All About The Biggest Catfish In The World
The Biggest Catfish In The World (Brachyplatystoma filamentosum)
The Lau-lau or Piraiba Catfish (Brachyplatystoma filamentosum) is a member of the family Pimelodidae. This massive catfish also occasionally called goliath catfish, are the largest species of catfish discovered in the Amazon and Orinoco basins, and also tropical freshwater as well as brackish habitats in South America. Some species are migratory. As this massive catfish is a very popular food source, finding large ones is becoming more difficult and typically found in more remote areas of the Amazon watershed.
The Piraiba is the largest catfish species on the IGFA record books, however, there have been even larger specimens reported in the 200 kg (440 pounds) range. Others claim that this massive catfish could reach 250 kg (550 pounds) and as long as 12 feet. It is primarily caught with dead or live bait on the bottom.
This species has earned a reputation as a man-eater throughout its wide distribution in South America extending north from the Amazon as well as Orinoco River basins to as far south as Argentina. We have called this fish a river monster since it has long been feared as feeding on people.
Adult Piraiba Catfish prefers freshwater rivers and also pools, while the juveniles are typically found in brackish waters around river mouths. These massive catfish feed mainly on fish, however, the stomach contents of harvested Piraiba have been claimed to include parts of monkeys and also other mammals.
A live or dead fish fished on the bottom of a river or pool, is the preferred method of angling for the Piraiba catfish. Although they have become increasingly difficult to discover due to the increased commercial pressure they have received because of their high-quality flesh. The enigmas surrounding these massive catfish make them highly sought after by anglers in searching for a sports fishing adventure to one of the wildest places in the world.
Additionally, they are almost totally piscivorous preying on loricariids and also other bottom-dwelling fishes in nature, however, most specimens readily adapt to dead alternatives such as shrimp/prawn, whitebait, squid, mussel, strips of bigger white fish in aquaria. Adults require just a single meal weekly at most. This species is suitable just for public aquaria plus an extremely small minority of private aquarists and therefore, no recommended aquarium size.
The Piraiba Catfish prefer temperatures between about 72 °F (22 °C) and 82 °F (28 °C). The pH level should be between 6 and 8, as well as water hardness. They are carnivore and lifespan of the Piraiba catfish is unknown, however, related species might live to 15 years, Piraiba probably lives longer.
The Biggest Catfish In The World (Pangasianodon gigas)
The Mekong Giant Catfish (Pangasianodon gigas), also called Thailand Giant Catfish, is an extremely large, critically endangered species of catfish (order Siluriformes) in the shark catfish family Pangasiidae, native to the to the Mekong River basin in Southeast Asia. The Mekong catfish has since been introduced in China, Bangladesh, and also other private places throughout Asia.
Once abundant in the grand Mekong river, the Mekong catfish population has decreased considerably in last few decades. Currently, this species is taken into consideration as Critically Endangered.
The Mekong is one of the Biggest Catfish In The World, it is also one of the largest freshwater fish in the world with a possible total length up to 3 m (10 ft) and a maximum weight of over 650 pounds (300 kg). They are herbivore that might live for at least 20 years.
The color of the Mekong catfish is a light grey with silver on the top. The bottom is a white or a yellow cream color. They are the only species of catfish that do not have any teeth, which are intriguing. They have eyes that are very low set on the face. Barbels occur on the juveniles. However, as they grow older and they mature those will disappear.
This species has a strictly vegetarian diet in the wild, feeding primarily on detritus as well as algae off the bottom, however, in captivity, it will take a variety of food. Additionally, as fry, this species feeds on zooplankton in the river and is known to be cannibalistic. After roughly one year, the fish becomes herbivorous, feeding on filamentous algae, probably ingesting larvae and also periphyton accidentally. These massive catfish likely acquires its food from algae growing on submerged rocky surfaces, as it does not have any type of dentition.
The Biggest Catfish In The World (Silurus glanis)
The Wels Catfish (Silurus glanis), also called sheatfish, is a member of the family Siluridae. This massive fish is the largest species of catfish native to wide areas of central, southern, as well as eastern Europe and near the Baltic and Caspian Seas.
It has been introduced to Western Europe as a sports fish and currently found in the United Kingdom all the way east to Kazakhstan as well as China and south to Greece and also Turkey. It is a scaleless freshwater fish recognizable by its broad, flat head, wide mouth and has a thick upper body as well as the laterally flattened tail, making it extremely powerful.
The Wels is one of the Biggest Catfish In The World it is also one of the largest freshwater fish in the world with catches reported into the 600 pounds range. With a possible total length up to 5 m (16 ft) and a maximum weight of over 660 pounds (300 kg). They are carnivore that might live for at least 50 years. The Wels catfish are kept in fish ponds as food fish.
The wels catfish live in large, warm lakes as well as deep, slow-flowing rivers and has even been reported in brackish waters. These massive catfish prefers to remain in sheltered locations such as holes in the riverbed, sunken trees and etc. They consume its food in the open water or in the deep, where it can be recognized by its large mouth.
The Wels Catfish natural diet consists of live, dead fish and aquatic vertebrates, however, anglers have discovered that the wels is also quick to take artificial baits such as plugs, spinners, frog lures and even flies. Over the past decade, the wels has become extremely popular among native European anglers, as well as anglers traveling from around the globe to target this prehistoric freshwater game fish.
Reproduction Of The Biggest Catfish In The World
Mekong Giant Catfish (Pangasianodon gigas)
There is little known about its reproductive behavior in this species. As the rainy season starts the Mekong will begin to spawn and move upstream. Just the bigger ones will be able to mate as size is what determines it, not their age. They do grow faster though and most of the time Mekong catfish are able to mate by the time they are 6 years of ages.
Wels Catfish (Silurus glanis)
There is little known about its reproductive behavior in this species. The Wels Catfish males produce nests where females deposit their eggs. Males then protect the eggs until they hatch. Males grow faster and mature earlier compared to females.
The female Wels Catfish produces up to 30,000 eggs per kilogram of body weight. The male protects the nest until the brood hatches, which, depending on water temperature, could take from 3 to 10 days. If the water level decreases too much or too fast the male has been observed to splash the eggs with its tail in order to maintain them damp.http://www.animaldiscoveryonline.com/biggest-catfish-in-the-world/http://www.animaldiscoveryonline.com/wp-content/uploads/2017/12/biggest-fish-in-the-world-1.jpghttp://www.animaldiscoveryonline.com/wp-content/uploads/2017/12/biggest-fish-in-the-world-1-150x150.jpgBiggest Catfish In The WorldCatfishUnderwater AnimalsBiggest Catfish In The World,Reproduction Of The Biggest Catfish In The World,The Biggest Catfish In The World (Pangasianodon gigas),The Biggest Catfish In The World (Silurus glanis)The Biggest Catfish In The World (Brachyplatystoma filamentosum) The Lau-lau or Piraiba Catfish (Brachyplatystoma filamentosum) is a member of the family Pimelodidae.
