Bluefin tuna (specifically Pacific, Atlantic, and Southern species) is widely considered one of the most heavily overfished,, driven by immense demand for sushi and sashimi. Due to high commercial value, they are caught faster than they can reproduce, often leading to population declines of over 90% in some areas.
Decades of destructive fishing has resulted in the precipitous decline of key fish stocks such as bluefin tuna and Grand Banks cod, as well as collateral impacts to other marine life.
Bluefin tuna are heavily overfished, and most experts agree that without prompt intervention, the slow-growing, slow-maturing species will become extinct. International regulation is tricky, however, since the bluefin tuna is known to migrate thousands of miles across the ocean.
The majority of the order Rhinopristiformes, which includes sawfish, guitarfish, wedgefish, and other shovelnose rays, is considered critically endangered, with 28 of its 64 evaluated species considered critically endangered by the IUCN.
The Coelacanth: The Fish That Refused to Go Extinct The Coelacanth is one of the most mysterious animals on Earth. Once believed to be extinct for over 66 million years, it shocked the world when a living one was discovered in 1938.
About 58% of fish stocks are still overfished in the Mediterranean, and total fish populations have fallen by more than a third over the past half-century. The cause of this ecological crisis: increased fleet capacity, illegal fishing, and catches of unwanted species.
Overfishing. According to information collected by the International Seafood Sustainability Foundation (ISSF), several tuna stocks are currently overfished, meaning that adult fish are being caught faster than they can breed and replenish the population.
The Permian–Triassic extinction event, colloquially known as the Great Dying, was an extinction event that occurred approximately 251.9 million years ago (mya), at the boundary between the Permian and Triassic geologic periods, and with them the Paleozoic and Mesozoic eras.
Getting enough Omega 3 is key to a balanced diet. However, one 2008 study reports that tilapia contains more Omega 6 than Omega 3, at a ratio of 11:1. High levels of Omega 6 can increase the risk of asthma, arthritis and other inflammatory conditions in humans.
Sardines from the southwest UK are a great choice thanks to healthy population sizes and a low impact fishing method. Sardines are classed as an oily fish meaning it's packed full of omega-3's and nutrients.
There are multiple reasons for the collapse of the Atlantic Cod fishery, including technology (that increased the volume of fish caught), mismanagement and poor understanding of the area's ecosystem. However, what happened with the Atlantic Cod fishery is not an exception. In fact, it may be a sign of the coming times.
The list is extensive, but some of the more popular and well-known fish species of particular concern due to their declining population are listed below.
This is the arapaima. Also known as piraruku. It's one of the largest fresh water fish in the world. It's natural bulletproof vest helps it thrive in the dangerous waters of the Amazon. The hard mineralised scales are so strong and flexible they can even withstand ferocious piranha attacks.
Salmon. There is no doubt that salmon is the most popular and best-tasting fish on this list. It is also a healthy fish. There is a discussion about whether wild or farmed salmon is the better choice.
The animal with only about 10 individuals left in the world is the vaquita, the world's rarest marine mammal, a tiny porpoise found exclusively in Mexico's Gulf of California, critically endangered primarily due to being caught as bycatch in illegal gillnets for the totoaba fish.
The "Secret 7" animals in Africa are a group of elusive, largely nocturnal, and shy creatures that are notoriously difficult to spot on safari, making them a special prize for wildlife enthusiasts, and they typically include the Aardvark, Pangolin, Serval, African Wild Cat, Civet, Large-Spotted Genet, and Porcupine. These animals have evolved secretive habits and adaptations to survive in the harsh wilderness, unlike the more commonly seen "Big Five".
