Krill (an important food source for whales)
Sea birds
QUESTION 11
Which is NOT a problem when it comes to escaped farmed species?
The escapee might compete with natives species for mates
The escapee might compete with native species for food
The escapee might compete with native species for habitat
The escapee might compete with the native species for dissolved oxygen
QUESTION 12
What is the problem with some farmed fish being carnivores?
They require a wild source of food that must be caught by fishing
They will eat one another
They can chew through their enclosures
Carnivores are less desirable and have a lower market value
QUESTION 13
How are wild fish processed and used for something other than human food?
They are turned into base ingredients for make-up and other beauty products
They are processed into fishmeal and fish oil
Calcium from fish bones is extracted and used in the production of silicon chip wafers
Calcium from fish bones are used to in osteoporosis therapies
QUESTION 14
Aquaculture can be made more sustainable by:
raising free range and pen-free salmon.
using sustainable feed and raising fish that are not wholly dependent on wild food sources.
raising shrimp and salmon in the same system.
using genetically modified sources of feed.
QUESTION 15
Which seafood organisms might be a better choice for farming and why?
Mussels and oysters; because they are filter feeder that clean the water and do not need supplemental feeding
Bluefin tuna; because of their extraordinary growth rate and high reproductive rate
Salmon; because they can eat a wide variety of foods
Young eels; because they are small, taking up little space and have low nutritional requirements
QUESTION 16
Which of the following is NOT a way that longlining can be made safer for non-target species?
Adding streamers
Setting lines deeper
Using J-shaped hooks
Using circle hooks
QUESTION 17
Why is fish farming an issue for wild populations genetically?
Genetically weaker fish may escape and mix with wild populations
Wild fish may get into pens, breed with hatchery fish and take those poor genes to wild populations
Wild fish become dependent on genetically inferior feed that falls out of the submersible pens
Prey items for wild populations become genetically enhanced due to fewer predators
QUESTION 18
Which two aquaculture methods can be carried out inland (away from oceans or large bodies of water)?
Shellfish cultures and raceways
Ponds and recirculating systems
Suspended cultures and ponds
Open pens and raceways
QUESTION 19
Which two methods are most damaging to seafloor habitat?
Bottom trawls and dredges
Boat seines and pots
Boat seines and dredges
Pots and bottom trawls
QUESTION 20
Why are fish-aggregating devices (FADs) a problem?
FADs poison fish that swim near them
Whales may inhale them and suffocate
FADs are dangerous to sea turtles
FADs attract both target and non-target species
QUESTION 21
Give three seafood items that appear in each category in the Seafood Watch guide. What are the differences in how the items are classified? Explain why the same type of fish might fall into different categories?
