Chapter 4 Protecting Our Clean Water
Note: The laws affecting fish habitat
that are outlined on pp. 30 and 31 of Alaska’s Wild Salmon are
still in effect. In 2003 the responsibility for enforcing these laws and
for permitting activities in salmon bearing waters were moved from the
Alaska Department of Fish and Game to the Alaska Department of Natural
Resources in order to streamline the permitting process and provide for
additional clarity in interpreting the laws. Enforcement of these regulations
is now largely the responsibility of the Alaska Department of Natural
Resources in consultation with Department of Fish and Game staff.

Key Concepts
|
|
Individuals and communities make choices
that produce positive and negative impacts on salmon and their habitats.
It is important that Alaskans understand the consequences of their
actions on the health of watersheds and salmon resources.
The health and future of Alaska’s
wild salmon will depend, in part, upon our conservation efforts
and responsible development with regard to:
·
potential pollution & contaminants;
·
non-point source pollution;
·
invasive species;spread of Atlantic salmon in the
Pacific Ocean, and
·
fish farming.
|
|
Chapter Objectives
|
|
Students will be able to explain how choices
we make in land and water use can affect the survival of Alaska’s wild
salmon. They will understand effects of pollution and contamination, changes
in water volume or flow, invasive species, Atlantic salmon, and fish farming
on wild salmon.
Students will also understand:
·
steps they can take to help decrease negative impacts on
wild salmon, and
·
actions they can take to help protect and restore important
salmon habitat.
|
|
Terms Students Should Understand
|
|
pollution- the contamination of soil,
water, or air with noxious substances
non-point pollution- pollution from
non-specific sources. This includes accidental and incidental pollution
from our daily activities.
invasive species- living organisms
that thrive (and often compete with native species) when they are transported
either intentionally or by natural processes to places where they are
not normally found. In Alaska it is illegal to transport live fish without
a permit because of the dangers of introducing exotic species.
fish farming- the breeding, raising,
and harvest of fish in enclosures. This is different from ocean ranching,
which releases hatchery-bred fish to rear in the ocean and return.

Background for Teachers
|
|
See “Note” at the start of this chapter.
|
|
Do Alaskans need to worry about invasive
species?
|
Invasive species have been called the greatest
threat there is to America’s waters and watershed health. Although many
troublesome species are now well established in parts of the Lower 48,
few thus far appear to have become established in Alaska. Still, the problem
remains, and Alaskans must be alert to the potential hazards of exotic
organisms introduced through such sources as aquaculture, cargo shipped
on boats and planes, imported nursery and mail-order plants, and other
sources.
The Alaska Department of Fish and Game Division
of Wildlife Conservation web site describes invasive species threats in
Alaska and has developed an "Aquatic Nuisance Species Management
Plan," as well as the following suggestions that anglers can follow
to help prevent invasive species from entering as a result of sport fishing
activity:
·
clean all personal fishing gear and dry it thoroughly before
using it in Alaska,
·
wash lines and tackle in killing solutions of bleach or
water hotter than 150 degrees F.,
·
provide loaner tackle and gear to friends from Outside
to use while they are in Alaska.

