If you are seafood person, highly recommend to come and shop here Kona Kampachi(fillet, collared, or whole), lobsters, oysters, etc.... Everything fresh and good price.
I and my family always stay at Airbnb when we visit big island, so we buy fish and shellfish, enjoy eating as sashimi and BBQ grilling.
By a GPS, if you input "Blue Ocean Mariculture" they lead you a wrong place, but just keep going ahead, you can find this selling place right next to Kona Sea Salt. (On Yelp, this address is correct) Front of their place, there is a parking lots. There is an order counter and you can order them, they packed with blue ice(they put the box but recommend to bring your cooler bag or box).
They don't take preorder, so first come and get. Sometimes they sold out so quick.
Well, one thing, this time we ordered two Kona Kanpachi (that usually we bought), and paid back to our Airbnb, put refrigerator, we found two packages of Kona Kanpachi fillet (one package have two fillet from one fish),,,, so total we have four fillet,,, huuuum they think one fillet means from one fish fillet!? Well, we enjoyed all seafood that we bough, so no problem but when we shop next time, we'll ask them how they count for their order.
