SINGAPORE: The injured otter that was spotted with a deep cut on its back at a Pasir Ris Park canal last month was successfully treated on Thursday (Nov 16).
The operation was planned over three weeks by several agencies and volunteer groups of the Otter Working Group including the National Parks Board (NParks), Wildlife Reserves Singapore (WRS), the Animal Concerns Research and Education Society, PUB and Agri-Food & Veterinary Authority of Singapore (AVA).
In an email to Channel NewsAsia, Mr Sivasothi who runs OtterWatch, said that the movements of the nine-month-old female pup - who was named Aquarius - and its family were closely monitored before capturing it for treatment.
"Stress to the family was reduced by minimising the number of people on site and working relatively quiet," said Mr Sivasothi, who is also a senior lecturer of biological sciences at the National University of Singapore.
The wounded otter with seven of his family members were eventually rounded up in an enclosure at Pasir Ris Park made by NParks at around 2pm.
The see-through enclosure ensured that the otters "could view their environs and not feel confined," explained Mr Sivasothi.
A WRS vet darted Aquarius and the pup became drowsy within seconds. When it was deemed safe for the vets to approach the targeted pup, the enclosure was opened for the rest of the family to swim away.
In less than fifteen minutes, the team of WRS vets had snipped off the rubber "O-ring" around the pup's body, which had cut into the otter's abdominal muscle, and attended to its wound by applying antibiotics, said Mr Sivasothi.
After a 30-minute observation period, where the pup rested within the enclosure, the otter was released.
It rested within the enclosure and the environs for a further 80 mins before walking out across the tidal flats and then swam away.
Mr Sivasothi said this was the first time that Otter Working Group had targeted a young adult amidst its family for capture. Previous cases have only seen the group working to rescue otter pups abandoned by their families.
Wounded otter pup successfully caught, treated in first such operation

SINGAPORE - The otter pup that was spotted last month with a wound from a ring around its body was successfully rounded up and treated in a five-hour operation on Thursday (Nov 16).
The young pup was corralled along with six other members of its Pasir Ris family at Pasir Ris beach, otter watcher Jeffery Teo told The Straits Times.
Volunteers and related agencies such as the National Parks Board have been tracking the otter on site from two days ago, Mr Teo said. The pup was caught at the river mouth near Sungei Tampines and darted around 2pm after the operation started in earnest from noon.
"More than 20 people were there, including the Wildlife Reserves Singapore and NParks," he said. "NParks built a special structure to catch the otters."
The operation is the first of its kind in Singapore where a wild otter was successfully isolated, treated and released.
Multiple attempts had been made to capture the single pup, which is believed to be eight to nine months old, but it was too fast and evaded capture.
The otter pup, which was born around February or March this year, is part of a family of nine or 10 that is known as the Changi family.
National University of Singapore (NUS) biology lecturer N. Sivasothi, who heads OtterWatch, told ST that the success came after three weeks of detailed planning.
"This was an operation three weeks in the making, starting with detailed observations and evaluation of procedures," he said. "The final procedure involved corralling most but not all of the family that were investigating the operations area. Once the vets succeeded in sedating the otter, the rest were released."
Mr Sivasothi said the otters were not restrained.
"This was important to reduce stress to the family," he said. "A smooth-coated otter family stays together so a single individual can't be easily isolated."
The Pasir Ris family has 11 otters - seven were caught in the enclosure, with two of these eventually escaping. Four others evaded capture.
After the otters were rounded up in the fence-like structure, veterinarians tranquillised the otter pup, which had sustained a deep wound from what looked like a ring of metal wire spotted around its torso last month. It turned out to be made of rubber.
It is unclear how the ring got trapped around the otter. It was removed and the pup was treated on the spot. Multiple veterinarians certified it healthy before it was released back to the wild.
"They all certified that she's good to go," said Mr Teo jubilantly over the phone.

The otter watchers have been tracking the pup, which sustained a wound that was visibly worsening, for weeks.
Mr Teo has tracked Singapore's otters for more than five years and is part of the Otter Working Group, a volunteer group set up with several government agencies including NParks, the Agri-Food and Veterinary Authority and PUB last year.
On Tuesday, the same otter family had been spotted on the tarmac at Changi Airport, after heavy rain is believed to have forced them out of their holt.
