What is sustainable fishing?
Anyone who has eaten a tuna fish sandwich can tell you that ocean is an important and delicious source of nourishment. 'Shellfish,' or marine invertebrates such as shrimp, crabs, lobsters, clams, oysters, and mussels, are delicious, healthy foods that are high in protein and low in fat. True fish such as tuna, cod, and salmon, are also high in protein. Many fish are excellent sources of healthy fats and oils which are necessary to keep our brains, hearts and circulatory systems functioning properly.
Fish and shellfish can continue to be an important and healthy food source for humans, but only if they are harvested properly. Unfortunately, many of the current ways that fish and shellfish are caught can be destructive to both marine habitats and the marine food chain. The following websites provides a good overview of different ways to catch fish and shellfish, as well as information about raising and farming fish, a process called aquaculture.
Why is sustainable fishing important?
Sustainable fishing is important and helps to maintain a healthy aquatic ecosystem. The term "sustainable fishing" defines fishing practices that do not harm the population of fish being caught or other species of animals living in the same area. Sustainable fishing practices protect the physical environment in which fish live.
