The article does not go into large element so I am going to develop on what I used to be capable of finding elsewhere. The river is the Guapore River, which is 780 miles lengthy. The turtles had been all launched collectively, however there was a purpose for that. It’s the largest spawning website for the species and a big communal nesting seaside. In line with the Publish article 100,000 females laid their eggs on that seaside, however it wasn’t clear to me if that quantity is the present quantity or the quantity previous to the inhabitants decline. Both means, a lot of the breeding females lay their eggs on that seaside, so releasing all of them collectively is smart.
The sort is not named on the species degree (there’s a couple of factor known as the Amazon River Turtle) however the younger confirmed on a closeup on the New York Publish web site is Podocnemis expansa. They get to be fairly giant, 200 lbs is just not uncommon for them. They breed effectively in captivity, however develop slowly, so farming them for meals is not economically possible. They’re closely exploited for his or her meat and eggs, and most used for that goal come from the wild.
They do not say the place the turtles had been sourced from, however it’s a well-liked mannequin for headstart packages, the place they gather hatchlings and lift them for a 12 months or two earlier than releasing them, so the bulk in all probability got here from there.
As for conservation, the Guapore River is a stronghold for the species, it’s doing okay there, however in some techniques it’s doing fairly poorly. The Orinoco River inhabitants went from round 100,000 breeding females in 1945 to about 1,000 on the flip of the millenium. Whereas particular person populations crashed, the world inhabitants is presently safe, however solely resulting from conservation efforts like these ones. If these conservation efforts ended the species would possible be thought-about endangered or threatened.
