposure from human waste. Wild dolphins catch their food, which consists of live ﬁsh. Captive dolphins must be taught to eat dead ﬁsh which is lower in nutritional value. Dolphins swimming free.

Dolphin communication skills change, or don’t develop as they would in the wild. The vocalisations decrease in diver-sity and new vocalisations are learned, often imitating noises found in their new environment. Dolphinaria operators cite the fact that lifespans in captive facilities is com-parable to that found in the wild. There is no increase in lifespan for captive dol-phins and there is continuing debate about whether lifespans in captivity are actually worse. The health of dolphins in captivity is also a challenge to monitor. The lack of mobile facial expressions (the “smile” on their face is a ﬁxed, unchanging expres-sion) makes it diﬃcult to identify animals in physical distress. Most often the ﬁrst sign of a problem is a lack of eating with dolphins often dying within a day or two of this observation. Captive dolphin programs require dol-phins. Captive breeding programs do not generate enough dolphins to fulﬁll the de-mand from new and existing dolphinaria. This means more dolphins must be cap-tured from the wild and the methods used to capture dolphins are traumatic and lead to many dolphin deaths. Swim with dolphin programs provide no educational beneﬁts, they merely ex-ploit the animals while exposing them to additional risks, such as increased stress related to too much exposure to humans, increased exposure to health hazards and health risks from inadvertent or inten-tional touching of sensitive areas such as the blowhole and eyes. Humans also are at risk during these programs from ag-gressive behaviour from the animals. Bottom line, captive dolphins are much like captive humans or slaves. This is not an attraction that is com-patible with the “Beautiful by Nature” Turks and Caicos Islands, and only harms the eco-friendly image of this country.
