[ ] the original morphology
1Chinese prawn, grow up and laterally compressed body. Female180-240mm male body length, body length 130-170mm, carapace thin, smooth, slightly transparent, head cuirass hard big, the central front extension growth and a pointed head, upper margin with7-9teeth, lower margin with3-4teeth on the lower sides, with1on the eye, with handle. Brow ridges extending into the stomach near the brow ridge spines; after only extends to the middle of the carapace. Carotid sulcus, hepatic groove fine and apparent, clear liver puncture, orbital antennal groove is wider, eye gastric ridge very obvious. The head has appendages5, first, second to become the 2to whip tentacles, the second pair of antennae, particularly long, antennal spine is obvious; the other3pairs of appendages, become1 on the jaw and 2 pairs of maxilla. Thoracic appendages8, before 3to become maxillipeds, are a part of the remaining mouthparts;5for foot, before 3on the foot end are pincer, to third for most grown up, after 2to end a claw. Female body clasper presents disc-shaped, located at fourth, fifth on the foot base, is a central longitudinal fissure, for the spermatheca, in front of a circular protrusion, a densely hairy surface. Abdominal section 7, to buckling, section 4-6central backside with longitudinal ridges; abdominal appendages6, first of females are endopod minima, male endopod deformation as the bell-shaped clasper. Sixth for the uropod, stout, and abdominal section seventh end very sharp tail section into the tail fan. Female sex gonad maturity are light blue, brown and blue pigment cell surface spread. The male is slightly brown, thorax and abdominal appendage micro was red, the uropod half blue and red folder.
2shrimp, in shape, color and size etc, are quite similar with Chinese prawn. But on the upper edge of the lower edge of the 4-67-8 teeth, tooth. On the side of the shallow ditch, backward more shallow, to the stomach tattoo disappears beneath the. Forehead after ridge extends to the head near the trailing edge on the breastplate,1-2 has a shallow concave. On the base of the slightly higher than the convex end, back, relatively fine, first antenna whip and carapace length is approximately equal to or slightly shorter. The male copulatory organs lobular, apex rounded, margin setose, the two sides to the ventral curl. Female body clasper disc, front top tubercles from small, spiny tail section, back with a central longitudinal groove, the two side edges of the rear half of a bristle. Female than male individual. Body greyish blue head, blue point.
3Dark Kat prawn, figure and Chinese shrimp is also similar, but on the upper edge of the lower edge of the 4-58-9 teeth, tooth, on the side of the shallow ditch, backward more shallow, backward more shallow, to the stomach and stabbed beneath the brow ridge extends to after disappearing, head cuirass near the trailing edge. On the base of the back side view is very high, triangular, end is fine, first antenna whip and carapace length is approximately equal to or slightly shorter. Female clasper front top tubercles from considerable.
4of Penaeus monodon, this species is one of the largest of the genus Penaeus shrimp, female body length 300-350mm. On the upper edge of the lower edge of the 2-46-8 teeth, tooth, on the base of speciality, end of coarse, eye gastric ridge is shorter, straight liver ridge, fifth foot without external. Body with brown and dark green and white horizontal stripes, but often with the environment, age and color difference resort limb shank outside were yellow.
[ ] habitat distribution
Ecological environment:1inhabits shallow sea sediment, at night often slowly swim in the sea in the submucosa, feed on benthic polychaetes, small crustaceans, software and other vertebrate animal larvae, diatoms and so fresh. Every year in March from Hainan to Bohai yellow shell bait and reproductive migration, winter returned to yellow Hainan department for wintering migration. The male shrimp in October between 10-11 month in sexual maturity, mating, female shrimp to second years April sexual maturity, each tail female shrimp spawning hundreds of thousands to about 1000000 grains, eggs and stored in a female body clasper spermatophore within semen also put up and fertilization, the day begins hatching, young shrimp grow rapidly.
2inhabits the depth of 25-40m within the sandy seabed, shrimp often clustered in near the mouth of the river or sea life. In May7-8 month gonadal maturation, shrimp have been consistent with the standard of goods, from December to January the following year for wintering period.
3inhabiting littoral water depth of 25m within the sandy seabed.
4inhabits muddy or sandy seabed, shrimp or cluster in the aquatic weed in omnivorous. Mature outward seawater around 100m deep sea migratory, breeding period before returning to shallow water. Female shrimp is large, average weight of 350-400g, big up to500g.
Resource distribution:1China is mainly distributed in the Yellow Sea, Bohai and the northern East China Sea, the South China Sea are a small. A northern has a large number of artificial breeding.
2China's distribution in the Zhejiang Zhoushan the East China Sea, the South China Sea to the south coast of. Now the south of artificial breeding of the main varieties.
The 3China distributed in Guangdong, Fujian and other coastal. Have to undertake breed aquatics artificially.
The 4China located in Zhejiang, Fujian, Taiwan, Guangdong, Guangxi coast, is Taiwan's main cultured species.
