I have all the silver kelp areas open since the beginning of summer and have checked all areas it's supposed to spawn in. It's not there I've checked everyday it's now fall day 5 and still nothing.

I recently found them in the silver area during winter. I don’t know…but maybe it’s seasonal? You may also need to wait a few days for stuff to respawn. I learned today that if you keep clearing the ocean floor, it doesn’t regen as fast or as well.

They aren’t seasonal, but they do look a lot like pacific oysters when they are still embedded in the sand.

How deep are you going? I found my first two today. I’m at about 30m deep. If I’m not mistaken
