Question

why do scientists think its unlikely that mariculture will allow a significant reducution in over fishing of wild stocks in foreseeable future?

Answer 1

Answer:

Sustainable fishing guarantees there will be populations of ocean and freshwater wildlife for the future. Aquatic environments are home to countless species of fish and invertebrates, most of which are consumed as food. (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. For thousands of years, people have fished to feed families and local communities.

Demand for seafood and advances in technology have led to fishing practices that are depleting fish and shellfish populations around the world. Fishers remove more than 77 billion kilograms (170 billion pounds) of wildlife from the sea each year. Scientists fear that continuing to fish at this rate may soon result in a collapse of the world’s fisheries. 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.

Answer 2

Answer:

Fishing may disrupt food webs by targeting specific, in-demand species. ... It may also cause the increase of prey species when the target fishes are predator species, such as salmon and tuna. Overfishing and pollution of the oceans also affect their carbon storage ability and thus contribute to the climate crisis.
