No commercial harvest just a rec season.

I'm in a good zone for easy to snorkeling shallow grass beds that can be abundant and we have a three month long season, July 1 through Sept. 24.

So throughout the season I pretty much have all the Scallops I want.

We have a daily limit of, per person: 2 gallons of whole bay scallops in shell or 1 pint of bay scallop meat
Per vessel: Maximum of 10 gallons of whole bay scallops in shell or 1/2 gallon bay scallop meat (1/2 gallon = 4 pints)

I imagine they are also farmed but I know nothing of it.
Regionally clams are farmed big time.
