In order to improve the utilization rate of the pond, the main cultivated shrimp model also derived double-season shrimp, fish and shrimp combined with one-season culture of shrimp, or one-year-old fish breeding, greatly improving the economic efficiency of the pond. Now the main modes of shrimp culture are described as follows: 1. Green shrimp double-season breeding mode. In spring January, every 667 m2 will be bred with 5 kg of autumnal shrimp species, and by the end of June, dry grasses will produce 15-20 kg of shrimp per 667 m2. From the end of July to the end of August in autumn, every 667m2 stocking 1.5-2cm shrimp 20,000 in the year, mixed with a small amount of summer flowers, by the end of every 667m2 production of fresh shrimp 30-50kg. 2, a quarter of Macrobrachium prawn breeding mode. In the middle and early May of May, 2-25 thousand tailed broodstock (L. rosenbergii) or 1.5-.25 million (2-3 cm) early-onset seedlings (Zhongrong Miao) or early October (or early October) were released. Conventional seedlings were arrested and listed. 3, raise fish into the spring, autumn culture shrimp mode. For every 667m2 of spring, from January to June, about 300kg of fish will be cultivated, which will be listed in the off-season for higher profits. In July, it will raise one season of fresh shrimp and 667 m2 of fresh shrimp will produce 30-50kg. 4. Three-year breeding mode. In April-May, silver bream was raised; in June-July, young shrimp were bred; in July-December, raised-quarter prawn was raised. 5, a breeding mode for the whole year. In January, each 667m2 stocking size is 2,000kg/kg, and 5-10kg in autumn and prawn species. The polyculture specifications are 25g/tailed bream and 220 species of bream. In May and June, shrimps were listed in stages and some of them were allowed to breed their own shrimp in the pond for the seeds of autumn shrimp. 6, fish-based mixed culture of shrimp mode. The use of fish as the main breeding medium for shrimp rearing usually results in mixed culture of appropriate amount of green shrimp on the premise of not affecting fish production and increasing the amount of feed. Make full use of the residual bait in the fish pond to achieve the goal of increasing the yield of the shrimp and improving the economic efficiency of the fish pond. General production of 400kg of fish ponds per 667m2, can produce 15kg of shrimp, per 667m2300kg of fish ponds, can increase more than 25 kg of shrimp. 7, grass, squid-based mode of polyculture of shrimp. Each 667m2 size is 350 to 160/kg seedlings per kilogram. Carp, each 667m2 size is 50/16-20 fry per kilogram; grass carp, 100/100 fry per kilogram. 10 to 13cm fish fry, 300 to silver seedlings, 200 to 30/60 fry per kilogram, and 2000 to 3000/kg shrimp per mu. Million. 8. The polyculture model of adult fish ponds, which is mainly made of silver cocoons. The standard of silver carp is to put 700 acre per kilogram of 25-70 tail fish fry, or raise silver pupae and summer flowers, put 1000 pounds of acre to cultivate next year's fingerlings, and black peonies to put 250 seedlings of fish whose size is 10-15cm; grass carp The acre has a size of 2-4 fish fry per kilogram, 100 fish fry a size of 10-13 cm, and the shrimp acre has a specification of 2000-3000 shrimps per kilogram of 1-2 million fish. 9, when the summer flowers cultivated fish pond polyculture. The silver mulberry acre has a specification of 800 fish fry 800 per kilogram, the carp acre has a size of 5cm fry 300 fish; the grass and carp acre puts 1000 summer flowers; the green prawn acre puts a specification 2000-3000 shrimp larvae per kilogram 1- 20,000. 10. The polyculture model of fish ponds based on grasses and catfishes. Squid, acres of summer fish species 3000 acres, grass carp, acres of summer fish species 2000 acres; carp acres of summer fish species of 1000 tail; species of shrimp, acres of 1-1.5 million. 11. The polyculture model is based on silver oysters. Ninety-nine mussels are placed in summer, 3000 mussels are reared, 1200 mussels are placed in mussel mussels, 300 balsams are placed in mussel mussels, and 2–30,000 mu are placed in mussels.
Rapid Application Tourniquet – A solid vulcanized rubber core with a nylon sheath combined with a unique locking mechanism make this a simple and incredibly fast tourniquet to apply to self or others.
Great product. Easy to use especially for people not used to applying Tourniquets. Fast to put on and fast to secure with the built-in cleat. Small enough to fit just about anywhere. Even in you pocket.
How to use the tourniquet?
The tourniquet has a metal cleat at one end and a long, elastic band made of vulcanized rubber attached to it.
Start by holding the metal cleat in one hand.
At the end with the cleat, the rubber band should be threaded through to form what they refer to as a three finger loop . Your limb does NOT go through the three finger loop.
Place the cleat on the limb requiring a tourniquet and wrap the long length of rubber around the limb.
Thread the long end of the rubber band through the three finger loop and pull until snug.
Wrap the long length of rubber back on itself and continue wrapping the limb until the elastic is used up or the blood flow has stopped. With every wrap you should be stretching the rubber so that the band pulls tight and cuts off blood flow. Do not pull the band as tight as it can go because it can cause permanent neurovascular damage if tightened too much.
Hook the end of the rubber band into the cleat to secure the tourniquet in place.
The tourniquet hallmark is use under stress.
