What does MoLaRS stand for?
Modular Larval Rearing System
What type of algae do parvo copepods eat?

What is it called when you feed a fish to they are full? How do you know the animal is full?
Satiation. You know the animal is full when they no longer show interest in the food and the food falls to the ground of the tank.
If you look into a larval tank and see the larve walling what do you do?
Add algae to the tank
What is the ideal stocking density of a new copepod tank?
2 adults/ mL
When doing water quality, what levels of ammonia, nitrite, and nitrate should cause you to do conduct a water change in a shrimp system?
Ammonia: Above 0
Nitrite: Above 0
Nitrate: 20 and above
What 3 species of fish work are part of our partnership for NEAQ?
Lookdowns, Sweepers, and Grunts
How long does it take for a carboy to come up to proper density
14 days
How can you tell if larvae are eating artemia?
Either you can see orange guts or you visually watch the larvae strike and eat the artemia
what type of algae do we feed to the sea urchins
amphoria
When shrimp are in bad water quality, what body part is effected and what happens?
The antenna is affected. The antenna turns wavey or curly.
How much do Yasha gobies sell for?
10 dollars
Name a type of mechanical and biological filtration found in the lab
Mechanical: filter sock
Biological: media balls
Name the order in which live feeds are fed out.
Demonstrate through dance how adult copepods, rotifers, and artemia move in the water column.
Adult copepods: Darting motion
Rotifers: Gliding motion
Artemia: Fluttering motion
What color are fire shrimp eggs?
Bright orange
What varieties of clownfish fall under the Amphiprion ocellaris species (5)
Common, Darwin, Mocha Vinci, Wyoming, Misbar
What does a protein skimmer do?
Removes organics from the water through foam fractionation
What species of algae can we not use for larval? Why?
TW, Rhodo, and Chaeto. We can not use because diatom and the organisms are abrasive to the larval fish
Because independently they will not provide proper nutrition to the fish.
What factors effect shrimp reproduction (4 answers, must get all four)
Temperature, diet, environment, age
Name the clownfish pairs in 20-B-6 and 20-C-3
Darwin, Common Clown, Picasso
