Riverfly Partnership Coronavirus (COVID-19) update

Dear Anglers’ Riverfly Monitoring Initiative (ARMI or Riverfly) participants,

We sincerely hope that all of you are keeping safe and well.

In light of the Coronavirus (COVID-19) pandemic, it is imperative that all ARMI participants continue to follow the latest regional and national advice regarding permitted activities, restricted activities, self-isolation, social distancing, and movement. If restrictions mean that you are not able to carry out ARMI activities, please refrain from doing so for as long as necessary. The safety and wellbeing of you, and of us all, are our priority. Please keep up to date with government advice which is changing frequently, you can do so by visiting https://www.gov.uk/ then clicking Coronavirus (COVID-19) links.     

This message can also be found on the homepage of the Riverfly Partnership website (https://www.riverflies.org).

We ask that all ARMI/Riverfly hub and group coordinators pass this message on to every group member, and please ensure that you and your group members are following the latest advice in your region. 

We will provide a further update if this guidance changes.

Best wishes,

The Riverfly Partnership

Resuming Monitoring **UPDATED August 26th**

A sampling net lies across a shallow river dappled with sunlight the words 'Riverfly and Safety' sit in a white box above the river

The following apples to England, Scotland, Wales and Northern Ireland.


You are now able to resume monitoring. This is at individuals own discretion, nobody should in any way feel obliged to recommence monitoring.


Before you recommence monitoring please;


  1. Check that your volunteer insurance provides cover for ARMI activity in relation to coronavirus. (If you are a registered volunteer through the host organisation of your Riverfly group or hub, you can check this with your local coordinator. If you participate in ARMI independently, i.e., you are not officially registered as a volunteer with the host organisation of a ARMI group or hub, you will need to contact your insurer directly.
  2. Contact landowner(s) and fishery manager(s) to request permission to recommence monitoring activity at the current time.
  3. Follow all current ARMI Health and Safety protocols. This should include regularly sanitising hands with an appropriate hand alcohol, not only in accordance with government guidance for coronavirus but also with regard to other contaminants, pollutants, and infections that may be encountered as a result of monitoring activity (especially through contact with river water) such as Weil’s Disease. Please note that the World Health Organisation (WHO) published ‘Water, sanitation, hygiene, and waste management for SARS-CoV-2, the virus that causes COVID-19 - Interim guidance’ on 29 July 2020 which states there is currently no evidence to support transmission in waste water. RNA can be detected but is non-transferable.


Observe the following additional protocols while sampling;


  • Maintain minimum 2 metres distance from others at all times
  • Carry a personal supply of appropriate hand alcohol and regularly to sanitise hands, especially immediately before and after using public transport, making contact with surfaces in the public domain (for example gates), making contact with monitoring equipment, and following contact with river water and anything else in the environment.
  • If you feel unwell please follow current government and NHS guidelines, and self isolate as appropriate.
  • Wash your hands thoroughly before going monitoring.
  • Consider wearing gloves and face mask / covering (always adhere to government guidance about mandatory wearing of face masks / coverings)


For updates and current guidance relating to coronavirus visit Gov.uk/coronavirus and NHS.uk/coronavirus 


We hope you are staying safe and well at this time. Riverfly monitoring can be a great way to connect with nature and enhance wellbeing. If you are able to do so safely, we sincerely hope you enjoy monitoring again
