Any recommendations for growing Mangroves from seed?

[Dreadnaught]

I'm looking for recommendations and tips for growing Mangroves from seeds. The seed part weighs them down naturally. It also makes them easy to lodge into rock. But they float when it falls off.

Should the seeds/shoots be fully or partially submerged? If partially, how much above or below the water-line?

This is what they look like when picked.
