Fina;: Conservation

Question 1

threats to biodiversity

Answer 1

-Dams
- Extinction
-Habitat loss
-Invasive species
- climate change
- overfishing
-non-native species
-homogenization (less species turnover)
-illegal stocking

Question 2

habitat degradation

Answer 2

-in Western water
- dams, water diversions, and water withdraw create unnatural flows and block migration window for native fish
- introduced species
- homogenization

Question 3

flow modification

Answer 3

rivers is used like “pluming systems”, creates unnatural flows for migrating fish

Question 4

invasive species

Answer 4

• 77% illegally introduced in CO
  -reduces species turnover
  -no more diversity cause invasive dominate system

Don’t move invasive species (non-native plants, animals, pathogens)

Question 5

overfishing

Answer 5

• unregulated and unreported

Capture fisheries:
-illegal fishing
- destructive fishing (bottom trolling, dynamite fishing, cyanide poisoning, ghost nets)
- bycatch

Aquaculture:
- catching fish to feed fish
- water pollution
habitat destruction

Question 6

climate change

Answer 6

• reduce ecological footprint
• green energy
  -use of water

Question 7

destructive fishing

Answer 7

-bottom trolling
-dynamite fishing
-cyanide poisoning, ghost nets

• habitat destruction

Question 8

market values

Answer 8

-fished commercially and recreationally
-3 billion depend on aquatic derived protein
-200 million for jobs

Question 9

ecosystem values

Answer 9

-serve as apex predators and prey
- removing fish from ecosystem created effects on other species and habitats

Question 10

existence values

Answer 10

• value of knowing it exists

Question 11

bequest values

Answer 11

• wanting to protect species for future generations

Question 12

invasive species and prevention

Answer 12

invasive species: (non-native plants, animals, pathogens)

Anglers & Boaters:
-remove mud, plants, debris from gear/boat, plants from boat, drain water from boat, motor, trailer
-Dry, freeze or disinfect boots, boat and equipment to dry
- Never release unused bait

Everyone:
- Never transplant or release fish or other animals, or aquatic plants into wild

Question 13

illegal introductions

Answer 13

• 77% illegally introduced in CO
• bad for ecosystem

Question 14

sustainable seafood

Answer 14

Wild-caught: certified sustainable food, fish choice

Farmed: ASCU, BAP

BOYCOTT:
Aquaculture: Catching fish to FEED fish, water polution, habitat destruction

Capture Fisheries: Illegal fishing, destructive fishing, bycatch

Question 15

seafood pyramid

Answer 15

4 tiers
1 Top (eat less): Predatory fish (salmon, tuna)

2: Herbivores (carp, tilapia, catfish)

3: Forage fish (anchovies, sardines)

4 Bottom (eat more): Seaweed, Bivalves (Mussels, kelp, clams)

Question 16

carbon footprint

Answer 16

• reduce ecological footprint

Question 17

create awareness

Answer 17

• educate
• “you dont save what you dont love”
  -“ you cant love what you dont know”
