What effect does cold water temperature have on a fish metabolism?
It slows it down.
What is used to grow plants in an aquaponics system?

Chlorine
What defense does a fish have against scratches and skin wounds?
Name 2 plants that would not be desired (grow poorly) in an aquaponics system.
Melons, Cactus, Cucumbers, Tomatoes, Peppers, Melons, Eggplant.
Koi
Plants that have more than the normal double set of chromosomes.
Polyploid
• Fish respiration
• Bacteria respiration
What is the most common cause of fish stress?
Overhandling
Water Quality
Overfeeding
Underfeeding
How do fish help the plants grow?
They produce waste which acts as nutrients for the water.
Largemouth Bass
What is the name of the plants in the greenhouse kept only to be propagated by herbaceous, soft stem cuttings?
Stock Plants
What is pH?
The degree of alkalinity or acidity of the water that arises from hydrogen ion or hydroxyl ion concentration.
Name 2 ways Aquaponics can potentially help the environment.
Less Water is Needed.
Chemical Fertilizers are not needed.
What are 3 considerations growers look at before producing a crop?
1. Marketability
2. Disease resistance
3. Profit potential
`
Tilapia
Highly technical method of asexual reproduction involving the culture or gorwing of small pieces of plant tissue.
Tissue Culture
Does pH in a tank fall or rise over time? Why do you think that is so?
Fall: Fish Food/Waste produces Ammonia which if not managed properly can lead to an acidic water problem.
Why do aquaculturists closely monitor the amount and type of feed that goes into an aquaponics system?
Because it can greatly impact water quality and fish health.
When choosing a media to use in an aquaponics system, what are 3 things we consider?
1. Availability
2. Cost
3. Quality
4. Type of hydroponic method used
Swordtail
Asexual method of reproduction in which the scion is fused with the rootsock.
Grafting
The fish produce waste called __________ which is converted by bacteria into ________ which is then converted into ___________- that can be used by the PLANTS.
Ammonia, Nitrites, Nitrates
What is the name of the fish pictured below? Does it live in cold water or warm water?
Plants that support their own weight are more desired by aquaponics growers. Name 2 plants that support their own weight and would be good in an aquaponics system.
• Leafy Veggies
• Herbs
• Strawberries
• Microgreens
Golden Shiner
A method of asexual reproduction whereby roots form on a stem while the stem is still attached to the parent plant.
Layering
SURPRISE: Grab 2 pH strips from Ms.Ligons. If your group can properly identify both tanks of the room correctly (acid/base/neutral) you get the points.
Copper Pipe/Copper in General
What are the names of the plants in the greenhouse and how do we water each one?
Poinsettias:watering cans, avoiding leaves.
Seedlings:Sub Irrigation
Ferns: Drip Irrigation
Aloe: Watering cans, waiting until dry before next water.
