Problem A: Moving North
Global ocean temperatures affect the quality of habitats for certain ocean-dwelling species.
When temperature changes are too great for their continued thriving, these species move to seek
other habitats better suited to their present and future living and reproductive success. One
example of this is seen in the lobster population of Maine, USA that is slowly migrating north to
Canada where the lower ocean temperatures provide a more suitable habitat. This geographic
population shift can significantly disrupt the livelihood of companies who depend on the stability
of ocean-dwelling species.
Your team has been hired as consultants by a Scottish North Atlantic fishery management
consortium. The consortium wants to gain a better understanding of issues related to the potential
migration of Scottish herring and mackerel from their current habitats near Scotland if and when
global oceantemperatures increase. These two fish species representa significanteconomic
contribution to the Scottish fishing industry. Changes in population locations of herring and
mackerel could m吐e it economically impractical for smaller Scotland-based fishing companies,
who use fishing vessels without on-board refrigeration, to harvest and deliver fresh fish to
markets in Scotland fishing ports.
Requirements
1. Build a mathematical model to identify the most likely locations for these two fish species
over the next 50 years, assuming that water temperatures are going to change enough to cause
the populations to move.
2. Based upon how rapidly the ocean water temperature change occurs, use your model to predict
best case, worst case, and most likely elapsed time(s) until these populations will be too far away
for small fishing companies to harvest if the small fishing companies continue to operate out of
their current locations.
3. In light of your predictive analysis, should these small fishing companies m吐e changes to
their operations?
a. If yes, use your model to identify and assess practical and economically attractive
strategies for small fishing companies. Your strategies should consider, but not be limited
to, realistic options that include:
- Relocating some or all of a fishing company's assets from a current location in a
Scottish port to closer to where both fish populations are moving;
- Using some proportion of small fishing vessels capable of operating without landbased
support for a period of time while still ensuring the freshness and high quality
of the catch.
- Other options that your team may identify and model.
b. If your team rejects the need for any changes, justify reasons for your rejection based
on your modeling results as they relate to the assumptions your team has made.

Sinker
4. Use your model to address how your proposal is affected if some proportion of the fishery
moves into the territorial waters (sea) of another country.
5. In addition to your technical report, prepare a one- to two-page article for
magazine to help fishermen understand the seriousness of the problem and how your
proposed solution(s) will improve their future business prospects.
Your submission should consist of:
• One-page Summary Sheet
• Table of Contents
• One- to Two-page Article
• Your solution of no more than 20 pages, for a maximum of 24 pages with your summary,
table of contents, and article.
凶堂Reference List and any appendices do not count toward the page limit and should appear
after your completed solution. You should not make use of unauthorized images and materials
whose use is restricted by copyright laws. Ensure you cite the sources for your ideas and the
materials used in your report.
Glossary
Fishery: The collection of fish of a given species and the area that they inhabit.
Habitat: The type of environment in which an organism or group normally lives or occurs.
Small Fishing Company: A company engaged in commercial fishing with limited or very
limited financial resources to invest in new equipment/vessels.
Territorial Waters (sea): "as defined by the 1982 United Nations Convention on the Law of the
Sea, is a belt of coastal waters extending at most 12 nautical miles (22.2 km; 13.8 mi) from the
baseline (usually the mean low-water mark) of a coastal state. The territorial sea is regarded as
the sovereign territory of the state, although foreign ships (military and civilian) are allowed
innocent passage through it, or transit passage for straits; this sovereignty also extends to the
airspace over and seabed below." [Territorial Waters. (n.d.). In Wikipedia. Retrieved January 28,
2020, from https://en. wikipedia.org/wiki/Territorial waters.]
