So over time, the population of all organ- isms continued to grow at similar rates, and water never reached an equilibrium value. In reality, there has to be a natural limit, if for no other reason than that if the fish waste grows uncontrollably, it will eventually occupy all of the space, choking off nutrient access. One possibility would be to introduce an assumed limit to the ecosystem by confining the space to the Bolinao region. The water area of Bolinao covers 1170 ha. Based on the limit in the problem statement that the farmers currently use 50,000 milkfish to a pen and operate 10 pens per hectare, a natural limit is 585 million milkfish(500,000 milkfish/ ha x 1170 ha) Assuming this upper bound, we can base the growth rate from a factor of the difference between the current population of milkfish and the upper limit of 585,000,000, via the formula G(585000000-Pm) Despite the difficulty in achieving steady-state equilibrium of water quality, we still produce a model that demonstrates the general trend that should have been presentin the ecosystem before mass-farming of milkfish Task 2: Current Water Quality Poor water quality and the destruction of coral don' t really seem like problems to people who are trying to meet basic needs and keep their children healthy.
