Longlining is a type of fishing in which a very long line-up to 100 kilometers (62 miles)-is set and dragged behind a boat. The net can scoop up many fish at a time, and is typically used to catch schooling fish or those that come together to spawn.
Purse seine fishing uses a net to herd fish together and then envelop them by pulling the net’s drawstring. Since about that time, commercial fishers have caught bluefin tuna using purse seining and longlining.
Today’s spawning population of bluefin tuna is estimated at 21 to 29 percent of its population in 1970. Demand for this particular fish has resulted in very high prices at markets and has threatened its population. It is known for its delicious meat, which is often enjoyed raw, as sushi. This fish is one of the largest and fastest on Earth. In order to continue relying on the ocean as an important food source, economists and conservationists say we will need to employ sustainable fishing practices.Ĭonsider the example of the bluefin tuna. Scientists fear that continuing to fish at this rate may soon result in a collapse of the world’s fisheries. Fishers remove more than 77 billion kilograms (170 billion pounds) of wildlife from the sea each year. For thousands of years, people have fished to feed families and local communities.ĭemand for seafood and advances in technology have led to fishing practices that are depleting fish and shellfish populations around the world. (Others are harvested for economic reasons, such as oysters that produce pearls used in jewelry.) Seafood is respected all over the world, in many diverse cultures, as an important source of protein and healthy fats. Aquatic environments are home to countless species of fish and invertebrates, most of which are consumed as food. Sustainable fishing guarantees there will be populations of ocean and freshwater wildlife for the future. This resource is also available in Spanish.
