Fish farming- paper 2

• Define the term fish farming.


  Fish farming is the practice of raising large numbers of fish in confined freshwater or seawater enclosures for commercial purposes, primarily to provide food for human consumption.
• What are some advantages of fish farming compared to wild-caught fish?

  Fish farming offers several advantages over wild-caught fish, such as:

  • The ability to selectively breed fish for quality and fast growth.
  • Protection against predators.
  • Control over water quality to reduce pollutants like mercury.
  • The ability to regulate feeding for rapid growth.
• What are some methods used in fish farms to ensure high yields?

  Fish farms employ various methods to ensure high yields including: 

  • Controlling and maintaining water quality.
  • Managing intraspecific and interspecific predation.
  • Preventing disease outbreaks.
  • Removing waste products.
  • Regulating the quality and frequency of feeding.
  • Selective breeding techniques are utilised to produce fish with desirable traits.
• Why is fish farming considered a sustainable alternative to wild-caught fish?

  Fish farming is regarded as a sustainable alternative to wild-caught fish due to its ability to produce large quantities of fish in a controlled environment, reducing pressure on wild fish populations. 

  Fish farms can ensure consistent production while mitigating environmental impacts such as overfishing and habitat destruction associated with traditional fishing methods.
• fish farming: controlling environmental factors 


  Fish farming provides the advantage of controlling various environmental factors such as water quality, feeding, and breeding conditions within the facility, allowing for optimal growth and health of farmed fish.
• How does fish farming help address the issue of overfishing?


  Fish farming helps address overfishing by providing an alternative source of fish protein that reduces the need for wild-caught fish. By raising fish in controlled environments, fish farms alleviate pressure on depleted wild fish populations, allowing them to recover and maintain ecological balance.
• How does fish farming contribute to water quality management?


  Fish farming contributes to water quality management by implementing measures to control and maintain optimal conditions within facilities. This includes monitoring and regulating factors such as oxygen levels, pH, temperature, and nutrient concentrations to create a healthy environment for fish growth.
• What steps are involved in fish farming to prevent disease outbreaks?


  Disease prevention in fish farming involves implementing strategies to minimise the risk of pathogens and infections among farmed fish. This includes strict biosecurity measures,regular health monitoring, vaccination programmes, and quarantine protocols to prevent the introduction and spread of diseases within aquaculture facilities.
• How does fish farming aid in waste management?


  Fish farming facilitates waste management by controlling and removing waste products generated by farmed fish, such as uneaten feed, faeces, and metabolic by-products. Techniques such as filtration systems help minimise environmental pollution and maintain water quality in facilities.
