Buddhism releases turtles. Sea turtles are carnivores. Is this release good or evil?

Releasing animals is a very meritorious thing in Buddhism, which not only accumulates merits for yourself, but also accumulates blessings for your children. The released animal can be any creature in nature, and the tortoise is just one of them. Therefore, people who want to buy turtles for release should be Buddhist believers, believing that releasing turtles can accumulate merits for themselves and their children.
