Shrimp Farming

Disease challenge by viruses, bacteria, fungi and toxic algae presents a major threat to profitable aquaculture production. Biosecurity, in other words reducing the number of infectious organisms in the aquaculture environment, is the most effective form of protection. Biosecurity is a set of management practices, which reduce the potential for the introduction, and spread of disease-causing organisms onto and between sites. Bio-security procedures, particularly disinfection and sanitation, should be combined with selection of pathogen-free seed and strategic treatments to either eradicate or reduce these pathogens to non-infectious levels. The Neospark Biosecurity Programme has been developed over many years with leading aquaculture producers around the nation. Neospark products and procedures have proven effective in practical farm conditions against a broad spectrum of pathogens. These include persistent and difficult to destroy immunosuppressive viruses causing WSSV,

Biosecurity is the management practices that prevent non-infected, healthy animal populations from being exposed to infectious or parasitic agents. Common biosecurity measures include: 1. Sanitation:                        Sanitation includes the cleaning and disinfecting of hatcheries, holding facilities, tanks, ponds, handling and vaccination equipment, etc. Cleaning must be done before disinfecting. Disinfectants include chlorine, heat, steam, formalin, and other chemical compounds. All of the chemical disinfectants are toxic, so all equipment should be rinsed well after disinfecting. 2. Vertical disease transmission:                        Vertically transmitted diseases (from parent to offspring) can be prevented by using healthy, disease-free broodstock. 3. Egg disinfection:                         Egg disinfection with iodine or other solutions at the time of the water hardening of eggs can reduce the incidence of disease problems of eggs and larvae. 4.

The world's demands for high quality aquaculture products make control of diseases increasingly important. Good Bio security measures are vital to maintaining healthy animals, to reducing the risk of acquiring diseases in aquaculture facilities and to harvest high quality good yield. Biosecurity Biosecurity can be defined as ‘the measures and methods adopted to secure a disease free environment in all phases of aquaculture practices (i.e. hatcheries, nurseries, growout farms) for improved profitability’. Biosecurity protocols are intended to maintain the "security" of a facility (i.e., prevent entry of, or reduce overall numbers prior to entry) with respect to certain diseasecausing organisms (parasites, bacteria, viruses and fungi) that may not be present in a particular system. In short, food producers have consumer safety as their primary target. If the food they produce is not safe, no economic model works. The second and equally important target

In order  L. Vannamei   can grow optimally, it needs a place to live that can provide state physics, chemistry, and biology is optimal. Physical environmental conditions are including temperature and salinity. While the chemical conditions is including pH, dissolved oxygen (DO), nitrate, orthophosphoric, and the presence of plankton as natural feed. Should be noted that environmental conditions can inhibit the growth of shrimp, shrimp can be deadly, such as the emergence of toxic gases and pathogenic microorganisms. Temperature is one factor controlling the speed of biochemical reactions.   This is because the temperature can determine the metabolic rate of shrimp and other aquatic organisms.   Low temperatures will result in a lower metabolic system in contrast to the high temperatures will spur a more rapid metabolism.   In order for the cultivation of L.   Vannamei to work well, pond waters temperature range suggested is between 28 - 32o C. Water transparency v

One of the inherent elements of characteristic aquatic ecosystems environments is the practically entire reusing of feed materials through the natural biological food web. Fish discharges are metabolized by microorganisms, reaped thus by planktonic creatures (potentially reused inside, e.g. algea control harvested gathered by zooplankton) and in the long run back to the fish. This element is still fundamental in broad culture lakes, however its part decreases as stocking thickness ( pond escalation ) is expanded. Organic loads The organic load in the more escalated pond is high, and an expansive portion of the organic matter settles onto the oxygen-restricted pond base, making anaerobic conditions, backing off the bio-reusing grouping and notwithstanding prompting to the generation of lethal mixes. What's more, the high feed load, stratification, and restricted oxygen supply will prompt to the restraint of nitrogenous waste digestion system, including the

Diseases of Shrimp Shrimp aquaculture is the most important marine aquaculture industry. In spite of the hazardous development in world creation of developed shrimp, there have likewise been stunning, intermittent misfortunes because of ailments. Subsequently, sicknesses are currently considered as one of the basic constraining elements in the shrimp culture. Genuine viral ailment episodes of shrimp test the shrimp business to be better arranged in the perspective of an expanded learning about shrimps and their pathogens so that ailment counteractive action techniques could be moved forward. This requires moved attention to biosecurity, that is, conceivable strategies for developing shrimp in limited frameworks intended to keep the section of potential pathogens. The business likewise understood that a decent number of ailment episodes started from reckless transboundary development of tainted yet terribly typical aquaculture stocks. Methods of Disease Control in Shrim

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
