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.
First, for the purposes of this question, I am narrowing the analysis to Jews who keep kosher, e.g. follow the dietary laws, and also ignoring any personal Allergies.
While Jews can eat some forms of seafood, they cannot eat all seafood. The kosher fishes like tuna, salmon, flounder, trout, tilapia, mahi mahi, sardines, herring, yellowtail, butterfish, mackerel, spanish mackerel, etc. present no issue. All non-fish (crabs, shrimp, prawns, octopi, squids, clams, sea urchin etc.) are not kosher and prohibited. Eel, catfish, shark, ray, and panga are considered prohibited as well.
Yes, trout is a kosher type of fish.
In order to be kosher, food has to be prepared according to the kosher-laws (see Deuteronomy ch.14). These are explained in detail in the Talmud-volume of Chullin. Fish have to have scales and fins. Shellfish are not kosher. See also:

The law of Kosher dictates that the only seafood they can eat is fish. So that rules out shellfish like clams and lobster. They go further to say that the fish must have a backbone, fins and scales.
