IMPORTANCE OF BIO SECURITY




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, equipment, untreated wastewater, contaminated source waters, and pests such as birds or rodents.

What can we do to reduce the risk of disease introduction or spread?
  • Enforce strict sanitary measures for personnel, suppliers and visitors:
  • Provide disinfected protective clothing
  • Provide hand and footwear disinfection stations at each entrance and exit
  • Routinely disinfect equipment and water with recommended disinfectants. Ensure that the disinfectant can be applied safely and poses no toxic risk to humans, aquatic animals or the environment.
  • Restrict vehicle, boat and equipment contact with culture and holding units.
  • Maintain a log book of all visitors coming in contact with your aquatic animals.
  • Plan the flow of personnel movement through the facility and require that personnel undertake disinfection procedures between holding units and/or buildings.
  • Contain and/or treat effluent and organic waste at origin and prohibit it from re-entering production areas. For open water facilities, dispose of organic waste on land at a site that has measures to prohibit escape of breakdown products into surrounding waters.
  • Use pest management protocols to keep out birds, vermin and/or predators.
  • Use signage at the facility to inform visitors and personnel that there are biosecurity requirements in place such as controlled access, footbaths, video surveillance, etc.
How do I keep the aquatic animals in my facility healthy?

  • Choose your facility/site location carefully with biosecurity in mind; considering, for example: hydrographical characteristics, accessibility for stock in - stock out movements, and health status of surrounding farmed or wild aquatic animals.
  • Choose a safe water source for land-based facilities, use a disinfection and/or filtration system(s).
  • Stock only with certified disease-free eggs and/or aquatic animals.
  • Schedule routine disease monitoring with a veterinarian and implement an aquatic animal health management plan.
  • Remove mortalities and moribund animals routinely. When disease is suspected, contact your veterinarian.
  • Use caution prior to moving aquatic animals between holding units or farms. Aquatic animals showing signs of disease should not be sold or transferred to other facilities.
  • Minimize handling wherever possible to reduce stress that can predispose aquatic animals to infectious diseases.

Importance Components of BioSecurity

Image
Biosecurity involves following strict management protocols to prevent specific pathogens from entering a system or reducing the numbers. A good understanding of pathogen reservoirs is important. Quarantine, sanitation and disinfection are all important components of biosecurity . Quarantine , defined as the isolation of an organism or group of organisms to prevent the introduction or spread of infectious disease, is a standard procedure that is extremely important in aquaculture. In practical terms, quarantine is a standard set of procedures that should be observed to prevent the introduction of pathogens or diseases into a population of fish, prawn and shrimp in aquaculture. The quarantine protocols should be strictly adhered and should follow as many of the following protocols as are practical: testing of a sample of shrimp, prawn and fish prior to bringing them onto the facility. all-in, all-out stocking procedures. isolation or separation from other populations for ...

An overview of L. vannamei shrimp aquaculture

Image
Litopenaeus vannamei   is the most commonly cultured shrimp in Latin America and Southeast Asia, representing over 90 % of total shrimp production. India with its 8,118 km of coastline and 1.24 million Ha of brackish water area is the second shrimp producer in the world, with Andhra Pradesh being India’s largest vannamei farming area. Andra Pradesh, situated on the southern coast of the country, has 974 km of coastline and 175,000 Ha of brackish water. Andhra Pradesh has gradually increased its share in total marine exports of the country, with the United States and Vietnam as the main export markets. Currently, the state’s  L. vannamei aquaculture  is facing different issues and challenges to achieve sustainability related to diseases outbreaks, lack of availability of quality seed, high feed costs, unauthorized farming, international price fluctuations, less demand in the domestic market, and others. If farmers implement Better Management Practices (BMP) and  b...

The importance of biosecurity and disinfection in aquaculture

Image
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 ...
