Effects of carbon sources on the culture of giant river prawn in biofloc system during nursery phase
Commonly known as freshwater king shrimp, Macrobrachium rosenbelgium is one of the most expensive freshwater farmed species. The species is widespread throughout the country's major river systems, with many estuaries providing potential breeding grounds. Until the last few decades, this species was traditionally cultivated using seed collection from natural river sources. However, in recent years, there has been an increase in the farming of king freshwater shrimp in aquaculture areas. H. 12,022 to 43,395 ha, number of established hatcheries and incidence of white spot disease in tiger shrimp. Giant River prawns (Macrobrachium rosenbergii) fetch high prices on Asian fish markets. With aggressive marketing and the recent development of unisexual parent fish, it could soon become as popular as the vannamei shrimp. The giant river shrimp (Macrobrachium Rosenberg or GRP) is familiar to most aquaculture farmers. The discovery that their larvae required salt water to survive his five days or more is a legend in aquaculture. However, most international seafood consumers are decapod, meaning "big arm", which includes crabs, prawns, prawns, lobsters, crayfish, and other familiar creatures named after them. We don't know much about the largest member of the genus Macrobrachium. Consumers crave. About 240 Macrobrachium species are distributed in the tropics and subtropics and inhabit numerous rivers, ponds, lakes and streams on all continents except Europe and Antarctica. Most species are amphibians and require both fresh and saltwater to complete their life cycle. The eggs are washed out into the ocean downstream and then hatch to hatch and crawl up to 100 km upstream to repeat the breeding and cycle. Giant freshwater shrimp are suitable for farming in tropical and subtropical climates. The most commonly cultivated species in India is Macrobrachium rosenbergii. Due to its ability to adapt to a wide variety of fresh and brackish water conditions, it is a hardy species, accepting pelleted food and having an omnivorous feeding habit. Breeding takes place in low-saline waters and is also required for post-incubation larvae and post-larval development. Breeding of M. rosenbergii takes place in estuaries. Although the amount of seed available from nature is limited, large-scale cultivation requires ensuring a regular seed supply. Freshwater shrimp hatcheries where the technology is already developed should be encouraged to ensure the availability of high quality seeds in predictable quantities. Freshwater shrimp hatcheries are popping up in many states. Aquaculture production of the giant freshwater shrimp Macrobrachium rosenbelgii in India has shown tremendous growth in recent years, rising from less than 500 tons of him in 1997 to more than 30,000 tons of him in 2003. The biggest bottleneck to further expansion of shrimp farming is the insufficient supply of free-range juvenile shrimp (shrimp seeds). The projected seed requirement to develop at least 200,000 hectares of water over the next few years is 10,000 million. Aquaculture in India has evolved from subsistence level to industrial level. This transformation has been made possible by the development and standardization of many new production and related input/output subsystem technologies. In recent years, aquaculture has gained a lot of enthusiasm and interest among entrepreneurs, especially shrimp farming in coastal areas. Shrimp farming is a capital intensive activity and has been attributed to environmental problems where uncontrolled fungal growth leads to disease outbreaks and necessitates closure of shrimp farms.
