The Capture
-
Many dolphins have been killed or seriously injured during this violent procedure. 50% have died in some captures.
-
Mothers have been taken from their babies in some captures and seriously injured or killed in others, creating a clear and present danger and for its baby.
-
Capture may remove key individuals from the dolphin society threatening its integrity and survival.
-
Capture causes sever mental and physical stress on dolphins.
-
Dolphins are transported to holding facilities by boat, truck, and planes. This is very terrifying since none of this is part of its reality.
-
Transport is also quite painful as they loose body heat around their flippers, dorsal fins, and tail, and experience the effects of gravity for the first time.
-
Enclosures
-
Tanks or pools are made of concrete or steel, which are static and impoverished in comparison to the sea.
-
Federal law requires holding tanks to be 24 ft. X 24 ft., and six ft, deep or half the body length of the dolphin which ever is greater. Tanks can be smaller if rectangular.
-
Tanks are filled with artificial sea-water treated with chlorine, ozone or both.
-
Tanks are stocked with captured dolphin, rehabilitated stranded dolphins or captive born dolphins.
-
Captive Environment
-
Dolphins are forced to swim in endless circles until they die.
-
Everything about captivity is unnatural for dolphins: water, food enclosures, sounds, use of sonar, social structure, behavior even causes of deaths.
-
Dolphins in captivity are forced to live in worlds governed by fear dominance and aggression, like our federal penitentiaries.
-
Government records show only 53% of captured adult dolphins survive the first 90 days in captivity. Survivors live on average an additional 6 years.
-
Half of captive dolphins in North America die every seven years.
-
As of Jan. 1999, the average stay of a dolphin in captivity according to government records (1972 -1999) is approx. 7 yr.
-
Captive Born
-
A high percentage of captive born dolphins are stillbirths or premature.
-
Captive born dolphins rarely lives to reach puberty.
-
Dolphins born in captivity are often taken from their mothers. They sometimes kill their own babies. This is maladapted behavior.
-
Training
-
Dolphins are trained by food deprivation and then using food as a reward for obeying the commands of the trainer.
-
Husbandry
-
Captive dolphins are routinely given Maalox and Tagamet to treat gastric bleeding ulcers brought on by stress.
-
Captive dolphins are given anti-depressants to help cope with the extreme mental and physical stress of captivity.
-
Because dolphins are forced to survive in crowded enclosed areas in their own waste, they are vaccinated against many diseases.
-
Dolphins are often treated for serious skin problems and severe eye irritation from chemicals added to the artificial sea-water.
-
To prevent obesity, captive dolphins are fed only 20lbs of fish per day. Since they are less active they don't require as much.
-
Causes of Deaths
-
Captive dolphins have died from the following: Accidental drowning, suffocation, vaccine rejection, fracture skulls, multiple organ failure, chlorine poisoning, heart ruptures, aggression, ingestion of foreign objects, pneumonia and possible suicides.
