Types of freshwater shrimp farming
The 2640 species known in the world, belonging to 39 families, have a close relationship with crab, crab shrimp and lobster. The characteristics of shrimp are semi -transparent bright bodies, soft and flexible abdomen, connected to the fan -shaped tail. Auxiliary limbs have evolved to swim. There is a long antennae. Freshwater farming of shrimp includes freshwater shrimp breeding and sea shrimp fade. The breeding varieties of freshwater shrimp in my country are: Japanese marsh shrimp, Rochena shrimp, freshwater lobster.
Curaki shrimp is also commonly known as green shrimp. It belongs to the soft armor, full of eyes, marching Asian, long -arm shrimp, and marsh shrimp is mainly distributed in Japan and my country. Object. Except for the western plateau, it is widely distributed in the ponds and ditches of lakes and ditches across the country. It has the characteristics of eating and high -breeding high -breeding ability. The water temperature of green shrimp survive is 0 to 34 ° C, and the water temperature drops below 8 ° C to enter the wintering period. The spawning period starts from May to September, and it begins to reproduce when the water temperature is 18 to 20 ° C. After three to four months of careful cultivation, most individuals can be for the listing specifications of four to five centimeters. Jiangsu, Zhejiang, and Shanghai are the main concentrations of green shrimp breeding and consumption.
The origin of Rochenna Shrimp is the Pacific Ocean of India. Roche Shrimp will have different habits with different growth stages. The development of the larvae must survive in the salty and fresh water at 8 ‰ -22 ‰. Prawn and adult shrimp live in fresh water. The living temperature is 15 to 35 ° C, and the growth temperature is 22 to 32 ° C. Succhers can live in fresh water in fresh water, and can also live in low saline water. And like to live in the downstream of the tide and the lakes, canals, paddy fields and other waters that are connected to the tide. The pond is cultivated for about five months, with a length of eight to nine centimeters, and weighing twenty to 25 grams. Park shrimp and shrimp are mostly lived alone, and they are mostly distributed on the edge of the waters. They are attached to water plants, branches, etc., and sometimes in the water activity.
The varieties of freshwater lobster in my country are red crab shrimp, Yabi shrimp and Kesharachi crab shrimp; The iPad mobile hard disk took Baidu schoolbag
The C4, crab shrimp native to the region of Central, South America and Mexico. In the 1930s of the last century, my country was introduced from Japan, and it has now expanded to Anhui, Shanghai, Jiangsu, Hong Kong, Taiwan and other places, forming a large number of natural population. Cechlona -like shrimp looks like shrimp and the crust is hard. The adults are about 5.6-11.9cm, dark red, the shell part is nearly black, and there is a oblique stripe on the back of the abdomen. The shrimp body is uniform gray, sometimes black ripples. Crab, narrow. The middle part of the crustacean is not separated by the mesh gap, and the crustacean is obviously granular. It can grow in the salinity of 3 ‰ to 9 ‰; it can withstand the high temperature of 40 ° C and low temperature of -15 ° C. Strong breeding.
The red crab shrimp, also known as Australian lobster, freshwater lobster, crayfish. The original Australian wild category, Australia started artificial breeding in 1971. It looks exactly like lobster and is one of the excellent freshwater farming shrimp in the world. The shrimp can live in rivers, lakes, and ponds, dystrophy, crawling, and survival in half salt water. Homeriousness, feeding organic debris, aquatic plants, aquatic insects, small -sized base animals, fermented cow dung and artificial feed. The best water temperature is 22-32 ℃. Extreme water temperature 4 ℃ and 37 ℃. When the water quality worsens, you can climb away from the water body to save himself. The larger individuals in nature are 500 grams, and the seedlings can grow to 60-100 grams in the year, and the 280 grams of male shrimp can grow to 280 grams. But naturally breeding, in the north
