How do you get scallops?

I'm curious, could you please elaborate on the process of acquiring scallops? Are they typically harvested from the ocean, and if so, what methods are employed? Are there any specific regions or conditions that are ideal for scallop fishing? Additionally, are there any ethical considerations or regulations in place to ensure the sustainable harvesting of these delicious seafood delights? I'm eager to gain a deeper understanding of this fascinating topic.
