Recfishwest has announced the postponement of the annual Salmon Slam competition and Albany-based Salmon Spectacular events until 2021.
A Recfishwest spokesperson said the decision was a difficult one that the group hoped it would not have to make.
"We had hoped to be able to keep running the Salmon Slam as it is an app-based competition that lends itself to social distancing.
"However, the latest advice from Government has been very clear advising people to only venture out of their homes if completely necessary. On this basis we think postponing the Slam is the right thing to do."
More than 1000 people registered for the competition, submitting photos and catches to the mobile app to win prizes.
Recfishwest told sponsors and supporters in an email this week that given the WA Premier's directive to cease travel between regions, it would be unwise to promote an event that encouraged regional travel.
"Postponing this event is the responsible thing to do - we had planned to adapt the fishing competition to be run through our Salmon Slam 2020 app to allow people to still fish within the Government's social isolating guidelines.
"But in light of developments and current advice from Government - we decided it is better to throw our efforts into making sure next year's event is a fishing bonanza befitting of Albany and the Great Southern region.
"We're gutted that we've had to pull the plug, but we know you will understand it was the right thing to do and we will be back bigger and better with the comp next year."
As the annual salmon run continues to bring fish - and anglers - to South West beaches, Recfishwest is urging people to follow government guidelines and stay at home as much as possible.
A series of COVID-19 crisis tips and advice for anglers has been provided on the Recfishwest website.
