Arapaima Gigas

The arapaima (PIRARUCU) fish is one of the biggest freshwater fish species in the world. The fish can only be found in the Amazon River in South America. It is believed can reach a length of 450 centimetres and weight up to over than 200 kilograms.

The arapaima is very popular food fish and sport fishers there, a majority of caught arapaima fishes are sold and consumed in Brazil. Arapaima caught today forbidden in many regions but THE ILLEGAL FISHING still continues.

It is made hard to find large arapaima specimens today. The arapaima is a predatory fish that eats fish, birds, monkey and any other animal that it can catch. Arapaimas prefer to hunt close to the surface since they need to breathe oxygen from air, the fact that this fish need to air from the atmosphere every 10-20 minutes.

The arapaima is found in various habitats in the Amazon River, it lives in white water as well as clear water. The arapaima is egg laying mouth brooding species that tend to its eggs as well as its larvae. They will aerate the water to make sure that the eggs get enough oxygen. The pheromone makes the larvae stay close to their parent where they can be protected from predator.  

  

Giant Stingray

 

THE TRUE MONSTERS IN THE WORLD’S

Fishers and scientists announced the world's largest known freshwater GIANT STINGRAY

The giant stingray, weighing an estimated 250 to 450 kilograms was reeled in on January 2009 in Thailand (recording in National Geographic.)

The stingray's body measured 2 meters wide by 2.1 meters long. The tail was missing. If it had been there, the ray's total length would have been between 4.5 and 5 meters.

The giant stingray once overfished may be more abundant than previously thought and it may confirm the giant stingray as the heavyweight champ of the Megafishes

The Thai populations were once considered critically endangered although with the discovery of new populations the stingray's abundance appears higher than previously believed

Freshwater giant stingrays are among the largest of the approximately 200 species. They can be found in a handful of rivers in Southeast Asia and northern Australia.

Much is still unknown about the species including whether or not it can swim out to and survive at sea. The species was first described scientifically only in 1989.

Alligator Gar

THE LEGEND OF ALLIGATOR GAR 

It's a beast from the age of the dinosaurs — a monster with razor sharp teeth, armoured scales, and a nasty reputation: the alligator gar. The alligator gar is one of North America’s most unusual fish and one of the largest freshwater fish in the world. It can grow up to 10 feet long and live up to 50 years.

The Alligator gar has two rows of teeth on upper jaw like are needles, they will latch on or dig into their prey. The alligator gar has outlived the dinosaurs because it has some exceptional survival tools.

The alligator gar can breathe air from the surface allowing them to live and marches where oxygen levels are low. Alligator gar scales are rock hard. The whole back of this fish is covered with armor-like scales. Each scale is about as thick as a quarter and tough as nails.

The female alligator gar can produce over than 100,000 eggs bit the quantity of these eggs not unusual. The eggs contain that remarkable (a deadly toxin).

Many people believed that the gar gobble up highly prized sport fish like bass and redfish, so when they find a gar at the end of their line, they kill it — even if they have no use for the fish. The legend about gar wiping out sport fish and taking bites out of humans is myths. Alligator gars are opportunistic feeders, not blood-thirsty monsters. They want to spend the least amount of energy as they possibly can to consume their food.

Monster Fish of Australia

 

 SAWED OFF

SAWFISH which means (YOUNG FISH GROW in EGGS inside their MOM), Sometimes sawfish are confused with another species SAWSHARKS because their similar snout. However, sawfish are much larger than sawsharks which only grow to around 5 feet in length. Sawfish also considered in the shark group.

In Australian waters 4-7 sawfish species are found. There are freshwater sawfish like green sawfish, dwarf sawfish and the narrow sawfish. It is estimated that some sawfish species can live over than 30 years old.

In the 19^th century one of the most popular fish in the Indian River system is SAWFISH, while reported one fisherman can catch 300 sawfish in just one season. Survey in 1981 found there were no sawfish in the area.

The sawfish’s scientific name is Pristis microdon. Pristis means “saw” in Greek, and the word microdon refers to the word micros, meaning “small.”

The rostra teeth of sawfish are sometimes used for cockfights: individuals can attach the teeth to roosters’ legs to be used as spurs. This practice adds to the value of sawfish in the marketplace and Traditional Chinese medicine can use the eggs, bile, and oil of sawfish. The rostrum can also be used in religious ceremonies.

The price of a sawfish’s rostrum can add up to over $1,000 dollars. While the sale of rostrum is banned, sales still occur. Due to increased demand for sawfish fins, just one pair of fins can be sold for around $3,000 in some markets.

Monster Fish of America

MONSTER FISH OF AMERICA

Lurking in the murky depths of the world's great waterways are bizarre giant specimens of such enormous proportion and odd appearance that boggle the mind. the biggest and oldest of North America’s river monsters: the white sturgeon.

Traits

The BELUGA STURGEON the largest of the sturgeon family can grow to be 28 feet long and weigh roughly 2,866 pounds. The WHITE STURGEON was once among the largest species on Earth.

The oldest White sturgeon lived to be 106 years old, Scientists reported that the largest white sturgeon weighed1, 799 pounds. The sturgeons are defined as being anadromus since they can survive in both fresh and salt water.

The sturgeon sexually mature until they are 26 years old for female and 22 year old for male, human are the only PREDATOR to adult white sturgeon.     

Population activity and environment

Female Sturgeon can release several million eggs, but they only spawn for four to eleven years at a time, the population of STURGEON in the Kootenai River has only 20 hatching per year survive. Dams have the reason changed the river and impacted the STURGEON.

It’s is estimated that by 30 years future fewer than 50 wild born adult STURGEON will be left.

Catfish King

Catfish King
The wels catfish is the largest European freshwater fish. It is native to Eastern Europe and western Asia, but now also lives in foreign areas like the Ebro River in Spain. 

Roland Lorkowski (A German Biologist) who’s are claims to introduced the WELS CATFISH illegally to the Ebro River in 70 an. The Ebro River has the highest water flow on the Iberian Peninsula, impact that thing other countries reported adverse ECOLOGICAL IMPACT after the introduction the Wels Catfish.

        The skin on wels catfish lacks scales, contains sensory cells and contributed to respiration through oxygen absorption or carbon dioxide secretion. The wels catfish is well adapted to living in fresh water with low visibility and has small eyes.
        The life span of wels catfish caught is reported to be 22 years in the Volga Delta, the wels catfish is a nest guarding species. Mentions a wels catfish dragging a fisherman near Gyor, Hungary, under water by his right leg after attempted to grab the fish in hold. According to fisherman that catfish must have over 100 kilograms.
        In some countries like France and Spain the wels catfish is a SPORT FISH, the largest wels catfish caught in the Ebro River 2.60 meters and 112kilograms.
