What are some animals that are affected by overfishing?

Some of the species most threatened by overfishing currently include Atlantic Halibut, the Monkfish, all sharks, and Blue Fin Tuna. Other animals not usually associated with the seafood industry are also affected, with inadvertent by-catches claiming loggerhead turtles, sharks, dolphins and whales.

Who is most affected by overfishing?

Japan, China, the U.S., Indonesia, Chinese Taipei and South Korea have been named by Pew Charitable Trusts on a “shame list” of countries responsible for overfishing tuna in the Pacific. According to Pew, the “Pacific 6” are responsible for 80 percent — 111,482 metric tons in 2011 — of the annual catch of bigeye tuna.

Are dolphins affected by overfishing?

Dolphins, sharks and other large marine species around the world are going hungry as they seek out dwindling supplies of the small, overlooked species they feed on, according to a new study that says overfishing is draining their food sources.

What animals are overharvested?

Insects, oysters, octopus, crayfish, sea stars, scorpions, crabs, and sponges are all kinds of this animal class. Today many invertebrates—particularly marine invertebrates—are at risk from overharvesting.

How are coral reefs affected by overfishing?

Overfishing can deplete key reef species and damage coral habitat. ... Rapid human population growth, increased demand, use of more efficient fishery technologies, and inadequate management and enforcement have led to the depletion of key reef species and habitat damage in many locations.

How does overfishing affect other animals?

It can change the size of fish remaining, as well as how they reproduce and the speed at which they mature. When too many fish are taken out of the ocean it creates an imbalance that can erode the food web and lead to a loss of other important marine life, including vulnerable species like sea turtles and corals.

How are whales affected by overfishing?

Overfishing also threatens the whales. Scientists working with the International Whaling Commission estimate that 300,000 cetaceans (whales, dolphins and porpoises) die each year by entanglement in fishing gear. Ships strikes, pollution, ocean noise and climate change bring additional threats.

What marine mammals are affected by commercial fishing?

Our supporters helped us score a win in 2013 against California's remaining swordfish gillnet fishery, which has killed alarming numbers of sperm whales, leatherback and loggerhead sea turtles, bottleneck dolphins, California sea lions and many other species.

How many fish are killed as bycatch?

Often, it's not just the desired species that are caught but also many other undesired animals – so-called bycatch. In total, 38 million tonnes of sea creatures are unintentionally caught. That is 40% of fish catch worldwide.

What animals are affected by habitat destruction?

Orangutans, tigers, elephants, rhinos, and many other species are increasingly isolated and their sources of food and shelter are in decline. Human-wildlife conflict also increases because without sufficient natural habitat these species come into contact with humans and are often killed or captured.

What animals are affected by pollution?

Birds, fish, turtles, dolphins, sharks and even whales can be poisoned or trapped by plastic waste. And all animals (including humans) depend on the ocean for food and a healthy ecosystem that maintains the balance of greenhouse gases.

How does overfishing affect the hydrosphere?

The over fishing of sea creatures affects the rest of the Hydrosphere because the fish that are hinted are usually the top predators in the ocean. Making marine communities change and become unstable because of the smaller marine species becoming over-populated. This messes up the natural food chain.

How does overfishing affect us?

Overfishing endangers ocean ecosystems and the billions of people who rely on seafood as a key source of protein. Without sustainable management, our fisheries face collapse — and we face a food crisis.

How does overfishing affect the fish population?

Simply put, overfishing is when so many fish are caught that the population can't reproduce enough to replace them. Overfishing can lead to depletion of or extinction of fish populations. ... Deep sea fish are thought to be more at risk than shallow water fish due to their slow metabolism and smaller rates of reproduction.

How does overfishing affect land animals?

They found a 76% decrease in mammals, with many local extinctions. The fewer fish there were year to year, the harder the impact on land animals, they found. “If people aren't able to get their protein from fish, they'll turn elsewhere for food and economic survival.

How are sharks affected by overfishing?

Overfishing puts more than one-third of all sharks, rays, and chimaeras at risk of extinction. More than one-third of all sharks, rays, and chimaeras are now at risk of extinction because of overfishing, according to a new study re-assessing their IUCN Red List of Threatened Species extinction risk status.
