Do jewish people eat fish

Yes, of course they do. There is a long tradition of cooking fish amongst European jews which continues to be seen today. Fried white fish,either in fine breadcrumbs or as fish balls, gefilte fish which is a marinated but uncooked flattened ball. and of course, smoked salmon. These continue to be staple protein sources within a Kosher diet, which also includes meats such as beef and chicken.
