Tuna Overfishness: Threats, Incidental Capture

Tuna overfishness: threats, incidental capture

If the fish were like cars, the tuna would be the ocean Ferrari: elegant, powerful and made for speed. Their bodies in the form of torpedo expedite their movement through water, and their special muscles to swim allow them to navigate the ocean roads with great efficiency.

Atunes are notable and impressive wild animals. Atlantic red tuna can reach ten feet long and weigh up to 2000 pounds (more than a horse). Its specialized body shape, fins and scales allow some tuna species to swim at a speed of 43 miles per hour. Atunes swim incredible distances while migrating. Some Atunes are born in the Gulf of Mexico and travel throughout the Atlantic Ocean to feed on the coast of Europe, and then swim to the Gulf to reproduce.

These extraordinary marine animals are also an integral part of the diet of millions of people and are one of the fish of greater commercial value. Most of the market is composed of four species: the list itself represents more than half of the world tuna capture, followed by the row, patudo and white tuna. Critical extinction in critical danger only represents 1% of the world capture. Since tuna capture methods have advanced over the years, tuna conservation and management has not evolved so quickly. According to the United Nations Food and Agriculture Organization, most tuna populations are fully exploited (which means there is no room for fishing expansion) and some are already overexploited (there is a risk of collapseof populations).

According to International Seafood Sustainability Foundation,

Marking the transparency line in tuna fishing

For tuna fishing, data is more important now than ever. Most tuna populations are fully exploited, which means that, in the best case, there is little or no space for expansion and, in the worst case, they are in danger of collapsing. That is why without surveillance tuna fishing is unacceptable. Commercial tuna fishing is increasingly transparent, but it is necessary to do more

Tuna supports ecosystems and economies where. They are an apex predator and consume a wide variety of other fish, from squid to herring and sardines. This maintains populations of other healthy and balanced species. The tuna is also among the most commercial value of the planet and supports artisanal and industrial fishing equally. They are a source of abundant and affordable proteins for people around the world. Promoted by this demand and high prices in Sushi markets, fishermen use even more refined techniques to capture tuna. And some species are disappearing as a result. Although tuna provides food and support for people, it is more than just seafood. Tuna is one of the main predators of the marine food chain and maintains balance in the marine environment.

Threats

Where tuna moves, fishermen have bordered the ocean with giant networks and endless rows of fishing boats. Fishermen have resorted to high technology forms to capture tuna, including devices that attract fish in clusters so that fishermen can catch more at the same time. Many of the valuable world’s tuna species face a series of urgent threats but common to its continuous existence, such as significant decreases in the population, a poor international conservation management and high levels of illegal fishing, not declared and not regulated (pirate).

Incidental capture

Since the Yellow Fin Youth and Card Mem. The removal of these yellow fin youth before they have the opportunity to spawn could lead to less yellow fin in the long term. Although most Rabil and Patudo populations are abundant in their entire distribution area, they may be in danger of overweight if the management does not properly take this secondary capture into account.

Overfishing

According to the information collected by the International Seafood Sustainability Foundation (ISSF), several tuna populations are currently overweight, which means that adult fish is captured faster than they can reproduce and replenish the population. Pacific red tuna suffers an intense overweight, and the Atlantic path and the rod of the Indian Ocean are experiencing an overfishing with increased capture levels in recent years. Karrilete tuna, although it is quite resistant, could easily fall into a vulnerable state due to overfishing if it is handled inappropriately.

The path is appreciated in Asia for Sashimi, as well as frozen and fresh in other markets. As red tuna populations are reduced worldwide, pressure on patudo fisheries increases. Red tuna populations have decreased dramatically due to overfishca and illegal fishing during the last decades, not only peaceful red tuna, but also the atlantic and southern tuna. The decrease in the population has been largely driven by the demand for this fish in the high -end Sushi markets, and its future is uncertain.
