Intro
These are the two main types of water used in aquaculture: freshwater and this.
What is saltwater?
Natural or induced spawning can occur here.
What is hatchery?
This practice involves raising one species in an aquaculture system, often for efficiency and control.
What is single species?
This type of aquaculture is done in ponds, tanks, or raceways on land rather than in the ocean.
What is land-based aquaculture?
This is similar to rack and bag except oysters are placed in these and can be stacked on the sea floor to maximize space.
What is tray culture?
This is known as raising aquatic organisms in controlled environments.
What is Aquaculture?
A large facility where fish are transfered, fed, and cared for to grow to market size.
What is grow out operations?
Growing plants + fish farming
What is aquaponics?
These man-made water bodies are commonly used to raise freshwater fish.
What are ponds?
These confine aquatic life in larger bodies of water protecting the fish from predation and allowing for better control over the diet and water quality surrounding the fish.
What are cage/net pens.
industry focused on catching aquatic organisms from the wild.
What are fisheries?
A place where juvenile fish are raised before being transferred to a fish farm or a larger facility to grow-out.
In this system, fish waste can be used by seaweed and shellfish to improve water quality.
What is integrated multitrophic aquaculture (IMTA)?
This type of aquaculture system recycles water through filtration and biological treatment to reduce water use.
What is a recirculating aquaculture system (RAS)?
This system is commonly used in shallow coastal areas where oysters are grown in cages, bags, or racks on the seafloor.
What is bottom culture?
The area where fertilized eggs are held under optimal conditions for growth and maturation.
What is hatchery?
Aquatic organisms are officially removed from system for market or consumption.
What is harvest?
This sustainable system relies on a symbiotic relationship between fish, bacteria, and plants to recycle nutrients.
What is aquaponics?
This system produces minimal waste water and retains 95% of the water used daily.
What are RAS?
These are farmed on long floating lines. These must be farmed at the surface so that they have access to sunlight to photosynthesize.
What is seaweed aquaculture?
Fish are often raised in ponds, tanks, or these floating ocean enclosures.
What are cages (or net pens)?
Increasing this factor can increase production but may lead to poor water quality and increase chances of disease if unmanaged.
What is stocking density?
This farming approach reduces pollution by turning uneaten feed and waste into resources for other organisms.
What is integrated multitrophic aquaculture?
These nets are used to gather the fish to one side of the pond for harvest.
What are Seine nets
This has the added benefit of keeping the shellfish out of reach for most predators. An example can be mesh bags filled with shellfish and maintained with floatation or lines attached to posts or shellfish placed in “socks” (long narrow bags).
What is top culture?
