The controlled of aquatic organism
The majority of the shrimp production comes from
China
The aquaculture production includes
- Freshwater species
- Seawater species
- Brackish water
- Invertebrate species
- Plant species
What percentage of global seafood consumption comes from aquaculture
32%
T/F Most of the seafood production from aquaculture is produced in U.S
False. It comes from China
Primary product of China is
Shrimp and Carp
What does Asia specialized in the aquaculture production
Shrimp, marine fish and oysters
Primary product in Chile
Salmon
Primary production in U.S
Catfish
Primary production of aquaculture in Florida
Tropical fish
What are the two types of aquaculture products
Food animals and Non-food products
Give three examples of food animals
Fish
Shellfish
Shrimp
Give three examples of non-food products
Leather goods
Aquatic fish
Research animals
What are the types of systems used in Aquaculture production
- Earthen ponds
- Raceways
- Cages and net pens
- Re-circulating tank system
- Underwater lease
List 2 advantages and disadvantages of earthen ponds
Advantages:
- The water is free or “cheap”
- There is no need to circulate water
Disadvantages:
- Minimal control of the environment
- High risks of predation
List two advantages and disadvantages of Raceway production
Advantages:
- Uses free water from river or other source
- Use flow to maintain water quality
Disadvantages:
- Poor control of water source
- Effluent concerns
List two advantages and disadvantages of the cage system
Advantages:
- Easy to harvest
- Tidal flush provides free water exchange
Disadvantages:
- Susceptible of storm damage
- Exposure to predation
List two advantages and disadvantages of Re-circulating system
Advantages:
- Elimination of predation
- Complete control of the environment
Disadvantages:
- Requires expensive investment and management
- Loss of water kills all the species within minutes
List two advantages and disadvanatges of underwater lease
Advantages:
- Free water
- Free feed
Disadvantage:
- Storm damage
- Changes in salinity
The state of Alabama produces
Catfish
List 3 potential solutions for aquaculture to grow
- Establish an Economic Aquaculture Development
Potential solutions for aquaculture to grow
- National Economic Aquaculture Development that does not just focus on research but target aquaculture as an economic tool
- Eduacation (better education) to understand the culture
- Pemetting process need to be shortern
The state of Washington produces
Salmon
The state of Maine produces
Oysters
T/F Aquaculture has the most environmental impact
False
Explain why do fish have a higher source of protein and are able to grow better than terrestrial animals
Fish are able to put almost all their energy into growth because they don’t have to fight gravity or thermoregulate like all terrestrial animals do.
List 3 advantages of Aquaculture
- If done correctly, aquaculture have one of the lowest environmental impacts
- Having farm productions inside the U.S increases job and adds to the economy
- Producing fish inside the U.S decreases the need to rely on other countries
What percentage of the seafood that you eat is likely to have been farm-raised?
About 7%
Which specie is reared in Cages
Salmon
Which specie is reared in re-circulating tank systems
Tilapia
Which species is reared underwater lease
Shellfish and clams
What species are reared in ponds
Catfish and Shrimp
What species are reared in raceways
rainbow trout and ornamental fish
What are some major concerns about further development of aquaculture in the US?
The main concern about further development of aquaculture is environmental harm.
What are some of the challenges in aquaculture
- Not every state in the U.S has a coordinated permanent system
- A lot of things being done in aquaculture are relative new
