Fishing has been around for thousands of years. With advances in technology and population growth, commercial fishing now dominates the way we fish our ocean. Commercial fishing practices allow us to take large amounts of fish from our ocean, but these practices now threaten the health of our ocean. How we fish our ocean has important consequences to the overall health of the ecosystem. It is important to look at not only the volume of fish taken by commercial fishing, but also how we fish and what components of the ecosystem we are removing. Overfishing large numbers of top predators or large numbers of organisms at the base of the food web can impact all other organisms in that food web.
