Main Overfishing Statistics

  • Approximately 90 percent of the world’s fish stocks are either fully exploited, overexploited, or depleted 
  • Overfishing has caused the global fish biomass to decline by 35 percent since 1974 
  • One-third of the world’s assessed fish stocks are currently overfished 
  • 61 percent of the world’s high-seas fishing grounds are experiencing overfishing 
  • The world’s fishing fleet is around 2.5 times bigger than what the oceans can reasonably support 
  • It is estimated that overfishing has caused the loss of 90 percent of large predatory fish populations, such as sharks, tuna, and marlin
  • Every year, approximately 32 million metric tons of fish are caught illegally, unreported, or unregulated
  • Overfishing threatens the livelihoods of more than 200 million people who depend on fishing for their income and sustenance 
  • The economic losses resulting from overfishing are estimated to be around $80 billion annually
  • The global seafood industry could lose up to $10 billion by 2050 if overfishing continues at current rates

Approximately 90 percent of the world’s fish stocks are either fully exploited, overexploited or depleted (FAO)

This statistic reveals the widespread pressure on fish populations, indicating that their exploitation levels are at or beyond sustainable limits.

There’s an overcapacity of fishing vessels, indicating a mismatch between fishing efforts and the sustainable limits of marine resources.

It is estimated that overfishing has caused the loss of 90 percent of large predatory fish populations, such as sharks, tuna, and marlin (Nereida Marine Education)

The world has to realize the severe impact of overfishing on top predators, disrupting marine food webs and ecosystem balance.

Every year, approximately 32 million metric tons of fish are caught illegally, unreported, or unregulated (Pew Charitable Trusts)

This figure exposes the extent of illegal and unregulated fishing activities, contributing to overfishing and undermining conservation efforts. At this rate, there’s no way the marine wildlife will be sustained over the years. 

Overfishing threatens the livelihoods of more than 200 million people who depend on fishing for their income and sustenance (FAO)

Understanding these statistics demonstrates the socioeconomic consequences of overfishing, emphasizing the vulnerability of coastal communities reliant on fishing.

The economic losses resulting from overfishing are estimated to be around $80 billion annually (The World Bank)

Despite the numbers, it’s hard to truly quantify the substantial economic impact of overfishing, encompassing reduced fisheries’ revenues, job losses, and ecosystem damage.

The global seafood industry could lose up to $10 billion by 2050 if overfishing continues at current rates (Nereus Program)

Understanding the forecasts of the potential long-term financial consequences of sustained overfishing, urging for sustainable management to avoid economic losses.

Large-scale industrial fishing vessels account for 70 percent of global fishing efforts but catch only 40 percent of the fish (WWF)

There’s a disproportionate impact of industrial fishing on fish stocks, highlighting the inefficiency and unsustainability of specific fishing methods.

Bycatch, the unintentional capture of non-target species, accounts for about 40 percent of global marine catches (Fish Forward)

Numerous organizations studied bycatch, which is the wasteful capture of marine life that is discarded or lost.

It is estimated that 90 percent of the world’s large predatory fish populations have been wiped out due to overfishing (National Geographic)

This staggering percentage showcases the dramatic decline of apex predator populations, indicating the cascading effects on marine ecosystems and biodiversity.

The global population of Atlantic bluefin tuna has declined by more than 85 percent since the 1970s (Monterey Bay Aquarium)

It has been decades, yet this high figure underscores the severe depletion of a highly prized fish species, primarily driven by overfishing and high market demand.

Overfishing has led to a decline of 97 percent in the population of European eels over the past few decades (IUCN)

This statistic illustrates the devastating impact of overfishing on specific species, contributing to their critical decline and jeopardizing their survival.

The Mediterranean Sea has one of the highest overfishing rates globally, with 93 percent of its assessed fish stocks being overexploited (WWF)

Given the circumstances, there’s an urgent need for improved fisheries management in the Mediterranean region to prevent further depletion of fish populations.

Overfishing contributes to the destruction of coral reefs, as excessive fishing disrupts the delicate balance of marine ecosystems (WWF)

Aside from the apparent devastation that overfishing causes, we must also consider the indirect impacts of overfishing, as the removal of crucial fish species can hinder the ability of coral reefs to thrive and recover.

It is estimated that nearly one-third of all fish harvested globally are used for purposes other than direct human consumption, such as fishmeal and fish oil production (FAO)

While this crisis is already pushing possible extinction of certain breeds, this statistic sheds light on the complex dynamics of the seafood industry, revealing how fish are often extracted for non-food purposes, exacerbating overfishing pressures.

The population of Atlantic cod off the coast of Newfoundland, Canada, collapsed by 99 percent due to overfishing in the early 1990s (WWF)

What was once a thriving fishery has suffered devastating ecological and economic impacts.

Large-scale bottom trawling, a destructive fishing method, affects about 20 percent of the world’s seafloor (WWF)
