Transformations in marine ecosystems produced by the functional elimination of apex predators, recently due to the increasing scale of human exploitation of the sea, can derive in complex and unpredictable consequences. As a consequence, it is expected a presumably increase of their prey populations, many of them secondary predators, with severe cascade down effects on the food webs (Baum et al. 2003, Myers et al. 2007, Dulvy et al. 2008). Hence, the management and conservation of wide-range predators

role of a keystone species in many environments, including human habitations, where they control some rodent populations. Feral cats are known to decimate native populations in many places in which they are introduced. These creatures need not be apex predators. Sea stars are prey for sharks, rays, and sea anemones. Cats and sea otters are prey for raptor birds. Engineers In North America, the grizzly bear is a keystone species - not as a predator but as ecosystem engineers. They transfer

Overfishing is a global issue that has many negative effects on the environment (Fisheries and Oceans Canada, 2009). Fish are a major resource that many people rely on for not only nutrition, but also for a means of income (Fisheries and Oceans Canada, 2009). As the population of the world increases, so does the demand for fish, which puts oceans under a lot of pressure (Fisheries and Oceans Canada, 2009). Due to advanced fishing technologies and equipment, going out further into the oceans and catching
