特徴

産地:Subtropical, warm-water species in the tropics. Distributed in the southern Yellow Sea and Northern East China Sea of China. Also distributed in Pakistan, India, Singapore, Malaysia and other countries. They are mainly captured by shrimp boats around Zhoushan coast. The fishing season in East China Sea is from May to August, and from October to November in the Bohai Sean and the Yellow Sea.
Trachysalambria curvirostris (formerly Trachypenaeus curvirostris) is a species of prawn that lives in shallow waters of the Indo-West Pacific. It is one of the most important species targeted by prawn fishery, with annual harvests of more than 300,000 t, mostly landed in China.
T. curvirostris is widely distributed across the Indo-West Pacific, from East Africa and the Red Sea to Japan and Australia. It has also entered the Mediterranean Sea as a Lessepsian migrant, through the Suez Canal. It lives at depths of 10–300 metres (33–984 ft) over sandy or muddy bottoms.
特徴:It possesses rich nutrition like protein and many mineral elements such as potassium, iodine, magnesium, vitamin A, and aminophylline. Its soft and easy to be digested. It is the best food for those who are weak or ill. It is particularly useful for children and pregnant women.
Trachysalambria curvirostris is a small prawn, with males reaching a total length of up to 81 millimetres, and females reaching 105 mm. The exoskeleton is "densely pubescent" (covered in thick down). The rostrum is straight or slightly curved upwards, and bears 7–11 teeth on the dorsal (upper) side. The last four segments of the pleon have a median crest, while the second segment has a tubercle on the mid-line.
T. curvirostris can be distinguished from similar species that occur in the same areas (such as Megokris sedili and Megokris granulosus) by the form of the petasma and thelycum (male and female reproductive structures), and by the colouration of the uropods; these are red or reddish brown, with conspicuous white margins in T. curvirostris, but yellowish with grey or brown margins and centre in M. sedili, and red or reddish brown with golden margins in M. granulosus.
