車エビPenaeus japonicus) it produces utilizing the mineral rich deep sea water from the local Okinawa Deepsea Water Research Institute. The prawns provide an important and delicious source of income both for domestic and international consumption. The deep sea water helps Kumejima's shrimp grow healthier and tastier in protected farms around the island. You can differentiate Kuruma Shrimp from other tiger shrimp by the distinct blue hue in their tails. Before cooking the prawns are nearly translucent with stripes similar to Tiger Shrimp. Once cooked, high quality prawns turn a deep red. The shrimp are initially hatched at a centralized location near the research institute before being moved to the various farms. The photo to the left shows a breeding area. The prawns make their homes in the sands at the bottom. The sand is prepared by loosening it with farm implements before deep sea water is added. The reason they are hatched separately is so that population-damaging viruses from the ocean are avoided. Since mineral-rich deep sea water is used, the baby shrimp are healthier and tastier.
Hatchling tanks with nearly microscopic shrimp.Once at the farms, the prawns grow until they are ready for sale. With such fresh product, they are sometimes even served as sashimi (raw) on the island, though the most popular method is to grill them with a little salt.
Epoch Shrimp Farms
Harvest and ProcessingSince shrimp are active at night, traps are set out around the tanks at night. Inside the tanks are bait and lights that attract the shrimp. A simple funnel net allows them to enter, but keeps them from escaping the other end. The size of the holes in the trap allows undersized shrimp to escape and grow larger. In the morning, the traps are hauled up and the shrimp are transferred to directly into cold water containers where they go directly to the processing facility just a few meters away. The shrimp hangout in cold water that keeps them fresh and healthy throughout the quality process. At Epoch, the shrimp are sorted twice. First, they are sorted by size so that only shrimp of the same size make it into the same box. Next, prawns are checked for damage. Any damaged prawns do not become part of a live shipment. Occasionally, a few soft shell prawns are found. These prawns only occur in about 1% of the population and are extremely rare and popular. Soft-shell shrimp can be eaten whole even by those who do not usually eat shell-on shrimp. Once sorted, the shrimp are weighed and boxed with a cool pack and paper to protect them during shipment. The shrimp can live two to three days if kept cold, and can thus be shipped live around Japan. Most Kumejima Kuruma Shrimp are sent to Tokyo and other markets where they are auctioned for use at high-end restaurants. Shrimp are also flash frozen for distribution during non-peak seasons. Live Shrimp are especially sought for esebo or gifts given at the end of the year, which co-incides with their growth cycle. They are so fresh and delicious, and one of the few sea products that can be delivered live.
