Question about fish spawning

[sonianna]

Hello everybody,

I'd like to know if anyone has an idea about the length of time between hatching and spawning for benthic fish vs a pelagic fish?

Thanks a lot!

This really only makes sense the other way around - there's no generality to what you've asked as you've asked it. There's really not much the other way around, either, but there is a concept embedded in it.

But if it's the gap between spawning and hatching, this tends to be longer in pelagic fish because they don't tend to run into each other where eggs can be laid (unless they have periodic mating runs into the shallows), so the gap of time is longer, with "find a place to lay eggs" inserted into the process.
