Aquaculture is the farming of fish, shellfish, and aquatic plants. It involves cultivating these organisms under controlled conditions and can be contrasted with commercial fishing which harvests wild populations. Aquaculture is the fastest growing food production system and almost half of the seafood consumed worldwide now comes from aquaculture farms. While aquaculture has grown quickly over the past 30 years, the practice of fish farming dates back thousands of years to ancient Egypt and China.

2. “Seafood is one of the healthiest and most popular
sources of protein worldwide. Almost half of the
seafood we eat comes from farms, making
aquaculture - seafood farming - the fastest growing
food production system in the world…Despite a
steep learning curve for this growing industry –
learning in just 30 years what land farmers have
garnered over 6,000 years – positive changes in the
industry already are visible.” –worldwildlife.org

4. Aquaculture, is also known
as aquafarming. This is the farming
of fish, crustaceans, molluscs, aquati
c plants, algae and other aquatic
organisms. Aquaculture involves
cultivating freshwater and saltwater
populations under controlled
conditions, and can be contrasted
with commercial fishing, which is
the harvesting of wild fish
WHAT IS AQUACULTURE?

5. CLASSIFICATION OF
AQUACULTURE
Extensive Aquaculture:
Minimal control, lower density, ponds,
third world
Intensive Aquaculture:
Highly controlled, high density,
RAS, raceways, confined
(industrialized)

removed from ponds – 2500 B.C.
 Carp were farmed in China as early as 2500 B.C.
 Wen Fang – founder of the Chou Dynasty is called the
first fish farmer (during exile he kept records of fish
growth and behavior)
 Fan Li – wrote first book on fish farming 475 B.C.
 Lee family – Were the first to polyculture carp during
the Tang
Dynasty 600 to 900 A.D.
 England – 1500 A.D. carp culture was introduced
U.S. – first fish hatchery was in Oregon 1877

10. HOW CAN AQUACULTURE
HELP?
Gives people more control of
conditions
Restores depleted species of
fish & shellfish
Boosts commercial catches
and sports fishing
Complements wild catches to
meet growing demand
Improvements of fishmeal
Nat’l Offshore Aquaculture
