Question Does a trout fish have scales? In a recent discussion the subjest of what constitutes a "kosher" fish came up. I said fish with scales and fins, ie trout etc....the other person, who fishes, said trout do not have scales. Is that so?
Answer What Fish and Fowl are Good for Food?
First, let us name the commonly known unclean fish — these are scaleless fish — which are not fit for food: catfish, eels, paddlefish, sculpins, sticklebacks, sturgeons, and swordfish. These fish do not have true scales. Together with these creatures are other forms of sea life unfit for human consumption: abalone, clams, crabs, lobsters, oysters, scallops, shrimp, whale.
The complete list of fish fit for human consumption would be too lengthy to enumerate in this column. Only the most important clean fish — having BOTH scales and fins — can be named. They are: albacore, anchovy, barracuda, bass, black fish, bowfin, buffalo, carp, characin, cod, croaker, darter, flounder, gaby, grayling, haddock, halibut, herring, jack, mackerel, minnow, mooneye, mullet, needlefish, perch, pike, salmon, sardine, shad, silver side, smelt, snapper, sole, sucker, sunfish, surf fish, tarpons, trout, tuna, weakfish, whitefish.
