Starfish as compost ingredient or soil amendment

14 years ago

Came across a friend taking a load of starfish to the dump - they're a serious predator on his shellfish farm, and are reoutinely removed and destroyed. He must've had at least 500 lbs in his truck, and would have been glad to dump them in my driveway.

I was curious what (if any) value they would have as a compost ingredient or direct soil ammendment. They don't really 'rot' when left out, so I assume they're not nitrogen-heavy. There's probably some Calcium in their shell, or maybe even Phosphorus.

Does anybody have a clue what their nutritive contribution might be?
