The Reprocon team is there at the moment so hopefully they'll capture more jaguars. It'd be a dream if they can capture Edno, Aju, Balam and Pheonix.
Jaguar #61 btw.
Gediendson just confirmed this jaguar to be Aju, so we have his weight!
*This image is copyright of its original author
So Aju happens to be smaller than Ruxu and not in the same size class as we initially thought.
I expected Aju to be larger than just 110 kg, and at least by that photo he doesn't look in bad conditions ( in terms of size ) like Ousado and many other jaguars rescued, he was probably rescued before the fires started doing major damages to him.
Are you positive this is Aju?
I'd confirm with Paul Donahue

Yes. that's him.
Who confirmed it was him?
His forelimbs and neck pattern matches exactly like Aju's and also Check Balam's post right above mine, she said Gendiendson also confirmed it was him.

I've seen the post but I don't see where its confirmed to be Aju. I'd be curious who told Gediendson that it was Aju as those names are given by the ID project usually when the cat is first spotted.
Also, which images are you using for comparison?
The image shown has most of his neck, body and limbs covered.
@Pckts in the post he says this jaguar is named Aju, if you look closely to the videos of the capture you will see that his body does resemble that of Aju.
I think what's nice about knowing that he "only" weights 110 kg is that you saw him in person and even you said he wasn't too far away from the size of the lionesses and tigresses you've seen irl as well. So like Dark Jaguar said it gives you an idea of the dimensions that very large males like Edno or Ghost would have. These cats are pretty big.
Look closely to what you can see from the capture pic bellow and compare those spots and patterns WITHOUT MISSING ONE to the pic of Aju side by side, Becareful towards the curves of the body it might trick you, when you spend a few moments looking into detail at what you can see in both pics, you'll soon notice its him.
Those jaguars up north are known to the guys who captures them as well. for example Jorge knows Balam, Edno...

A side note, Aju was sighted after the fires in late August and not said to be in bad health, sad to see he got injured.

The neck is matchable to me, thats why I said becareful with the curves, that area you can take the top of the tiger stripe of both pics and link them, also the tiny little spots bellow the tiger stripe matches too, that is the moment you gotta look really careful in details.
I joined SCI and now have access to their Record Books.

DESCRIPTION (male) South American jaguars are 7-8-1/2 feet in length (2.1-2.6 m), including 18-29 inches (46-74 cm) of tail, stand 27-30 inches (68-76 cm) at the shoulder and weigh 200-230 pounds (91-104 kg), with some individuals considerably larger. Females are approximately 25 percent smaller than males. The largest jaguars are found near the equator, their size diminishing to the north and south. This is the opposite of many other mammals, which tend to decrease in size toward the equator.
The South American jaguar is the largest cat in the Western Hemisphere, much larger than the jaguar of North America or the cougars from either continent. The largest jaguars of all-heavily built, deep-bodied, with massive forequarters-are found in the Mato Grosso region of Brazil and adjacent parts of Bolivia. The coat is yellow to reddish-yellow with black spots that form square-shaped rosettes on head, neck and legs. The underparts are white or light buff with large black blotches. The tail is relatively short, the head is large and broad and the large yellow eyes are placed well forward.
BEHAVIOR Solitary and territorial, the male is a wanderer with a home range twice the size of a female's and overlapping those of several females. There is no fixed breeding season. The female probably mates every 2-3 years, bearing a litter of 1-4 kittens that remain with her for about two years. Life expectancy 15 years, although captives have lived as long as 22 years.
Entirely carnivorous, it preys mostly on capybara, deer and peccaries, also on sloths, tapirs, fish, caimans and snakes. Often kills domestic livestock, which has made it unpopular with ranchers and has led to its persecution. A good tree climber and an excellent swimmer; unlike most cats, it is fond of water. May be diurnal or nocturnal, depending on the presence of humans. Eyesight and hearing are excellent, sense of smell reasonably good. As a "great" cat, the jaguar is able to roar, but its usual vocalization is a series of deep, raspy, coughing grunts.
HABITAT Forests, preferably dense and especially near rivers or swamps. Also in open country if prey animals are plentiful.
DISTRIBUTION Throughout South America in suitable habitat, except for the extreme south, but primarily in Venezuela, Brazil and Bolivia.
Outside South America, it is found in Central America and Mexico.
REMARKS The South American jaguar is a magnificent animal, the "king of the rain forest," and one of the very top hunting trophies of the Americas or of the world. Any adult male is a fine trophy, but securing one can be difficult. There are several methods. One is by calling, especially at night from a blind or machan. Another is by baiting; after a bait has been hit one can either sit by it at night or follow the jaguar's trail with a pack of dogs. The last can be wet, miserable work during the rainy season, with the dogs swimming much of the time and the hunters following as best they can on foot or horseback, or even by dugout, until the final chase, when all participants are likely to be in the water. Smaller males and most females tend to tree when the dogs get close, but bigger males are likely to stand and fight the dogs on the ground, which can be an unforgettable experience for all concerned. A properly conducted jaguar hunt can be one of the world's great adventures.
TAXONOMIC NOTES Eight subspecies of jaguar are listed, three in South America and five in North America. South American subspecies are: onca (Amazon jaguar), from the Amazon and Orinoco river basins; peruviana (Peruvian jaguar), from Ecuador, Peru and Bolivia; and palustris (Parana jaguar), from southern Brazil and Argentina. We do not separate them.
STATUS In parts of South America, jaguars are plentiful and detrimental to livestock and may lawfully be hunted. Nonetheless, all jaguars are listed as endangered by the USF&WS (1972) and are on Appendix I of CITES (1975).

