Keeping Marine Mammals in Captivity sample essay
Does captivity affect the overall health and behavior of marine mammals?
Habitat: Open ocean
Habitat: Tank of ocean water, replicated to appear like the ocean. Diet: Krill caught in the ocean, fed three times a day.
Behavior: Friendly to other mammals within the tank.
If we keep marine animals in captivity for over a year, then their health and behavior will be negatively impacted.
1. Set up area in both wild and captive areas for testing.
2. Choose the same marine mammal for both the wild and captive area to test.
3. Tag and assess health of the wild marine mammal. Asses the health of the captive mammal.
4. Monitor mammals for a year.
5. Record their behavior with detail and accuracy.
6. Asses health and behavior of both mammals after one year.
The animals in captivity appeared to be healthier and friendly to their tank mates. They were fed organic krill and were fed regularly, but were very nervous and slightly hostile to outside animals once they were exposed. The animals that were not in captivity fed on their own time but were not necessarily unhealthy. They were not hostile to other mammals and peacefully coexisted with other mammals in the ocean.
My results did not support my hypothesis. The mammals kept in captivity were healthier than the mammals in the wild, due to controlled setting, and regular nutritious diet. However their behavior was negatively impacted. They were nervous and somewhat hostile towards the wild mammals once exposed to the wild.
