Slub shrimp is more expensive than metapenaeus ensis because it is bigger, tastes better, and has higher nutritional value, and its transportation cost is higher, and the mortality rate from water is higher, while the tail shrimp is smaller, and its taste is not as good as that at the foot of a pig, and its culture area is not as big as that of slub shrimp, so its transportation cost is lower, so it is more expensive than metapenaeus ensis.

Slub shrimp refers to Penaeus japonicus, which is light yellow with blue-brown stripes and bright blue tail tip. The carapace is thick and the frontal angle is slightly curved.