DESCRIPTION (male) Adult North American jaguars are 6-8 feet (1.8-2.4 m) in length, including 18-24 inches (46-61 cm) of tail. Shoulder height 25-30 inches (64-76 cm). Weight 100-160 pounds (45-75 kg), sometimes more. Females are about 25 percent smaller than males. Chromosome count is 38.
The jaguar is the largest cat in the Western Hemisphere. About the same length and height as the cougar, but more compactly and powerfully built. The coat is yellow to reddish-yellow, with whitish or light buff underparts. There are black spots on head, neck and legs, and large black blotches on the underparts. The back and sides have large black rosettes with one or more black spots in the center. The tail is relatively short, with strong black markings toward the tip. Black, or melanistic, individuals are fairly common, but their spots can still be seen faintly.
BEHAVIOR The male is solitary and territorial, a wanderer with a home range that is twice the size of a female's and will overlap those of several females. Breeding usually takes place in the spring in northern areas, but there is no fixed season in the tropics. Females mate every 2-3 years, bearing a litter of 1-4 kittens that remain with the mother for about two years. Full growth and sexual maturity are reached in 3-4 years. Life expectancy about 15 years, although captives have lived as long as 22 years.
Jaguars are entirely carnivorous, preying largely on peccaries and deer, but also on smaller mammals, fish and snakes. They often kill domestic livestock, which has made them unpopular with ranchers and has led to their persecution.

Eyesight and hearing are excellent, sense of smell reasonably good. As a so-called "great" cat, the jaguar is able to roar; however, its usual vocalization is a series of deep, raspy, coughing grunts.
HABITAT Forest, preferably dense and near rivers or swamps. Also in open country if prey animals are plentiful there. Found in scrub and desert in northern parts of its range.
DISTRIBUTION Mexico and Central America. Wanderers occasionally occur as far north as Arizona, New Mexico and Texas.
Also found throughout South America, except in the extreme south (South American jaguars are larger than those in North America).
TAXONOMIC NOTES Eight subspecies of jaguar are usually recognized, five from North America and three from South America. The North American subspecies are: arizonensis (Arizona jaguar) from Sonora, Arizona and New Mexico, pale buff in color with rosettes broken into spots; hernandisii (Pacific Coast jaguar) from a narrow strip along the Pacific coast from Sonora to Oaxaca, with broken-up, barely perceptible rosettes; veraecrucis (Gulf Coast jaguar) from the coastal forests along the Gulf of Mexico from Texas to Veracruz; goldmani (Yucatan jaguar) from the Yucatan Peninsula, with a bold, intense color pattern; and centralis (Central American jaguar) from Guatemala to Panama and extending into Colombia in South America, a small form with distinct rosettes. All North American subspecies are combined for record-keeping.
STATUS In parts of Mexico and Central America (and also in South America), jaguars are plentiful and detrimental to livestock, and may lawfully be hunted. Nonetheless, all jaguars everywhere are listed as endangered by the USF&WS (1972) and are on Appendix I of CITES (1975). They may not be imported into the United States, which is unfortunate for U.S. residents, as the jaguar has always been considered one of the top hunting trophies of the Americas and of the world.
REMARKS The University of Mexico has been authorized by the Mexican government to conduct a jaguar study program whereby a limited number of jaguars are darted and tranquilized, photographed, measured, aged, fitted with radio collars and revived so that their movements and numbers can be monitored and evaluated. The jaguar is baited and/or trailed by a pack of dogs until it climbs a tree where it can be darted. A wildlife biologist provided by the university or an official of the biosphere reserve accompanies the darting expedition, and care is taken to assure that the jaguar is not harmed. For a fee (which is used to support the program), sportsmen are permitted to take part in these non-lethal hunts and to fire the dart gun. This program is coordinated in Mexico by United for Conservation, a Mexican non-profit organization directed by SCI member Carlos Manterola. In the early stages of this program it was coordinated by the late David Hanlin.
SCI accepts Record Book entries for jaguars (and incidental cougars) darted as part of this study, and uses body measurements taken by the field biologist to arrive at the score.

