The clinic at Shelley foreshore promoted the �fish today for tomorrow� message, encouraging everyone to fish in a sustainable manner.
The year 5 and 6 students learnt about basic fishing skills, how to use equipment and correct fish-handling techniques, as well as conservation and fishing safety.
Recfishwest community engagement officer Bronte Nardi said the River Rangers also learnt about the Department of Fisheries� rules and regulations, including bag and size limits and closed seasons.
�The River Rangers program aims to empower students to make positive change to their local communities and waterways and ultimately the Swan and Canning Riverpark,� Ms Nardi said.
�Students get involved in the protection of the rivers by taking part in activities like tree-planting, litter pick-ups, building boxes for birds and bats, canoeing and sailing, team-building, dolphin watching, responsible fishing, water quality testing and learning about indigenous history.�
Ms Nardi said there were plenty of fish in the river.
�There are flathead in the lower reaches of the river, mulloway in the middle and bream in the upper reaches,� she said.
