A couple of boaters on the lookout for a barramundi down Western Australia’s Fitzroy River came across something entirely different when they ended up rescuing an endangered sawfish.Footage by Karen Rule of Positive Fishing shows her and her partner John “Johno” Marven heading towards the shore after spotting what they thought to be a dead fish entangled in a net.“We see something strange; it wasn’t right. We couldn’t get the tinny in close enough, the water was too shallow,” Marven told Storyful.The pair jumped into the ankle-deep water to take a closer look, only to find a very lively sawfish vainly trying to free itself. Video shows Rule holding the net as Marven proceeds to cut it and help the critter back into deeper water.Both smalltooth and largetooth sawfish feature on the NOAA Fisheries list of endangered species.Talking to the ABC, Rule said, “We pushed him back into the deep and he swam off safely. It was a very nice feeling … to see him glide off.” Credit: Positive Fishing via Storyful