Nonetheless, all jaguars everywhere are listed as endangered by the USF&WS (1972) and are on Appendix I of CITES (1975). They may not be imported into the United States, which is unfortunate for U.S. residents, as the jaguar has always been considered one of the top hunting trophies of the Americas and of the world.
REMARKS The University of Mexico has been authorized by the Mexican government to conduct a jaguar study program whereby a limited number of jaguars are darted and tranquilized, photographed, measured, aged, fitted with radio collars and revived so that their movements and numbers can be monitored and evaluated. The jaguar is baited and/or trailed by a pack of dogs until it climbs a tree where it can be darted. A wildlife biologist provided by the university or an official of the biosphere reserve accompanies the darting expedition, and care is taken to assure that the jaguar is not harmed. For a fee (which is used to support the program), sportsmen are permitted to take part in these non-lethal hunts and to fire the dart gun. This program is coordinated in Mexico by United for Conservation, a Mexican non-profit organization directed by SCI member Carlos Manterola. In the early stages of this program it was coordinated by the late David Hanlin.
SCI accepts Record Book entries for jaguars (and incidental cougars) darted as part of this study, and uses body measurements taken by the field biologist to arrive at the score.
Excellent! Nice to see this records and they confirm what I've been saying for a whole about Chaco jaguars being among the largest as well @peter you might want to take a look at those measurements.
I also wonder which region of Colombia those skulls belong to, but judging their sizes, I'm guessing these are Llanos individuals which is very valuable information as well.

DESCRIPTION (male) South American jaguars are 7-8-1/2 feet in length (2.1-2.6 m), including 18-29 inches (46-74 cm) of tail, stand 27-30 inches (68-76 cm) at the shoulder and weigh 200-230 pounds (91-104 kg), with some individuals considerably larger. Females are approximately 25 percent smaller than males. The largest jaguars are found near the equator, their size diminishing to the north and south. This is the opposite of many other mammals, which tend to decrease in size toward the equator.
The South American jaguar is the largest cat in the Western Hemisphere, much larger than the jaguar of North America or the cougars from either continent. The largest jaguars of all-heavily built, deep-bodied, with massive forequarters-are found in the Mato Grosso region of Brazil and adjacent parts of Bolivia. The coat is yellow to reddish-yellow with black spots that form square-shaped rosettes on head, neck and legs. The underparts are white or light buff with large black blotches. The tail is relatively short, the head is large and broad and the large yellow eyes are placed well forward.
BEHAVIOR Solitary and territorial, the male is a wanderer with a home range twice the size of a female's and overlapping those of several females. There is no fixed breeding season. The female probably mates every 2-3 years, bearing a litter of 1-4 kittens that remain with her for about two years. Life expectancy 15 years, although captives have lived as long as 22 years.
Entirely carnivorous, it preys mostly on capybara, deer and peccaries, also on sloths, tapirs, fish, caimans and snakes. Often kills domestic livestock, which has made it unpopular with ranchers and has led to its persecution. A good tree climber and an excellent swimmer; unlike most cats, it is fond of water. May be diurnal or nocturnal, depending on the presence of humans. Eyesight and hearing are excellent, sense of smell reasonably good. As a "great" cat, the jaguar is able to roar, but its usual vocalization is a series of deep, raspy, coughing grunts.
HABITAT Forests, preferably dense and especially near rivers or swamps. Also in open country if prey animals are plentiful.
DISTRIBUTION Throughout South America in suitable habitat, except for the extreme south, but primarily in Venezuela, Brazil and Bolivia.
Outside South America, it is found in Central America and Mexico.
REMARKS The South American jaguar is a magnificent animal, the "king of the rain forest," and one of the very top hunting trophies of the Americas or of the world. Any adult male is a fine trophy, but securing one can be difficult. There are several methods. One is by calling, especially at night from a blind or machan. Another is by baiting; after a bait has been hit one can either sit by it at night or follow the jaguar's trail with a pack of dogs. The last can be wet, miserable work during the rainy season, with the dogs swimming much of the time and the hunters following as best they can on foot or horseback, or even by dugout, until the final chase, when all participants are likely to be in the water. Smaller males and most females tend to tree when the dogs get close, but bigger males are likely to stand and fight the dogs on the ground, which can be an unforgettable experience for all concerned. A properly conducted jaguar hunt can be one of the world's great adventures.
TAXONOMIC NOTES Eight subspecies of jaguar are listed, three in South America and five in North America. South American subspecies are: onca (Amazon jaguar), from the Amazon and Orinoco river basins; peruviana (Peruvian jaguar), from Ecuador, Peru and Bolivia; and palustris (Parana jaguar), from southern Brazil and Argentina. We do not separate them.
STATUS In parts of South America, jaguars are plentiful and detrimental to livestock and may lawfully be hunted. Nonetheless, all jaguars are listed as endangered by the USF&WS (1972) and are on Appendix I of CITES (1975).

