Geographical Information Systems (GIS) as a Simple Tool to Aid Modeling of Particulate Waste Distribution at Marine Fish Cage Sites
From the amount of farmed raised fish that flow in and out of grocery stores and restaurants, there must be one that causes food poisoning? Well this could be due to high levels of organic matter within the large pools that the fish come from. In this article, carbon settling at the bottom of the large tanks in the form of uneaten food and fecal matter is brought to the forefront of the conversation through using GIS technology.
This interesting article from O. M. Perez, brings in old formulas that help calculate carbon distribution within and around the tanks. Perez uses these formulas to calculate the numbers that are then applied with GIS to come up with some highly informative graphs and diagrams.


These two graphs show the distribution of carbon within one tank on the property of a fishery. These graphs help fishery owners begin to realize why some of their fish are losing them money and then harm the buyer with possibly contaminated fish.

By using the formulas that are presented in the article these graphs are formed and help environmentalists to change the ways of filtering and help them begin to theorize about new ways to grow the farm raised fishery business. At the end of this article however Perez brings us back to reality and tells us how this technology is still not sufficient enough to change the world with just a few examples. This lack of using technology especially GIS technology is holding new ways of production back and should be changed just how Perez is emphasizing.

  1. This is an interesting article, I've never thought about fish giving the consumers food poisoning due to an accumulation of carbon at the bottom of their tanks. It's also interesting that GIS can be applied in this way. I never thought it would be used like this. I wonder if they have found a solution to this problem by now..
