Mekong giant catfish

The Mekong giant catfish (Pangasianodon gigas) may be the largest kind of the household Haiwelse (Pangasiidae) and among the largest freshwater fish inside the world. It happens only in the Mekong and it's because of overfishing and habitat loss as threatened with extinction.

 In Southeast Asia it truly is used as Flaggschiffart to convey the require for protection of large fish inside the Mekong. Mekong giant catfish are characterized by extremely high growth rate and are thus also taken into aquaculture programs; extent artificial breeding are typically in support of untamed stocks, but it is still unclear.


Attributes

Mekong giant catfish are similar to all Haiwelse of scales and have an elongated, laterally flattened body. Adult animals are meant incredibly robust and may also use a body time period of up to 3 meters and weigh kilos of over 300. Even though the females are longer and heavier versus the males. Mekong giant catfish are silvery-gray with blasswei├člichem stomach and now have no drawings.

 The fins are generally gray. Juveniles are dark, shiny, silvery belly and have absolutely two stripes around the flanks. Her head makes 14-21% of regular length (head and trunk without having tail) and is particularly wider than the pangasius (Pangasianodon hypophthalmus), but is not as wide as pangasius sanitwongsei. The muzzle is blunt or rounded and terminally, with slightly protruding lower jaw.

Sitting in pups in the lower and upper jaw, 1 set of two barbels as well as the eye is greater than for the opposite Haiwelsen. Have upper and lower jaw along with the vomer tiny, cone-shaped and comparatively blunt teeth. In older animals, that have reached this kind of lifetime of 30 to 50 centimeters, falling belonging to the teeth and whiskers recede, the Bartel pair to the upper jaw might be only 3 to four millimeters long, which disappears within the lower jaw completely in adipose tissue.

The eye area wander up to the height from the mouth angle down, what occurs with other type Haiwels. The gills have a really short upper and lower arm using a very elongated. Top of the arm carries three gills Reuse thorns, along with the lower 14, can be those invoved with older animals regressed practically fully.

The triangular dorsal fin has two challenging jets, the first of which is quite little and normally not perceptible from the outside, and seven, seldom eight, branched soft rays. A modest adipose fin occurs. The pectoral fins have a nice hard radiation and 10 to 11 soft rays, the ventral fins are an unbranched and 7 or 8 branched soft rays, along with the elongated anal fin, 31-35 soft rays, which are unbranched initial six or seven. Filamentous appendages can be in any of the fins. The swim bladder is unilocular and restricted towards the abdomen. The sheer number of vertebrae is 48