DESCRIPTION (male) Adult North American jaguars are 6-8 feet (1.8-2.4 m) in length, including 18-24 inches (46-61 cm) of tail. Shoulder height 25-30 inches (64-76 cm). Weight 100-160 pounds (45-75 kg), sometimes more. Females are about 25 percent smaller than males. Chromosome count is 38.
The jaguar is the largest cat in the Western Hemisphere. About the same length and height as the cougar, but more compactly and powerfully built. The coat is yellow to reddish-yellow, with whitish or light buff underparts. There are black spots on head, neck and legs, and large black blotches on the underparts. The back and sides have large black rosettes with one or more black spots in the center. The tail is relatively short, with strong black markings toward the tip. Black, or melanistic, individuals are fairly common, but their spots can still be seen faintly.
BEHAVIOR The male is solitary and territorial, a wanderer with a home range that is twice the size of a female's and will overlap those of several females. Breeding usually takes place in the spring in northern areas, but there is no fixed season in the tropics. Females mate every 2-3 years, bearing a litter of 1-4 kittens that remain with the mother for about two years. Full growth and sexual maturity are reached in 3-4 years. Life expectancy about 15 years, although captives have lived as long as 22 years.
Jaguars are entirely carnivorous, preying largely on peccaries and deer, but also on smaller mammals, fish and snakes. They often kill domestic livestock, which has made them unpopular with ranchers and has led to their persecution. They are good tree climbers and excellent swimmers; unlike most cats, they are fond of water. May be diurnal or nocturnal, depending on the presence of humans. Eyesight and hearing are excellent, sense of smell reasonably good. As a so-called "great" cat, the jaguar is able to roar; however, its usual vocalization is a series of deep, raspy, coughing grunts.
HABITAT Forest, preferably dense and near rivers or swamps. Also in open country if prey animals are plentiful there. Found in scrub and desert in northern parts of its range.
DISTRIBUTION Mexico and Central America. Wanderers occasionally occur as far north as Arizona, New Mexico and Texas.
Also found throughout South America, except in the extreme south (South American jaguars are larger than those in North America).
TAXONOMIC NOTES Eight subspecies of jaguar are usually recognized, five from North America and three from South America. The North American subspecies are: arizonensis (Arizona jaguar) from Sonora, Arizona and New Mexico, pale buff in color with rosettes broken into spots; hernandisii (Pacific Coast jaguar) from a narrow strip along the Pacific coast from Sonora to Oaxaca, with broken-up, barely perceptible rosettes; veraecrucis (Gulf Coast jaguar) from the coastal forests along the Gulf of Mexico from Texas to Veracruz; goldmani (Yucatan jaguar) from the Yucatan Peninsula, with a bold, intense color pattern; and centralis (Central American jaguar) from Guatemala to Panama and extending into Colombia in South America, a small form with distinct rosettes. All North American subspecies are combined for record-keeping.
STATUS In parts of Mexico and Central America (and also in South America), jaguars are plentiful and detrimental to livestock, and may lawfully be hunted. Nonetheless, all jaguars everywhere are listed as endangered by the USF&WS (1972) and are on Appendix I of CITES (1975).

The jaguar is baited and/or trailed by a pack of dogs until it climbs a tree where it can be darted.

They are up there for sure.... Almeida also knew of a 21'' Scoring skull but obviously it didn't make the SCI record book info.
They also have Darted scores but unfortunately I'm not sure how they are getting the total?
I assume it's body measurements and I'll post the description below:

Nvm, I found the form for darting measurements.
*This image is copyright of its original author
For Comparison, Here's Joker
Joker was 236 cm long (from the head to the tip of the tail), 76 cm tall, 126 cm of chest circumference, 66 cm of neck circumference
Since we don't have his Head Circumference, we're unable to get a full score. But with his body and chest he'd be 141.9" without his head but we can use Shaka's head and add it.
Shaka's Score Shaka's body measured 237 cm in length (head: 37 cm, body: 135, tail: 65) Chest circumference: 108, neck: 64
Shaka's Score is 150.3" Joker's Score w/Shaka's Head is 156.46"
*One quick side note before we compare exactly* I'm asking Edu to provide both Shaka and Jokers head circumference so we can be sure I'm using the right measurement. Because I think the 37cm is just the length of head not width. I'll confirm that when he gets back to me.
