What is Commercial Fishing?
Commercial fishing is the activity of catching fish and other seafood for commercial profit, mostly from wild fisheries

What is Fish Farming?
Fish farming or pisciculture involves commercial breeding of fish, usually for food, in fish tanks or artificial enclosures such as fish ponds.

A. commercial vessels only (ferries, cruise ships, whale watching vessels...)
B. recreational vessels only (people's own boats)
C. shipping vessels only (freighters, tankers, cargo ships...)

What are negative and positive impacts of logging?
Negative: Loss of habitat for animals, loss of biodiveristy, degrading ecosystems, less absorption of carbon, increased temperature, errosion, floodings.
Positive: Wood to heat our homes, to build stuff.

What is "bycatch" and how does it impact our oceans?
Bycatch is when other species of fish or marine mammals are caught in the nets or equipments when fishing for a specific species.
It has a negative impact on our oceans by injuring and/or killing fish and marine mammals. - Population decrease.
300
What resource management method allowed the whale population to rebound?
A hunting ban placed in 1966!
300
What are some reasons that we use Fish Farms? Provide at least 2 reasons.
1) To raise the fish to maturity and release into the wild.
2) To provide fish for the growing population.
3) To reverse the overfishing of the wild population
Other answers may be accepted at the Eagle Wing Teams discretion.
300
Name one reason why it is important to minimize the impact that vessels have in the Salish Sea
Is it: the Salish Sea is home to an endangered population of killer whales (the southern resident killer whales), the Salish Sea is home to a variety of different wildlife that depend on the sea for survival (bald eagles, bears, sea wolves...), boat strikes represent a serious threat to whales (especially humpbacks) and other wildlife

Name three natural resources we can use for energy
Sun, Wind, Water, Nuclear, Fossil fuels, Geothermal

Name 3 ways commercial fishing contributes to pollution.
Air pollution - burning fuel
Water pollution - fuel, fishing equipment left in the water, plastic
Noise pollution - vessel noise, underwater noise
400
The Salish Sea had 1 Humpback in 1997 and around 50 Humpbacks in 2011. How many Humpbacks do we have in 2023?
A) 60
B) 100
C) 200
D) 400
E) 850+
We now have over 850 humpbacks every year in the Salish Sea!

What are the impacts on the surrounding environment due to fish farms? Multiple answers accepted.
1) Pollution from fish waste in a tight concentrated area.
2) Veterinary medications
3) Oxygen depletion due to waste
4) Toxic algae blooms
400
Name one policy set in place to manage the vessel traffic transiting through the Salish Sea to minimize the impact that vessels have on wildlife
Is it: slowing down in the presence of whales; minimum distance to which one can approach; protected areas like Race Rocks Ecological Reserve?
500
What are fossil fuels made from?
Dead plant and animal material burried, compacted and changed over many millions of years.
500
What is the most valuable tree for logging on Vancouver Island?
A) Arbutus Tree
B) Cedar Tree
C) Gary Oak
C!
One of the most valuable trees to the West Coast, Garry Oaks have been used for thousands of years for materials and food, but are now part of the most endangered Canadian ecosystems. They provide an incredibly rich habitat for wildlife, and these special trees are worth planting and preserving for future generations.
500
Name 1 regulation that can ensure our fisheries don't get overfished.
1. Maximum number of fish per day (having a sustainable quota)
2. Needing a fishing license
3. Fishing seasons - that differ for the species and depends on their life cycle
500
Why is it so important that the Humpbacks have made a comeback?
A) Humpback Whales are Cool
B) More food for our orcas
C) They produce more food than they eat
D) Keeps the fish population controlled
C! Humpback whales produce more food than they eat by kicking their flukes. This causes nutrient upwelling which is normally done by the tides!
500
How are the fish negatively impacted by fish farms?
1) Lack of natural selection (poor genetics)
2) Farmed fish escape and breed with wild stocks potentially passing on the poor genetics and spread diseases.
3) Sea lice attach to these fish due to lack of space to move and can be passed on to other fish species.
