Monitor and maintain the health and welfare of fish and aquatic animals in a Home Office designated establishment

URN: LANAnT17
Business Sectors (Suites): Animal Technology
Developed by: Lantra
Approved on: 2025

Overview

This standard covers monitoring and maintaining the health and welfare of fish and aquatic animals such as Xenopus in a Home Office designated establishment. Fish could include Zebra or other fish species.

When working with research animals recognise humanity’s obligation to them and your responsibility for ensuring their proper care and treatment at all times.

It includes monitoring and maintaining:
• Systems – primarily recirculating
• Water quality – monitoring and parameters
• Feeding regimes
• Breeding
• Larval rearing, including water quality and feeding regimes
• Juvenile grow-out programme

This standard is for animal technologists in Home Office designated establishments.

It is essential that you work strictly within the limits of the relevant project licence.

  11. take the required action if water quality falls outside of set parameters
  12. monitor and assess the health and welfare of the fish or aquatic animals, identify signs of ill health and take the required action in accordance with the organisation’s procedures
  13. confirm a correct feeding regime, depending on species and age
  14. prepare suitable diets for the fish or aquatic animals in your care
  15. set up breeding systems in accordance with the organisation’s procedures
  16. monitor and maintain a larval rearing programme in accordance with the organisation’s procedures
  17. monitor and maintain a juvenile grow-out programme in accordance with the organisation’s procedures
  18. keep accurate and up-to-date records as required by the relevant legislation and the organisation
  19. conduct all activities within the provisions of the project licence

Knowledge and Understanding

You need to know and understand:

  17. the basic signs of ill health in the fish or aquatic animals in your care and the possible causes
  18. the basic nutritional requirements of the fish or aquatic animals in your care
  19. why certain food types are fed at different stages of the life cycle
  20. the different ways in which fish or aquatic animals can be mated and the situations in which these may be used
  21. factors that can affect fish or aquatic animal mating
  22. the physiology of the different stages of the larval form to juvenile and how this affects the husbandry requirements at each stage
  23. the different physiological requirements of a juvenile compared to either a larval form or an adult and how this affects the husbandry requirements at each stage
