Look over all the information youâ??ve gathered, and generate a solution for the chosen sub-problem. You can brainstorm ideas, fine-tune them, and then narrow the list down as you compile the information youâ??ve put together by researching the problem, the criteria, and the constraints. Based on the data collected from your sources, propose at least two solutions to the chosen sub-problem. You should describe how this sub-problem will be solved, the rationale behind this solution, and how the prioritization helped determine this solution.

Defining the Problem and Sub-Problems
1. A description of your complex real-world problem, and an explanation about why
you chose this problem.
The complex real-world problem that I choose is overfishing across oceans. This is a problem
that has been raised. Research as well has it that fish reduces at an average rate of 3.5% every
year and the number has been increasing rapidly for the last two decades. This reason I choose
this problem is that fishing is my favorite activity. I always campaign for catching fish and
releasing them along with legal harvesting to ensure that healthy population is maintained.
2. A minimum of two sub-problems that are more manageable and solvable.
The two sub-problems are;
People are involved in the illegal harvesting of fish and illegal fishing activities.
Every year, there are no efforts made to ensure that fish are added to the oceans.
3. An explanation of how these sub-problems came about and are related to or a direct
result of the overall problem.
The first sub-problem comes about when people who are fishing or who have been given the
permit to fish, overfishes or rather catches or harvests more fish than the number which they
Hohmann 2
have been allocated by the government or the fish regulatory and conservatory body. Health fish
population on an annual basis is usually estimated or calculated by the use of the number of fish
in the contracts given to fishermen. However, if the fishermen become unfaithful and dishonest
to the point of breaching the contract and catching more fish than they are required to, then the
population will reduce over a period.
The low fish population is what causes the second sub-problem. Even though the various bodies
responsible for growing and increasing fish population in oceans do so, sue to the act of illegal
fishing and catching more fish than required, the fish population never grow since the problem is
exponential. This way, the mean population of the fish will always be at a constant lower value
or decrease exponentially
4. A description of how solutions to these problems connect with each other in solving
the overall problem.
Firstly, from the first sub-problem, if the illegal fishing business is curbed by ensuring that
illegal fishermen are stopped, then-then number of fish will not drop. This will in fact enable
more fish to reproduce and increase in number. Then, when this is done, introduce aquaculture
into the mix. Combination of aquaculture and the conducive environment for reproducing will
enable the fish to multiply and a healthy population will be realized within a very short period of
time. This way we will be able to maintain the population of fish to the optimal point, level or
number where it should be and an overall curbing and reduction of the real-world complex
problem of overfishing will be curbed.

5. A list of at least three sources you will use for research. These do not have to be in a
particular format.
The following are the resources used in the above brief research of my complex real-world

People are involved in the illegal harvesting of fish and illegal fishing activities.
Above is the sub problem selected. This problem is a lot easier to control as compared to
the other subproblem. In the other subproblem, there is very little that people can really do to
increase the number of fish in the sea or other large water bodies (Sustainable fishing, 2012). To
increase the number of fish in large water bodies, a lot of money and time would be required.
Extensive research would also be required. However, controlling illegal fishing can be easily
done by deploying marine patrol officers or even informing the people of the effect of excessive
fishing on both short and long run. For instance, excessive fishing could result to flooding of fish
in the market causing their prices to go down and in the long run the fish population would
decrease intensively. Few arrests could scare the offenders.
It is also important to note that fish industry plays very critical role in the economy of
many nations due to export and job creation. Food security is another significance of the fish
industry. Controlling overfishing has to be done carefully so that it will not affect people and
ecology in ways that were not expected. Increasing the population of fish in water bodies may
involve reducing the amount of harmful waste products into the water bodies. Small pod farming
could also serve to reduce overfishing in other water bodies ((n.d.). Retrieved from, n.d.).

Criteria for choosing the subproblem
After observations and report everywhere, it appears that it is easier to control overfishing
by influencing human behave. Human behavior can be geared towards a certain direction so that
a give objective can be met. Widely cited research shows that reducing overfishing that have
resulted to reduced number of fish in the oceans would involve massive human effort both from
the government and non-government bodies. All this is what people can be managed to do.
Efforts to increase the number of fish in the ocean is not guaranteed that would bring results
because of natural selection. So, the possibility of controlling overfishing and in reducing illegal
harvesting was the criteria used.
Technically, since reducing the overfishing is a step towards creating a sustainable
environment and preserving nature, human activities can be easily tamed. This will allow the
natural selection to control the fish population on the oceans. Fish that are harvested illegally
find their way in the black market where it is estimated that 11-26 million tons of the fish are
sold (Constraints and solutions for managing Pacific Island sea cucumber fisheries with an
ecosystem approach, 2013). This is about 20-30% of the total catch that are ma all over the
Considering the weight of human activity over the year that resulted to destruction of the
environment was the other criteria that was employed to select the subtopic. Human activities
such deforestation, farming near the river banks, industrialization and used petroleum fuel have
resulted to deuteriation of the environment. However, after research and massive mass education
on the their danger, people have changed and at least efforts are made to reduce their effects.
Thinking a long the same line, mass education and sensitization can help reduce the overfishing
and illegal harvesting of fish in the ocean.
Hohmann 3
Constrain on the selected subproblem.
The constrains that occurs when trying to solve overfishing and illegal harvesting of fish are;
Collecting data on the places where illegal harvesting and overfishing are carried
Harnessing the necessary resources in order to deal with the illegal harvesting and
The above limitations have for a long time hindered the speed with which the illegal
harvesting and overfishing would be prevented. Take for instance, collecting the data on the
places where illegal harvesting takes place would require looking for someone who is actually
involved in the illegal act. Such people could not be willing to give accurate information since
that would mean their only source of income would be done away with.
Harnessing the resource for controlling the illegal harvesting and overfishing would
actually take time since that may involve making policies that would be require implementation.
Furthermore, implementation would face resistance from members of the public since to some it
is the only source of income. Nonetheless, for future purpose and conservation of the
environment and the endangered species, policies have to be made very first.
Prioritization of criteria and constrains
In the end, human efforts are necessary to reduce the effect of the illegal harvesting of fish
and overfishing. Human are responsible for offset the natural selection in ways that have had
negative impact to both the environment and the people themselves. Mass education and
sensitization would be play a very good role (Sustainable fishing, 2012).
