Fishery activities play an important role in Malaysia's social and economic development.
The production of tuna from Malaysian waters has decreased due to widespread fishing
activities resulting in decreased and threatened tuna population. Excessive fishing takes
place as fisheries is a source of income for fishermen and fish is a source of protein in a
daily diet of humans. Furthermore, fishing activities are increased drastically due to the
development of sophisticated fishing gear. This will further encourage fishermen to
continue fishing activities with a lot of catches. Therefore, indirectly fish populations will
be affected and increasingly threatened. Logistics equation is used to model the
population growth of tuna. Overfishing model of the tuna populations is solved by
separation of variables. The result shows that two value of equilibrium point, which are
zero that referred to the extinction of tuna population. Another point is 1,000 that referred
to the sustainable value.
