It turned out to be a hawksbill turtle, which is an endangered species and so on Tuesday Phuong and local officials released it back into the ocean.
According to the newspaper, last month, fishermen from nearby Quang Nam Province also released a hawksbill turtle back into the sea after finding it trapped offshore in a discarded fishing net.
The World Conservation Union classifies hawksbill turtles as critically endangered. Fishing has reduced the population of the species and driven it to the brink of extinction.
The Convention on International Trade in Endangered Species outlaws the capture and trade of hawksbill turtles and products derived from them.
