Types of Fish. Seafood commonly used in raw preparations like sushi include sea bass, tuna, mackerel, blue marlin, swordfish, yellowtail, salmon, trout, eel, abalone, squid, clams, ark shell, sweetfish, scallop, sea bream, halfbeak, shrimp, flatfish, cockle, octopus and crab.hen buying fish to serve raw, purchase fish that are labeled sushi-grade, as this type has been pretreated in such a way as to limit the risk of food-borne illnesses. This involves freezing the fish for a certain time at very low temperatures that you cannot achieve with a home freezer.
== Sushi == There is a range of types, but one of the most popular is tuna. Remember that the word 'sushi' doesn't actually refer to raw fish, but a boiled rice dish. Lots of sushi does not actually contain fish. The concern about eating sushi when pregnant is because of the fish... it's thought that these days, because of pollution, there is enough mercury in ocean-caught fish t â¦ o be a health risk, and this applies to both cooked and raw fish (mercury is a metal and does not cook out).
