What country has the most scallops?

I'm curious to know, which country boasts the largest population of scallops? Is it a maritime nation with vast oceans and coastlines, or perhaps a country with a strong focus on aquaculture and seafood farming? It would be fascinating to understand the geographical and economic factors that contribute to this country's abundance of scallops. Additionally, I'm wondering if there are any specific regions within this country that are particularly renowned for their scallop production.
