Great white sharks have survived over 400 million years, but now they may be in deep trouble.
Rising demands for shark products has increased pressure on shark fisheries, but little monitoring or management occurs of most fisheries. [7] Major declines in shark stocks have been recorded over the past few decades; some species had declined over 90% and population declines of 70% were not unusual by 1998. [8]
Some organizations claim that shark fishing or bycatch (the unintentional capture of species by other fisheries) is the reason for the decline in some species' populations, and that the market for fins has very little impact – bycatch accounts for an estimated 50% of all sharks taken. [17]
The average size of global wildlife populations have declined by 73% in 50 years, a new study by the World Wildlife Fund has found.. The study, titled the 2024 Living Planet Report, monitored ...
This recently exposed issue along with other overfishing issues has brought upon roughly 80 percent of the shark population decline. It has become prominent concern in marine conservation activism for millions of sharks are killed yearly at an often-unregulated expense.
Researchers have discovered evidence pointing to the first known case of a porbeagle shark — which can grow up to 12 feet long and 500 pounds — being killed by a large shark predator.
The World Wildlife Fund’s Living Planet Report 2022 found that wildlife populations declined by an average 69% since 1970. [1] [2] [3]The Living Planet Index (LPI) is an indicator of the state of global biological diversity, based on trends in vertebrate populations of species from around the world.
Great white shark sightings on the East Coast have risen in recent years. In 2023, Scripps News joined researchers off the coast of Cape Cod, deploying buoys to track great white population numbers.
