The port of Spain is in Trinidad and Tobago.
Tico swims with his device before he is released.
International rescue teams had been looking for Tico for two months after he ran away.
Tico embarked on a journey that took him more than 4,000 km from the waters where he had been released into the wild.
An operation that spanned multiple countries and sent rescuers scampering on planes, boats and cars in a race against time to save Tico's life had a happy ending on Monday.
The veterinarians from the environment ministry in Venezuela were able to catch up with the animal.
TICO has been saved before. When he was a baby, he was found on a beach in north-eastern Brazil and taken in by a Brazilian organization.
He was released into the wild in waters off Icapui in north-eastern Brazil on July 6th after seven years of rehabilitation.
Tico's caregivers began to fear for his life a few days after he entered the water.
With Tico swimming further and further into the ocean it was decided that he should be saved.
TICO just kept going. He blew through five Brazilian states and left the Aquasis team chasing after him.
The transmitter came close enough to the surface to signal that it was off the coast of T&T.
"We thought that he was dead, or that it was just the equipment that showed up," says one of the people who received the location notification thousands of kilometres away.
Ms Carvalho and her team at Aquasis are trying to find out if Tico is still alive.
The fisherman leaped into action. It took him about four hours to find the device that was attached to the animal.
The news that Tico was alive was given to the team in Brazil.
Dr Reia Guppy said that the relief at finding him swimming close to the edge of the wall at the port turned into worry.
The assistant professor explained that the ferry was going to dock in about an hour.
Dr Guppy's team was able to get TICO out of the danger area after hijacking a fishing vessel. Tico swam off again, eluding those attempting to save him.
The team is running after Tico with a car, driving through different cities, and trying to get a boat every time they try to find him.
She says that sometimes they were trying to move faster than Tico so they could chase him. Even though the team got access to a plane, it wasn't enough to compete with the animal.
Tico entered international waters after passing Amapa.
He made his way through the waters of French Guiana. He made his way to Venezuela after the encounter with Dr. Guppy and her team.
"Tico has traveled over 4,000 km, which is amazing, flabbergasting and a novelty," says Dr. Guppy.
The longest distance from the coastline upriver to the shore was 14.24 km, according to the study.
Tico is being nursed back to health at a private sanctuary for marine animals in Venezuela.
Aquasis is working with the authorities in Venezuela to bring TICO back to Brazil.
The search for Tico has cast a spotlight on the threats facing the animals in Brazil.
These aquatic herbivores, which are listed as "endangered" in Brazil and classified as "vulnerable" by the International Union for Conservancy of Nature, give birth to babies in Brazil's tropical mangroves.
Mangroves are being destroyed as developers build on the highly sought after coastal strips.
The calf is at risk when they do that. Sometimes we can't see the mother of the newborns we rescue, so we have to return them to her.
Aquasis cares for stranded and injured manatees as well as campaigning for the preservation of the environment in which they live.
