Shrimp Farming

Pond Preparation and Management Prior to a Pond can be supplied for another product, the extreme squanders, which collect in the pond amid the past harvest, must be evacuated and the dirt and water molded. Developing of shrimp in a disgracefully arranged lake may prompt to trouble in lake administration amid the way of life period, which could bring about a lessening underway limit of the lake. Pond Cleaning The cleaning of a Pond or evacuation of the squanders, particularly the natural and phosphatic squanders that have amassed in the lake base could be, expert by drying, liming and furrowing. In any case, these strategies could in any case leave an unfriendly impact on the water and soil quality in the lake, which could bring about a decline in the generation limit of the lake. There are two strategies for cleaning a lake as per the likelihood of the lake to be dried: Dry Method This strategy is utilized when the pond base can be dried tota

Application of Probiotics: Probiotic action is interceded by an assortment of impacts that are subject to the probiotic itself, the measurement utilised, treatment length and course, and recurrence of conveyance. A few probiotics apply their valuable impacts by expounding antibacterial atoms, for example, bacteriocins that straightforwardly repress other microbes or infections, effectively taking an interest in the battle against diseases, while others restrain bacterial development over the gut divider (translocation), improve the mucous obstruction work by expanding the generation of inborn insusceptible particles, or regulate the provocative/resistant reaction. A few studies have shown that example acknowledgment receptors (PRPs, for example, toll-like receptors (TLRs) flagging pathways, insusceptible reactions, and the emission of antimicrobial peptides, for example, defensins and chemokines by the epithelium assume essential parts in these instruments. Here are a few

Immune system: In relation to farmed shrimp, bacterial diseases are considered as the largest cause of mortality in larvae. The administration of a mixture of bacteria (Bacillus spp. and Vibrio spp.) positively influenced on survival and had protective effect against Vibrio harveyi and the white spot syndrome virus (WSSV).  This result was due to stimulation of the immune system, by increasing phagocytosis and antibacterial activity. The administration of a commercial probiotic for the larvae of Marsupenaeus japonicus resulted in increased survival (97%) being significantly higher than the control treatment. Thus, the use of Bacillus coagulans SC8168 as probiotic for postlarvae of Litopenaeus vannamei resulted in higher survival of animals . In a study with tiger shrimp (Penaeus monodon), the inoculation of Bacillus S11, a saprophyte strain, resulted in higher survival of post larvae challenged by a luminescent pathogenic bacterial culture. Bacillus su

1. White Spot Disease (WSD) Pathogen : White spot syndrome virus (WSSV) Species affected :   Penaeus monodon   and   Litopenaeus vannamei   (10-85 DOC) Mortality rate : average to high, 100% in some cases within 10 d. Clinical signs : lethargic or moribund shrimps aggregated at pond surface and edges, slow to erratic swimming behavior, overall body color often reddish, minute to large (0.5-2.0 mm diameter) white inclusions embedded in the cuticle; Control measures : early harvest, strict isolation of infected ponds from movement, strengthened control of transportation, disinfection of infected ponds using Calcium hypochlorite (chlorine). 2. Yellowhead Disease (YHD) Pathogen : Yellowhead virus (YHV) Species affected :   Litopenaeus vannamei Mortality rate : could reach 100% in 2-5 days after infection. Clinical signs : Affected shrimps showed sudden increase in feeding activity and abnormal growth, then loss of appetite; aggregat

Many factors must be considered when a farmer is deciding which species of shrimp he should culture. Due to its large size and high price,  Penaeus monodon  and  P. indicus  are generally considered for farming. It has also been seen that both these species are suitable for farming in Kerala's environment. Apart from these candidate species other commercially important species such as  Metapenaeus ensis ,  M. monoceros ,  M. brevicornis ,  Penaeus semisulcatus  and  P. merguiensis  are also potential species that can be grown in India. Another potential candidate species that is flooding international market is the White leg shrimp,  Penaeus vannamei. Although the Government of India has not yet given sanctions to culture it in the country, many Asian countries have already started to culture this species. Advantages of  P. monodon It attains a large size. Shrimp with a size of 10 to 12 pieces/kg are common, and sizes of 5 to 7 pieces/kg have been grown in pon

What is Biosecurity? Biosecurity is the process of taking precautions to minimize the risk of introduction and spread of infectious organisms into or between farmed animal populations. Why is Biosecurity so important? Biosecurity is very important to aquaculture because it prevents or limits the introduction and spread of disease within or between aquatic animal production facilities and sites. Since very few effective treatments are available for most aquatic animal diseases, effective biosecurity is the key to preventing these diseases. How are infectious organisms transmitted? Disease agents that infect aquatic animals are frequently spread between aquatic organisms in the environment, or equipment used to transfer animals from one holding unit or site to another. Some diseases can also be spread directly through the water by animals releasing the infectious agent or by sick animals dying. Known sources of aquatic animal infections include contaminated feed, equip

What is Biosecurity? Is a series of management practices to reduce the prevention of Infectious agents onto a shrimp farm.Essential aspect in food safety programs.Keeping food products wholesome in highest quality important for the health and benefits the consumers.Ensure consumer demand for the product. Profitability of Aquaculture enterprises. Shrimps are healthier and more productive, Benefits farming community profitability and better Environment. Role of Probiotics in shrimp farming ? Pro: favour, Bios: life. An antonym of antibiotic, probiotics involves in multiplying few good/useful microbes to compete with the harmful ones, thus suppressing their growth. A probiotic is a cultured product or live microbial feed supplement, which beneficially affects the host by improving its intestinal (microbial) balance. They are generally heterotrophic and feed on the organic digested sludge thus lowering the organic load of the pond ecosystem and improving the clarity of water. They p

Aquaculture : Aquaculture has been defined by the Japanese Resource Council, Science and Technology Agency as under: “Aquaculture is an industrial process of raising aquatic organisms upto final commercial production within properly partitioned aquatic areas, controlling the environmental factors and administering the life history of the organism positively and it has to be considered as an independent industry from the fisheries hitherto.” Objectives of  Aquaculture : Having defined aquaculture and mentioned some of the reasons which have contributed to imparting a fillip to aquaculture in recent times, it is proper to state the objectives of aquaculture. These are: Production of protein rich, nutritive, palatable and easily digestible human food benefiting the whole society through plentiful food supplies at low or reasonable cost. Providing new species and strengthening stocks of existing fish in natural and man-made water-bodies through artificial recruitment and tra
