The Rochester marsh shrimp lives in freshwater from the juvenile to adult shrimp stage, and the mature parental shrimp mates and holds eggs in freshwater, discharges its fry in brackish water, and the larvae develops in brackish water. is an omnivore, different stages of growth and development, mainly to aquatic insect larvae, small crustaceans, aquatic worms, other animal carcasses, and organic detritus young plant debris as food. It is mainly found in Bangladesh, Brunei Darussalam, Cambodia, China, India, Indonesia, Malaysia, Myanmar, Pakistan, Philippines, Singapore, Sri Lanka, and Thailand.
Rochester swamp shrimp breeding incubation and larval development needs to be in a certain salinity of brackish water , so the freshwater ponds in the rearing of rosella can not naturally reproduce, the culture of rosella shrimp required for the shrimp fry rely on artificial reproduction cultivation. Coastal shrimp nursery can be used to properly transform the breeding of Rochester shrimp seedlings, or the construction of specialized Rochester shrimp nursery breeding production.
Farming technologyRochester shrimp after cultivation, sexually mature shrimp in the appropriate environmental conditions (water temperature of 24 ~ 30 degrees Celsius), the beginning of natural spawning and fertilization, fertilized eggs hatch. flea-like larvae from the shrimp eggs out of the membrane, into the appropriate environment in order to develop normally, and finally metamorphosis into shrimp . When more than 90% of the larvae metamorphosis into young shrimp, that can be freshwater domestication (desalination). The same pool of shrimp fry before desalination, the pool of undeformed larvae fishing up, to other larvae of similar size in the cultivation of the pool to continue to cultivate. desalination, the first pool water level down , and then add fresh water at one end of the shallow, at the other end of the suction of fresh and salty water, to keep the amount of water in and out of the same, until the pool water into fresh water until the whole process of desalination, generally completed in 6 to 8 hours. After desalination of baby shrimp can be moved to the middle of the cultivation pool to cultivate, or directly into the pond culture.
The desalination out of the pool of Rochester shrimp seedlings, body length of 0.7 to 0.8 cm, tender, feeding and disease resistance are relatively weak , need to go through the shrimp seedling stage of cultivation, time of 1 month or so, to the juvenile shrimp body length of 3 to 5 cm, and then transfer to adult shrimp rearing! The shrimp are then transferred to the adult shrimp rearing stage. Can also be combined with the cultivation of young shrimp, the use of greenhouse or plastic greenhouse insulation cultivation of young shrimp, early release of shrimp seedlings, to be open pond water temperature is appropriate, can be divided into pond rearing, in order to advance the time of the listing of adult shrimp, to obtain a larger specification of the commercial shrimp, to enhance the competitiveness of the market.