Questions For Discussion
|
|
1. Refer to the quote from the Alaska
Constitution in the lefthand column on p. 30 of Alaska’s Wild Salmon.
Is it possible to “utilize, develop, and maintain” resources on the
sustained yield principle all at the same time? What are “beneficial uses”?
How can economic development and people’s need for jobs be reconciled
with the effects that resource extraction and community development activities
may have on waters that provide habitat for salmon?
What kinds of choices must communities make,
and how should “preferences among beneficial uses” be allocated?
What are some examples of local choices
that students consider successful or less successful?
|
There are no simple answers here. What is
important is that students realize difficult choices must be made, and
that we can all participate in processes for making community and statewide
decisions about resource management.
|
2. Students should be aware of the state
and several federal laws that work together to protect salmon habitat
and assure safe passage for Alaska’s fish. They will learn more about
the role of the agencies that enforce these laws in Chapter 7 (pp. 58-61).
|
A class discussion would help students think
about which laws they can see working in their community, and how the
laws interface with the needs of the community and the desires of individual
families and businesses.
|
3. Fish farming has been banned in Alaska.
Some people have proposed lifting that ban to allow Alaskans to raise
farm-reared fish. What are the arguments for and against this proposal?
|
Some arguments students might come up with
are:
Pro: Fish farming could provide
new jobs in the world market. Farms make fresh fish available year
around. Con: Farmed fish could introduce
pollution and invasive organisms, and would compete with wild salmon,
destroying genetic resilience just when environmental changes may
require it more than ever. Many commercial fishermen feel fish farming
would destroy the small operator salmon fisheries prevalent in Alaska.
|
4. Have students study the pie chart on
p. 32 of Alaska’s Wild Salmon, then discuss potential sources of
the various types of pollution in their community, particularly as they
could affect salmon and their habitat at various stages of the life cycle.
What is being done to curtail or control them? How effective is it? What
could students do to help?
|
|
5. What can all Alaskans do to help prevent
the introduction or expansion of invasive plants and animals in their
communities?
|
See Alaska Dept. of Fish and Game plan for
dealing with invasive species. (See Resources later in this chapter.)
|
6. Refer to the top photo on p. 34 of Alaska’s
Wild Salmon. Why would people introduce a species such as northern
pike into waters in which they don’t occur naturally? How can we educate
people about the dangers of such introductions?
|
|
Ideas for Activities
|
|
1. Have students list for one day all the
times they use clean water, and in what approximate quantities. Then have
them investigate: Where does their water come from, and could their usage
have any potential impact on salmon habitat? What would happen if their
family and community population grew substantially? What precautions could
be taken to meet community needs but also protect salmon?
|
Invite students to produce written material
or a display to share what they have learned with members of the community.
|
2. Assign groups of students to look for
potential sources of non-point source pollution that could affect salmon
habitat in their homes and in various sites in the community. The idea
is not to point fingers but to identify problems, see what is being done,
and see if efforts to control pollution could be improved. Then, using
the list on p. 33 under “What You Can Do,” have them propose three things
they could do to help minimize pollution effects on salmon and their habitat.
|
Here are just a few examples: Besides looking
around their homes for fertilizers, pesticides, etc. and how they are
used and disposed of, students might:
·
go to a parking lot and look for oil slicks – Where do
they go when it rains? Are they adequately controlled?
·
visit the boat harbor – Are there provisions for pumping
sewage tanks, disposing of waste oil, and cleaning up bilge water? How
are people encouraged to use amenities that may be provided?
·
check out ATV trails – Do they cross salmon streams? Could
anything be done to educate riders and/or reroute trails?
|
3. Have students visit the Alaska
Department of Fish and Game invasive species web site to learn more
about Survey local agency personnel for information on possible
invasive plants and animals in their area and in Alaska.
What fish species in their region have come from other places? Have
they had beneficial or harmful effects? What can the class do to
help monitor or control these and other potential invaders? Ask
them to share their information and ideas with the community.
|
Students might also survey local agency
personnel, talk with their parents or elders about changes in local plants
and animal species, or look at possible sources of invasive species in
their community. Research on the internet can help them understand the
problems other states and countries are facing from invasive species.
|
4. Have students role play questions and
decisions that would emerge if a new business were proposed that would
affect salmon habitat, especially water quality, volume, or flow, in the
community. Assign students or groups to research and represent the interests
and perspectives that would be represented by such players as the business
owners, adjacent property owners, people and groups who harvest fish,
regulatory agencies, and others. Hold a mock hearing or town meeting in
which students present their viewpoints.
|
An “audience” of students, invited
parents, or invited agency personnel could comment on how convincing
student representatives were, what other issues might be relevant,
and what they think the community decision might be as a result
of the mock hearing.
|
5. Societies usually protect the things
they value the most. Ask students to think about how their community values
clean water for human use, and to explore how clean fresh water is valued
around the globe. Can they imagine any scenario in which people would
be competing with salmon for a certain volume and flow of clean water
in your community? (What if the community started a water bottling plant?
What would be valued more, salmon or water? How would salmon habitats
be affected?) Discuss how much we value clean water, and how people in
other parts of the U.S. and the world value water. Some students may research
concerns about global water shortages.
|
An interesting exercise is to have students
visit local stores to determine the amount of shelf space devoted to bottled
water and its price per gallon. Have the class compare the price per gallon
of water and gasoline or diesel fuel.What is the economic value? In what
other ways do we establish values for resources? How can values change
over time? And how might salmon be affected by changing values?
|
6. Have students discuss the information
on p. 35 about Atlantic salmon. Be sure they could identify and know where
and how to report a catch of Atlantic salmon.

Invasive species
|
This web site describes the history and
threat of invasive species in Alaska and the Alaska Department of Fish
and Game “Alaska Aquatic Nuisance Species Management Plan” to monitor
and control them. The first 14 pages are an excellent overview of the
history and threats of invasive species, and there is a link to the department’s
white paper on Atlantic salmon.
|
Farmed and Dangerous
|
This web site of the Coastal Alliance for
Aquaculture Reform discusses problems of farmed salmon as exotic species.
|
Many of the references used in Chapter 3
regarding salmon habitat and watersheds can be revisited from the perspective
of the need for volume and flow of clean water.
