AQUACULTURE
“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

• Oxygen 0-14 mg/L 21%
• Temperature + 10˚C + 40˚C
• Density Variable (4˚C) Constant
• Composition Variable* Constant
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?
CLASSIFICATION OF
AQUACULTURE
Extensive Aquaculture:
Minimal control, lower density, ponds,
third world
Intensive Aquaculture:
Highly controlled, high density,
RAS, raceways, confined
(industrialized)
 Egyptian tombs have bas-relief of fish (tilapia) being
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

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

  • 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 INTRODUCTION
  • 3. PROPERTIES OF WATER Aqueous Terrestrial • Oxygen 0-14 mg/L 21% • Temperature + 10˚C + 40˚C • Density Variable (4˚C) Constant • Composition Variable* Constant
  • 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)
  • 6.  Egyptian tombs have bas-relief of fish (tilapia) being 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 HISTORY OF AQUACULTURE

  • 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 Act of 2007 requires abidance of existing water quality laws and other pertinent laws
