Fish Screens

Intakes for irrigation and stock water systems are habitats for a wide variety of fish. So naturally, local authorities, Irrigation New Zealand, the Department of Conservation, and Fish and Game New Zealand, are all very proactive in protecting and managing this valuable natural resource.

Different rivers require different fish screens, so it's important to take into consideration the fish inhabitants in the river and their life cycle, to ensure that the correct fish management and best farm practises initiatives are used.

Combining the ever growing need to implement effective fish screening for both regulatory and compliance requirements, with the increasing need to have access to commercially used water (due to the increased demand from the shifting farming codes and the transition to farming practices in the rural area), bespoke fish screens on water intakes are becoming the accepted standard.

Hampton Engineering understands a number of critical areas and key elements that need to be addressed in order to have effective and code compliant designed fish screening systems. These factors include:

  • Fish species to be screened
  • Size range of the fish species and likely life stages to be screened
  • Movement of fish in the water column  
  • Fish swimming ability
  • Water velocity at the screen
  • Maximum allowable exposure time over the screen
  • Maximum screening material opening size
  • Effective escape route
  • Efficiency of screening
