What is Aquaculture?
Rick Sokol
1. List the five different purposes of aquaculture cultivation and an example of each.
Food – raising rainbow trout
Stocking – supply fingerlings (baby trout) to other producers
Bait – raising minnows
Ornamental – Japanese Koi
Industrial – cultured fresh water pearls
2. Explain one of the major forces pushing the growth of aquaculture.
Desire for year-round supplies
Specific quality
Specific appearance
Wild harvest could not have supplied enough fish to support existing demand
3. List five species of aquatic plants and animals farmed in the U.S. aquaculture
industry. In addition, also list whether the species is grown in fresh water or marine.
Channel fish, fresh
Salmon, both
Trout, fresh
Bait, both
Ornamental fish, both
Crawfish, fresh
Shrimp, marine
Oysters, both
Clams, marine
4. Compare and contrast the feed conversion of fish to other common commercial
livestock.
Fish convert feed into flesh about two times more efficiently than chickens and five
to ten times more efficiently than beef cattle
Fish can use foods that are less usable by most land animals
Fish require less energy from their foods.
Fish can use the entire pond, top to bottom, for living space, while land animals are
confined to the ground.
