Every year, hundreds of thousands of whales and dolphins around the world are accidentally killed in fishing nets and ropes. This is the biggest cause of harm to whales, dolphins and porpoises in the ocean. Whale and dolphin bycatch is estimated to cost the global economy more than $100 billion a year.
It is also a major threat to the health and welfare of the animals, as well as the livelihoods of fishermen, trawlers and marine park operators. Bycatch can be caused by a wide range of factors, including fishing gear, nets, fishing vessels and fishing equipment, and by-catch of other species, such as seabirds, sea turtles and sea lions.

How many dolphins are killed due to overfishing?
The report, published in the journal Proceedings of the National Academy of Sciences (PNAS), found that the global population of marine mammals has declined by more than a third since the 1970s, with the number of whales, dolphins, sea turtles and seabirds falling by almost a quarter.
The decline in marine mammal populations has been driven by a combination of factors, including pollution, climate change, over-exploitation for food and habitat by humans, as well as habitat loss due to fishing and other human activities, the report said.
How many dolphins get caught in tuna nets?
According to the assessment, 80,000 dolphins may be accidentally caught every year by tuna gillnetting boats, with india contributing 10,000 dolphins annually. According to the report, approximately 4.1 million dolphins may have been caught since tuna gillnetting began in the Indian Ocean.
“Tuna fishing is a major cause of dolphin strandings, and it is imperative that the international community takes immediate action to reduce the number of dolphins being caught in this way,” said the study’s lead author, Dr. Ramesh Kumar, from the Wildlife Conservation Society (WCS) in New Delhi, India. “This is the first time that a comprehensive assessment of the impact of tuna fishing has been carried out in a large-scale, long-term study.
We hope that our findings will be used as a basis for further research into the impacts of this form of fishing on dolphins and other marine mammals.” .
How many dolphins are killed by tuna fishing?
The researchers report that roughly 80,000 dolphins are now killed as bycatch annually. In the tropics of the eastern Pacific Ocean, fishermen have long used dolphin schools as living fish finders, signaling a tuna fishery in the area.
In the study, the researchers analyzed data from the International Union for the Conservation of Nature’s (IUCN) Red List of Threatened Species, which is used by governments around the world to determine which species are at risk of extinction.
They found that the number of dolphins killed for their fins has been steadily increasing over the past two decades, with the largest increase occurring between 2000 and 2010.
How many dolphins are killed each year?
More than 100,000 dolphins, small whales and porpoises are killed each year. A shocking new report released today reveals that more than 100,000 dolphins, small whales and porpoises are slaughtered globally in hunts each year, many of which are illegal.
The report, released by the International Fund for Animal Welfare (IFAW) and the Wildlife Conservation Society (WCS), is based on data collected by IFAW, WCS and other conservation organizations. “This report is a wake-up call for all of us who care about the world’s oceans and wildlife,” said Paul Spong, Executive Director of the IFAW.
“We need to do everything we can to stop the slaughter of these animals, and we must do it now. This is not just a moral issue, it’s an economic one as well. If we don’t act now, we will have to live with the consequences for generations to come. We can’t afford to wait any longer.
How many dolphins are caught in bycatch?
Less than 10 individuals of the vaquita are left in the northern Gulf of California due to bycatch in gillnets, and the extinction of the Yangtze River Dolphin is likely due to this. Roughly 300,000 whales and dolphins are killed each year for their fins and blubber.
“This is the first time in history that a species of marine mammal has been wiped out in such a short period of time, and it is a tragedy for all of us who care about marine mammals,” said Dr. David Macdonald, Director of NOAA’s National Marine Fisheries Service. “We will continue to work with our partners in Mexico and the U.S.
How does fishing affect dolphins?
A global effort to reduce whale and dolphin bycatch involves catching fish. At least 300,000 whales and dolphins are killed each year because of entangled fishing gear. The International Union for Conservation of Nature (IUCN) and the International Fund for Animal Welfare (IFAW) are working together to develop a global action plan to tackle the problem.
The plan is based on a set of recommendations from the Intergovernmental Panel on Climate Change (IPCC), the World Wildlife Fund (WWF), and WWF-UK. It is expected to be completed by the end of the year and will be presented to the UN General Assembly in New York in September.
How many whales are killed by fishing nets?
Whales can suffocate or starve after getting tied up in fishing gear. An estimated 300,000 whales, dolphins and porpoises a year die after being injured in nets or entangled in lines, according to the International Fund for Animal Welfare (IFAW). “It’s not just a problem for the fishermen, but it’s a huge issue for all the marine life that lives in the area,” said IFAW’s marine mammal program manager, David Macdonald, in a statement.
