Fish that are able to regulate their salinity in both fresh and salt water.
Stenohaline
Euryhaline
Osmoconformer
Osmoregulator
One community where fish may do some anaerobic respiration is
The Epipelagic Zone
Coral Reefs
Kelp Forests
Hydrothermal Vents
Which of the following adaptations would be beneficial to fish in low oxygen environments, such as Mangrove Forests?
A smaller gill surface area with few large filaments
A smaller gill surface area with many small filaments
A larger gill surface area with few large filaments
A larger gill surface area with many small filaments
Which of the following best identifies the problems, for Salmon, associated with laying eggs in nest covered with leaves and rocks.
Stacking eggs decreases the surface area to volume ratio and therefore slows down oxygen uptake and development.
Stacking eggs increases the surface area to volume ration and therefore slows down oxygen uptake and development
Stacking eggs and covering them in leaves creates the potential for predators to see the eggs and eat them
Stacking eggs has no affect on the diffusion rate of gas exchange.
Which two organisms are most likely to lose many offspring to predation?
Tuna
Clownfish
Grouper
Salmon
Newly hatch Salmon are known as
Fry
Alevin
Parr
Smoult
If you were a Salmon fisherman/woman and no restrictions existed in the fishing industry, where and when would you fish for Salmon?
Late Summer/open ocean
Early Spring/estuary
Late Winter/Estuary
Early Fall/open ocean
Identify this phase
Alevin
Fry
Parr
Smoult
[3] Describe the mechanism for Tuna ventilation.
Fish swims with mouth open at a high speed
Water flushes over the gills and oxygenates the blood
Water is contantly forced over the gills
This is passive and requires, no muscle contraction
As the mouth closes, water is forced over the gills.
[2] Suggest why the use of milk could be hazardous.
It leeches vital nutrients away from the mother.
Making it taps into the mother's reserved carbohydrate energy.
It can be toxic at too high of a consumption level.
It exposes the mother to predation.
Bulking up increases the size of the whale, thereby decreasing the surface area to volume ratio causing hypoxia.
