Spatial Fishery Model

Abstract

In the previous chapter we saw that, to a significant degree, fish population dynamics may be attributed to economic factors. This is not surprising, as humans are frequently the number one predator of fish species. Consequently, fisheries models must very carefully incorporate economic adjustment processes. In this chapter we show that differences between the model result and actual system behavior are also significantly dependent on the spatial resolution of the predator—prey models in use.

Then I say the earth belongs to each . . . generation during its course, fully and in its own right. . . . Then, no generation can contract debts greater than may be paid during the course of its own existence.
