''The Sumatran tiger weighing around 110 kg was previously caught in the Batu Ampar area, Suoh, West Lampung, Tuesday (2/7/2019). Not only did his leg rot and had to be amputated, Batua also suffered wounds on his stomach and broken his upper canines. In addition, there is a hole above the neck, on the back and between the right front legs.''

From the results of his observations when viewing Batua's activities through CCTV cameras, Rosichon revealed that these animals were very risky if released.

“Personally, I'm a little doubtful about being released. This is related to his biophysical condition (deformed right leg). Biophysics for carnivorous (meat-eating) animal groups is more complicated than for non-carnivores. There is the ability to chase, catch and kill prey. If the biophysics is not fulfilled, it cannot. "It is more risky for the tiger to live if the biophysics are not fulfilled," said the Association of Zoos throughout Indonesia (PKBSI).

Thankfuly his condition improved.

''Luckily, after the amputation and receiving treatment and intensive care at the Green Valley Conservation Institute (LK), Lampung, Batua's condition has gradually improved even though his condition is now permanently disabled. Batua is now still in isolation for the next three months for recovery.''

June 2008

BANDARLAMPUNG, JUMAT - The Ministry of Forestry, through the Directorate of Biodiversity Conservation, Ministry of Forestry, translocated or moved five Sumatran tigers or Panthera tigris sumatrae and one crocodile from Nanggroe Aceh Darussalam to Lampung. The six animals were moved to the Tampang Belimbing area to be precise in the Pengekahan Village of Way Haru Village, Tampang Belimbing District, Bukit Barisan Selatan National Park, West Lampung.

The five Sumatran tigers that are thought to have preyed on humans in the Aceh forest area will then be translated into the Bukit Barisan Selatan National Park area in Lampung.''

Veterinarian Bongot, a member of the veterinarian team who examined and supervised the health of the five tigers, said that while still under the care of the NAD BKSDA and before the translocation of the five days, they were given the initials A1, A2, A3, A4, and A5.

''A1 a male who weights 105 kg, A2 a male who weights 62 kg, A3 a male who weights 106 kg , A4 a male who weights 105 kg, A5 a female who weights 50 kg.''

''The five tigers are between 4-9 years old. When transferred, the five of them were in very good health.''


Further, Tonny said that when they arrived at Tampang Belimbing, the five tigers were not immediately released into the tropical forest of BBSNP. The five tigers will be placed in two large cages to adapt while being watched by a team of doctors or BBSNP managers. The adaptation process can take several months until the five of them are ready to be released into the BBSNP forest.

''When ready to be released, BBSNP managers and sponsors will attach a GSM Collar to each tiger before being released. This step was taken to monitor the whereabouts of the tigers.''

THE RELEASE

From the research by Ani Mardiastuti ''LESSONS LEARNED FROM THE TIGER TRANSLOCATION AND RELEASE IN TAMBLING, LAMPUNG, INDONESIA''

METHODS.

The case study

'' In June 2008, five tigers (4 males, 1 female) were translocated from Banda Aceh to Bandar Lampung, from where they were brought to and released into the Tambling zone,  part  of  Bukit Barisan  Selatan National  Park  (BBSNP).  Tambling  is  currently privately managed and collaborate with the national park’s  authorities  in  boosting  ecotourism.  The private organisation funded the entire translocation process  that  was  initiated  and  coordinated  by  the Ministry of Environment and Forestry (MEF). After a successful rehabilitation, two male tigers were released into selected sites. Of the remaining three tigers, two were kept for release at a later date, after assessing the results of the first two releases, whereas  the fifth tiger,  a  known man-eater, was deemed too risky and kept in captivity for breeding purposes.''

Of the released Sumatran tigers one male of 8 years old weighing 119 kg and other male of 4 years old weighed 74 kg.

''Of the three unreleased tigers, one male (9 year) was kept in captivity, because of a history as a man-eater. The two remaining tigers (3-year  old female and 6-year old male) were kept temporarily in Tambling for  release at a later date, if the first release was successful.

After the release, the movement of two male tigers were monitored along with their  feeding  habits. Considering their movements combined with lack of human/livestock  conflict (e.g. home-range did not overlap  human  settlements), the release  was considerably a success.''

Much like the other tables, it will be continuously updated as new weights come forward. I have also included the table from Slaght et al for point of reference:

Surprisingly the averages for both, the recent weights and Slack et al., match at around 110 kg. Old records present a higher value of 119 kg, and the combined average is close to 113 kg. The range for average weights of Sumatran tigers according to this data is 110 to 119.

To reach a middle ground, however, I will add an asterisk to explain separately in the table that those two may be males in dire or not optimal conditions. Although keep on mind that A2 was quoted as being a healthy individual in the article where the weight was published. I'd be curious to see the weight for the 185 kg male, we may be able to add it as an outlier as well.

Experience told me that many times, even news reports with claims of veterinaries are incorrect and that is why we need to double check the reports, experience in more than 17 years in the "business" is speaking here.

One webpage from a known international veterinay agency claimed that an Amur tiger radiocollared weighed 250 kg, but when I researched with two experts from the field it results that it was only 185 kg.

Other webpage claimed that a Bengal tiger captured for veterinary purposes weighed 280 kg, it resulted that it was not even weighed, just estimated.

Several records from the news papers only have ranges of weights, like a Sumatran tigress posted here, which obviously is an estimation in many cases. Other news reports don't even mention the sex of the specimens and only says "tiger". So, there are several lissues when we try to gatter figures, and from my part at least, I allways try to check with the original source or even better, the original scientists that worked in the field.

Like I said, the experiance is talking here and many of the old memebers in the forum like @peter for example, can corroborate what I am telling you.

That is a very old formula created by Stewart in 1928. He was a hunter so he only provided his conclutions, do not show what method he used for it or the sample of specimens that he used, which is crutial to check the accuracy of its conclutions. By modern standards that formula is not valid at all, and I suggest you to not waste time in trying to understand it as the results will not be reliable.
