@Pckts I agree with you and @KRA123 about Tusk, he's very ripped and athletic, my guess he also has a larger frame but simply isn't as stocky as the others mentioned. After the Aju fiasco I'm holding any weights estimates, though.
I was hoping that with Reprocon in the area we'd get more captures as they are actively trying to increase their semen stock for jaguars all across the Pantanal. So far we only have Aju. Panthera had been performing captured at la Aurora so I wonder if maybe they are focusing on Llanos jaguars at the moment. If that was the case I wouldn't be mad at all, we desperately need recent data on this population. Nonetheless, we should remain in the lookup because we never know if any of these organizations might decide to track any of the large males from PJ for data collection purposes by collaring them. These males are still in their prime and will be for a while, so there's no rush, we just ought to cross our fingers. 
Sorry if this was established earlier in the thread, but was Lopez actually confirmed at 148 kg? I thought he bottomed out a 136 kilo scale so they guesstimated him at 148 kg, or something like that. And what was the deal with MM's widely fluctuating weights?
@Balam
About the Reprocon inspection in PJ, Reprocon is only in that area to capture animals in bad conditions and take care of them through the tough times pantanal is currently found. Obviouly if they run into male jaguars in tough situations as we saw with Aju along with the treatments and care they will collect their semen for the Caatinga and Atlantic Forest population's sake/good. Reprocon's main semen collection place focus to be introduced for Atlantic Forest and Caatinga jaguars in the future in case things go really really bad for those populations in the future is still around Passo do Lontra, Fazenda Barranco Alto and other areas of MS. If those jaguars currently in PJ isn't limping nor in bad conditions through the firings damages Reprocon isn't gonna capture them cause their focus there is to help the animals. And there's also a large unknown jaguar Gediendson captured that I am still really intrigued about. @KRA123 During the procedure of the weighing of Lopez the weighing machine quickly reached its limit of 136 kg meaning he was way larger than that size and the fiscalization of his weighing procedure was done by Sandra Cavalcanti in person which knows a huge deal about jaguars weight and sizes. So the 148 kg for Lopez is accurate. About Matheus Manco his last capture in 2019 he was very thin as you may know but I am not sure about that occasion since Onças do Rio Negro didn't give much details about his last capture neither his weight was given, but his first capture in early 2018 Matheus Manco's weight was straight up 134 kg at 4 years old.

He bottomed at 136 kg and then the biologist Sandra Cavalcanti who was among the team that performed the capture gave the final weight estimate of 148 kg, she's an authority in jaguars and has released several peer-reviewed studies on jaguar ecology for more than two decades, so her estimates hold value. You can read more of her work here. Only the biologists who were present in that capture, including Hoogesteijn, know the needy greedy of the capture itself, so if it was published in a scientific paper it remains as the official weight.
@Dark Jaguar I noticed we basically answered the Lopez question at the same time lol. Anyways, if you could tell us more about that unknown male Gedienson mentioned that would be great, it's my first time hearing about it.
And indeed, the reason Aju was captured was due to him limping on the ground due to the wounds from the fire on his paw, so as you said let's not hold our breath on them capturing Edno or Balam when they are in such pristine condition.

From Hoogestejin To start with the discussion, nobody can know the weight of the stomach content of a jaguar, unless he kill it, open the stomach and weight the content, then this is a interminable and bizantine discussion. A jaguar is able to eat that weight in meat [about the 10-15 kg figure], but the bait used do not had even the forth part of that weight (fish). You can thell these to the expert. [i] [i]The scale that we had in that moment at hand, was in pounds and reached the 300 pounds, we place the jaguar to weight him and reached the top of the 300 pounds, with strength, that means that weighed above that, and then the investigator Sandra Cavalcanti, with great experience in capture and evaluation of jaguars in the Pantanal, determined that the weight of that huge jaguar was about the 148 kg, and I was there and trully it was very big. I copy to you a publication from me about the comparison of weights and measurements of jaguars and other publication where I am in the picture with this jaguat thet we tagged 148. [/i][/i]" Here is a 315lb or 142kg Jaguar as well
@Balam
I am already trying to get in contact with Gediendson to know his size, hopefully he'll answer and also there's a few other jaguars he captured in the past I don't know much about, if you see in Reprocon's page there's a compilation of males who's semen was collected and a few of them I never saw before.
Here's the comparison image of Edno and Adriano that I had wanted to post earlier.
 *This image is copyright of its original author For comparison purposes, I scaled them both to approximately the same head length. This may very well not be the size they actually are relative to each other, but the difference in their build is evident.
@Balam @KRA123 @Pckts
OFF TOPIC. Since the recent topic here last night was pretty much about sizes I'd like to take advantage of the moment and ask you guys a size estimate for this unknown male specially cause there's a person near him so we could compare him with. how big do you guys think he is and bear in mind I dropped a comparison with 124 kg Cotim male not too long ago and despite the slight different angles and a bit of camera distance from one photo to the other, the size difference between him and Cotim still screams specially in body length. I also noticed he could have been PROBABLY captured for being taken care of due to the firings, I don't see his forearm swollen and greyish due to the loop trap as happens when they captured that way due to the struggling they do to set free and by charging attempts against the researchers, you can notice it on Cotim male's case on his right forearm a greyish stain made by the trap loop. So the unknown male was probably sedated very very recently for being taken care. I see he is a long male in body length and for me he is 130 kg. How many kg would you guys estimate him??  *This image is copyright of its original author Him and Cotim compared. 124 kg Cotim male  *This image is copyright of its original author Unknown male. *This image is copyright of its original author
@Dark Jaguar it's hard to tell just by looking at the picture, although he looks like he has some stomach content, I'd say around 5 kg of content just by gaging. I'll be modest and say 120-128 kg empty. If you really want to find his weight, try to ask one of the vets that was present in the capture rather than Gediendson himself, I always have more luck with the other vets.

It seems like this male is gonna get into the same box of mysterious captured jaguars we don't know their sizes, box which also includes Rogério cerrado male, Zezão, Picolé, Dale, Daryl, Caiman, Milagre, Fião, Juma, Marruá, Wendy, Fera, Alice, Selema, Linda... frustrating.
