Overfishing poses the greatest threats to the fish population in the Galapagos Islands. It is important that the fishing industry be as maintainable as possible. For fishing to be sustainable, fishermen should be able to catch enough fish to make a living from, but not to catch so many fish (commercial fishing) that the fish population is negatively affected. Catching too many fish is called overfishing. An example would be to fish for in demand endangered species which are in the protected area of the Galapagos Reserve. Without scientific research, it can be hard for fishermen to know if they are overfishing in an area.
