According to Stanford University; a collapse of a fishery population is defined as 90% or more of the original number of that species has disappeared, starting from their original, sustainable baseline population.
Now that the definitions are understood, let’s apply them to just a few of the many specific examples. The following list is not by any means complete but serves to provide a meaningful guide so that a general understanding of the problem can be grasped by the average person.
WHALE FISHERY COLLAPSED
ADULT TUNA, HALIBUT FISHERY COLLAPSED
Such overfishing has resulted in severe damage to stocks. “Japan’s huge appetite for tuna will take the most sought-after stocks to the brink of commercial extinction unless fisheries agree on more rigid quotas” stated the WWF. Japan disputes this figure, but acknowledges that some overfishing has occurred in the past.
SCALLOPS, SHARKS FISHERY COLLAPSING
OYSTER FISHERY COLLAPSING
Where fresh water rivers enter the ocean is a zone that is supposed to harbor and support the cradle of life. Many ocean species depend on the river estuaries for a part of their life cycle. But due to unsustainable modern chemical based agriculture and living methods, rivers have become death zones. Where rivers enter the oceans, oceanic dead zones are growing at the mouths of those rivers, expanding in size and growing in number each year. Oceanic animals, fish and other species are getting sick and dying. As the ocean dead zones and garbage gyres grow, the oceans are becoming more and more polluted, acidic, radioactive and warmer, thus moving towards total global life extinction, slowly but surely.
SALMON FISHERY COLLAPSED
Indians used to catch and then dry the salmon by the multiple wagon load for the winter. But that all ended when the dams went in, permanently blocking all migrating fish from going to their spawning grounds. As each dam was put in a river, the salmon disappeared. Today, there are only a miniscule small number of fish returning compared to what used to be there. Sometimes there is only one run compared to the former four runs that went on throughout the year, and that one small run needs the help of a hatchery to even survive at all.
Up to 75% of the former spawning habitat of the many and varied species of salmon has disappeared, and in cases of salmon who spawn at high altitudes in the spring, 100% of their habitat is now completely out of reach, behind dams. The spring salmon runs are now completely gone on all rivers with dams.
COD, HERRING, SARDINES FISHERY COLLAPSED
SEA BIRD POPULATION COLLAPSE
Kathy Molina, biologist: “This should be just a cacophony of Caspian terns, and gull-billed terns and skimmers. They should all be coming in with food, feeding their chicks, vocalizing to their mates or their chicks. This is really quiet.”
TURTLE POPULATION COLLAPSED
Annual mean zone-level nest density declined significantly (-28%; 95% CI: -34% to -21%) between 1989 and 2006 and declined steeply (-43%; 95% CI: -48% to -39%) during 1998-2006.

Buy sustainable seafood. By purchasing MSC-certified seafood products, consumers, retailers, and traders are helping to encourage and reward responsible fisheries. Without the MSC label, your seafood may well stem from illegally fished or overfished sources. Take a look at our seafood guides today!

Eutrophication/Dead Zones Tipping Point
The number and size of dead zones in the world’s oceans are growing and spreading wider.
Effect of eutrophication on marine benthic life
Wikipedia; “Eutrophication is an increase in chemical nutrients, typically compounds containing nitrogen or phosphorus, in an ecosystem. It can result in an increase in the ecosystem’s primary productivity (excessive plant growth and decay), and further effects including lack of oxygen and severe reductions in water quality, fish, and other animal populations.
The biggest culprit are rivers that empty into the ocean, and with it the many chemicals used as fertilizers in agriculture as well as waste from livestock and humans. An excess of oxygen depleting chemicals in the water can lead to hypoxia and the creation of a dead zone.
Surveys have shown that 54% of lakes in Asia are eutrophic; in Europe, 53%; in North America, 48%; in South America, 41%; and in Africa, 28%. Estuaries also tend to be naturally eutrophic because land-derived nutrients are concentrated where run-off enters the marine environment in a confined channel.
The World Resources Institute has identified 375 hypoxic coastal zones around the world, concentrated in coastal areas in Western Europe, the Eastern and Southern coasts of the US, and East Asia, particularly in Japan. In the ocean, there are frequent red tide algae blooms that kill fish and marine mammals and cause respiratory problems in humans and some domestic animals when the blooms reach close to shore. (red tide algae thrive in chemical/nutrient rich waters that come from agribusiness and sewage runoff from cities)
In addition to land runoff, atmospheric anthropogenic fixed nitrogen can enter the open ocean. A study in 2008 found that this could account for around one third of the ocean’s external (non-recycled) nitrogen supply and up to three per cent of the annual new marine biological production. It has been suggested that accumulating reactive nitrogen in the environment may have consequences as serious as putting carbon dioxide in the atmosphere.”
OCEAN RADIATION TIPPING POINT
The biologists could NOT find any bacteria or virus to blame. Science is about looking for cause and effect.. Yes, it could be disease. This was ruled out. Yes, it could be methane, but could that be a cause across thousands of miles of ocean? What is much more likely as a root cause, because there is a definite release of HUGE amounts of radiation, and then right after that, a massive die off of sea animals happened, plus high radiation readings in seaweed, plankton and algae were measured, is low level radiation, consisting of up to 9 tons of 1,200 man made radioactive elements that came out of Fukushima on 3/11.

As the ocean blanket/web of life unravels, because one species may support a dozen or a hundred other species, the rate of extinction of species will gather speed and momentum, until a global tipping point is reached, beyond which there is no return.
Geologically speaking, all life on Earth is being extinguished in a nano second. What right do humans have to deprive countless future generations of life? What right do humans have to take away the jewel like miracle of life on this planet?
