Description

Barley Shrimp Farm{FARM FOR PENAEID PRAWN}

The present invention relates to barley shrimp, and more specifically to a farm for cultivating barley shrimp.

The penny shrimp is a crustacean belonging to the decapod family Penidae. The scientific name is Penaeus japonicus.

The body length is about 23.5cm, and the body colors are various, such as light blue or reddish brown. The body has about 10 dark stripes horizontally from the head and chest to the caudal joint. The forehead horn is slightly curved and its tip is pointed upwards. There are 8-10 teeth on the upper edge and 1-2 teeth on the lower edge. The carapace is smooth and hairless.

These barley shrimp mainly live in places from the coast to a depth of 100m. The spawning season varies depending on the region, but in Korea it is between May and September. The newly hatched chick looks like a very small gourd with legs, but after 2 to 4 weeks, it goes through several molting changes and looks like a miniature version of the adult. Young barley shrimp move to shallow shores where they will grow. However, more than 80% of them are eaten by marine animals during migration, and the surviving young shrimp settle in bays or river estuaries. Forested coastal wetlands rich in organic matter are a favorite hiding place for barley shrimp and serve as a kind of nursery. After about 5-7 months of rapid growth, the shrimp begin their journey back to the deep sea, which takes two months. Barley shrimp lay eggs in the deep sea, and one female lays 500,000 to 1 million eggs. It is believed that most adults die soon after laying eggs.

Due to its high economic feasibility, research on aquaculture has been conducted well, and it is also farmed in Korea. It has strong vitality and can be transported long distances by placing it in sawdust moistened with water. It is distributed in Asia, including Korea, and in the Indian Ocean and Red Sea.

Patent Registration No. 10-0751198 discloses ‘a process for nitrifying water in a closed farm for barley shrimp and other shrimp.’

According to Patent Registration No. 10-0751198, a process and device for nitrifying water in a closed farm for penny shrimp and other shrimp are provided, thereby removing unionized ammonia that is harmful to larvae.

Although this prior art can remove unionized ammonia, which is harmful to larvae in shrimp farms, it has the disadvantage of not providing a comfortable environment for growing barley shrimp.

Patent registration number 10-0751198 {Registration date: August 14, 2007}

The purpose of the present invention is to create a barley shrimp farm that can provide a comfortable habitat for the growth of barley shrimp by installing a bed such as a sand plate in the culture tank because barley shrimp have an ecological habit of liking sand.

The barley shrimp farm according to the present invention includes a tank for containing seawater as breeding water;
A bed spaced a certain distance from the bottom of the tank and installed horizontally to connect both walls to each other to allow barley shrimp to rest or sleep;
A plurality of inlet pipes are installed in the water tank to flow seawater back into the water tank; and
It includes a drain unit that discharges seawater flowing into the water tank through the inlet pipe to the outside,
The bed is,
A frame having a rectangular border; A plastic PE net covering the upper part of the frame and having a hole size of 20 mm to 40 mm: an insect screen formed on the upper surface of the plastic PE net and having a hole size of 0.5 mm to 1.5 mm; A sand plate laminated on the upper surface of the insect screen; And a plurality of support pillars positioned at regular intervals between the bottom of the water tank and the frame to support the frame,
The sand plate is composed of a royal sand layer formed on the upper surface of the insect screen and a middle sand layer formed on the upper surface of the royal sand layer,
The lower part of the water tank is composed of a slope that slopes downward from both side walls to the middle part,
The inlet pipe is installed at regular intervals along the downward sloping surface, so that the inlet pipe installed close to the drain installed in the middle of the water tank is closer to the bed than the inlet pipe installed relatively far from the drain. It is characterized by an increased upper and lower gap.

The water tank has an open upper surface, is provided with (n-1) partitions inside, and n (n: integer) partitions can be formed.

The drain unit includes a drain pipe installed vertically in the center of each section of the water tank, forming an inner pipe with an open top, and extending outward from the inner pipe; And a guide hole is formed on the side to guide the seawater toward the inner tube, and may include an exterior formed lower than the height of the inner tube at a certain interval on the outside of the inner tube.

The present invention provides a comfortable environment for growth by installing a sand bed in a (rectangular) water tank. Additionally, since the tank can be easily moved and managed, eco-friendly aquaculture is possible in a clean aquaculture environment. In addition, mass production (double cropping) all year round is possible when the temperature is warm. In addition, the uniform inflow and backflow control of cultured seawater prevents sand from rotting, creating a clean living environment on the sand plate, and the installation of open and close water gates between tanks makes cleaning easy.
