Recfishwest’s citizen science project Reef Vision is giving the WA fishing community a glimpse of the fish they are vying for. But at the same time, they are also contributing to important science research.
With recent artificial reef installations off the WA coast, scientists have been monitoring the colonisation of them and any changes to the fish community.
Currently there approximately 30 active recreational fishers already providing data to Reef Vision, which are critical in making this program a success.
“The videos have revealed 34,000 different individual fish from 79 species, including sawsharks, Samson fish, snapper and mulloway as well as a few extra surprises such as turtles.”
Recfishwest Research Officer and artificial reef specialist James Florisson says the project is getting fishing communities engaged with science.
It’s also an extremely cost-effective way to gather large amounts of data over long time periods.
Volunteers throw a baited remote underwater video (BRUV) system out from their boat and record an hour of video footage over the artificial reefs while they are fishing.
The videos are then sent to Murdoch Uni and Recfishwest researchers for analysis.
BRUVs consist of a GoPro video camera attached to a weighted PVC frame with a baited arm and bait bag attached to a float on the surface by rope.
So far, Recfishwest has received over 400 hours of footage from 212 videos from just 40 volunteers.
The videos have revealed 34,000 different individual fish from 79 species, including sawsharks, Samson fish, snapper and mulloway as well as a few extra surprises such as turtles.
“Volunteers absolutely love it, and a lot watch the footage straight away and share on Facebook—it’s a form of fishing of its own!”
“And the data shows us how well the artificial reefs are tracking and what’s growing on and around them,” James says.
“Traditional methods would have been cost prohibitive, so to have the community monitoring the reefs and producing rigorous ecological data is fantastic.”
Due to its success, Reef Vision is being expanded statewide.
Two new artificial reefs were recently set near Mandurah and Rottnest Island with others approved for Exmouth, Esperance and Dampier in 2018 and 2019.
