Perch: Living in both saltwater and freshwater, perch meat is sweet and nutritious, helping people eat healthy, reduce headaches and aches. Soup or rice paper with perch is a very good dish for people who have just woken up; Cod: White flesh, mild flavor, providing phosphorus, niacin, fat and protein.

Swordfish; Sailfish (Marlin); Shark; Orchid fish, also known as porpoise, square-headed fish, and tilefish.

Albacore and yellowfin don't contain a lot of omega 3, so you shouldn't eat more than once a week either. It's best to go with canned low-fat tuna up to three times a week to keep it healthy. be a good source of protein.

Sea bass; Halibut; Mackerel / filet; Gobies; Sea snapper.

3.3. Wild-caught fish and farm-raised fish It is impossible to say that wild-caught fish or farmed fish are healthier. Both types may contain mercury. While wild-caught fish tends to be lower in saturated fat, fish farmed in rafts is usually richer in omega 3s.
