Questions and Answers

What is the primary difference between aquaculture production and fisheries production?

Aquaculture production involves individual/cooperative ownership of stock, while fisheries production involves variable recruitment and unpredictable stock size.

Aquaculture production implies individual/cooperative ownership of stock, while fisheries production implies heavily overexploited stock.

Aquaculture production involves enhancing captive stock, while fisheries production involves hunting-gathering activity.

What distinguishes fish culture from aquaculture?

Fish culture implies public ownership of stock, while aquaculture involves enhancing captive stock.

Fish culture involves farming aquatic animals, while aquaculture involves farming aquatic organisms (plants or animals). (correct)

Fish culture implies individual/cooperative ownership of stock, while aquaculture implies variable recruitment and unpredictable stock size.

Study Notes

Aquaculture vs. Fisheries

Aquaculture is the farming of aquatic organisms, while fisheries involve harvesting wild populations.

Fish Culture vs. Aquaculture

Fish culture focuses specifically on raising fish, while aquaculture includes the farming of all aquatic organisms, including mollusks, crustaceans, and seaweed.

Seafood

Seafood is any edible marine organism.

Capture Fisheries

Capture fisheries involve the harvesting of wild fish and other marine organisms from natural environments.

1990s Productivity

Capture fisheries experienced a mean yearly productivity increase of less than 1% during the 1990s.

Aquaculture in China

Aquaculture first developed in China around 2,000 years ago.

American Fisheries Society Predecessor

The American Fish Cultural Association, founded in 1870, is the predecessor of the American Fisheries Society.

Oyster Farming in Ancient Times

Oyster farming began around 2,000 BC in China.

Dominant Aquaculture Species

Carps dominate world aquaculture production.

Non-Mollusk

Crabs are not mollusks.

Distinction of Aquaculture Production

Aquaculture involves the controlled cultivation of aquatic organisms, while fisheries rely on harvesting wild populations.

Fish Culture vs. Aquaculture Distinction

Fish culture specifically focuses on raising fish, while aquaculture encompasses the farming of all types of aquatic organisms.

Capture Fisheries Characteristics

Capture fisheries harvest wild fish and marine organisms from their natural environments.

Shellfish Characteristics

Shellfish are marine invertebrates with a hard outer shell, including mollusks and crustaceans.

Seafood vs. Fish Culture

Seafood refers to edible marine organisms, including fish, while fish culture involves the farming of fish specifically.

Late Development of Aquaculture

The late development of aquaculture, compared to terrestrial agriculture, is attributed to the complex and unique challenges of aquatic environments.

US Fish and Wildlife Service Predecessor

The U.S. Commission of Fish and Fisheries, established by the U.S. Congress in 1871, is the predecessor to the U.S. Fish and Wildlife Service.

Early Fish Culture in China

Carp species, particularly the Grass Carp, might have been the earliest fish to be cultured in China.

Controversial Success

The introduction of the Nile perch into Lake Victoria, which led to the extinction of over 200 native fish species, is a controversial success story in aquaculture.

Dominant Aquaculture Group

Carps dominate world aquaculture production.
