Brief introduction of cod
The scientific name of Mingtai fish is Yellow Line Cod, which is also called bighead and big mouth fish in northern China. In Pollock's big family, Pollock is not big. Generally, goods are only about 25 to 40 centimeters in size and weigh about 250 to 500 grams, and the largest can grow to 4 kilograms. Pollock also has a very prominent feature, which is the origin of the name of bighead carp.
Removing the head and viscera of cod is mainly for the sake of economic benefit. On modern ocean-going fishing boats, fishing and processing equipment is very advanced. The caught cod can enter the production line at the first time, remove the head and internal organs, and then put it in the cold storage for preservation.
