For some people, feeding a crowd is a holiday ritual, but at the Tennessee Aquarium, animal caretakers raid the pantry to feed the furry, scaly and feathered masses year-round.
From high-quality seafood and fresh produce to thousands upon thousands of insects, animal care specialists prepare species-specific meals tailored to meet the dietary needs of hundreds of species of fish, amphibians, reptiles, mammals and more.
With more than 12,000 animals in the Aquarium’s care, there are a lot of hungry mouths to feed.
Here are some noteworthy selections from the Aquarium’s food budget in 2024:
- 120 pounds of peas
- 3,072 ounces of frozen ocean plankton
- 2,304 ounces of bloodworms
- 15,000 mice
- 8,352 heads of romaine lettuce
- 900,000 crickets
- 1,500 pounds of scallops
- 60 pounds of blueberries
- 3,000 nightcrawlers
- 7,128 pounds of smelt
- 156,000 mealworms
- 198 pounds of zucchini
- 1,161 apples
- 2,217 oranges
- 12,566 pounds of capelin (a small cold-water fish)
- 260 pounds of fish pellets
- 665 pounds of carrots
- 1,692 pounds of krill
To help with the Aquarium’s food costs, last year, horticulturists began growing a selection of fruits and vegetables in-house, raising high-quality, organic produce to supplement the diets of animals such as Red-ruffed Lemurs, Desert Tortoises and Amazonian Pacu.
