Unfortunately, you provided an unknown fish name. Here is the product description for 'Boar Fish' from the sources available to me: there is no mention of such a fish on the internet.
Sea bass is the commercial name for one of the species of sea bass in the carp family. In different countries this fish is known by different names: lavrak, lavrik, sea zander, sea perch, sea wolf. Sea bass inhabits the Atlantic Ocean, the Black Sea and the Mediterranean Sea.
Sea bass can reach up to 1 meter in length and weigh up to 12 kilograms. It has an elongated body, flattened laterally, and small scales. The back is usually olive-colored and the belly silver. On the back there are several fins, and on the chin a small barbel.
Sea bass feeds on mollusks and shrimp, so small bones may be present in its meat.
Sea bass is considered a delicacy. Its meat is tender, lean and with a small amount of bones. Sea bass is suitable for grilling, baking or steaming. It can be baked, fried, braised, steamed or grilled.
However, if you had another fish in mind, please clarify your request. I will do my best to provide information about it.
