Tuna is one of the most common and favorite foods of people. It is present in various dishes and in the gastronomy of many countries in the world. This is due to its versatility and the ease with which it is prepared. It is also due to its nutritional value; they have unsaturated fats that benefit the heart and blood vessels.
But being one of the most common fish, its excessive and unregulated consumption has led it to form part of the animals that are in danger of extinction. Of the 8 subspecies that exist, 5 are on the verge of extinction, including the Pacific bluefin tuna (Thunnus thynnus), better known as bluefin tuna. As it is highly profitable, it is marketed practically all over the world.
These fish are fascinating. They have undergone little change since the last 40 million years. They reach a swimming speed of up to 110 km / h. In addition, they travel long distances in a short time, which is why they are called pelagic. Females can hatch up to 45,000,000 eggs, each. Bluefin tuna can measure up to 3 meters and weigh 600 kg.
Japan is the largest consumer of this fish, as it is present in sushi, one of its most popular dishes. But this excessive consumption is what has led him to face an imminent disappearance. According to the calculations of the National Oceanic and Atmospheric Administration (NOAA) the population of tunas, since 1970, has been reduced by 80%. Unfortunately, although it is well known that it is in danger, NOAA itself refuses to officially include it in the list of animals at risk of extinction, due to the economic consequences that this would imply.
Marine biologists consider tuna a victim of overfishing, and although measures have been taken to try to curb this excessive consumption, much remains to be done. Fishermen in North America are restricted from harvesting more than 957 tons. Some restaurants have decided to remove this from their menus, but as it is a gourmet dish in high demand, we will have to wait to see what happens.
It is true that this is a very delicious fish, but let us bear this problem in mind and, as far as possible, avoid its consumption.
