Conger eels are a type of fish that don't have pelvic or pectoral fins, not snakes at all. They are a great source of super-healthy omega-3 fatty acids, much like fish. A healthy level of calcium, magnesium, potassium, selenium, manganese, zinc, and iron are also present. You should expect an average of 2 to 5 kilogram of fish. Note: The weight of the seafood before cleaning or cutting determines all of our rates and billings. The kind of cleaning you select will determine the net weight at the time of delivery.
