Quick Summary

Senior researcher Chris Bice from South Australia's Research and Development Institute (SARDI) says that lampreys, a blood-sucking, eel-like fish, have not been seen for two consecutive monitoring periods in the Murray River. The disappearance could be due to a harmful algal bloom that affected over 20,000 square kilometers of South Australian waters in March 2025 and killed approximately 1 million marine animals. According to Bice, SARDI usually catches 20-100 lampreys during winter monitoring, but this year they have caught none. Scientists are concerned about the potential impact on the species' upstream migration and are hoping that they will re-emerge or recover next year.

Story summary

In South Australia, a researcher from the South Australian Research and Development Institute (SARDI) has expressed concern over the disappearance of lampreys, a blood-sucking, eel-like fish. Chris Bice, a senior researcher, said his team usually catches between 20 to 100 lampreys during their winter monitoring periods, but this year they have caught none despite trying hard. The absence of lampreys may be linked to a harmful algal bloom in the region, which has already caused significant damage to marine life. Scientists are worried that lampreys could be the latest casualty of the bloom, and hope that they will re-emerge or recover next year.

Senior researcher Chris Bice said the team usually caught about 20 to 100 lampreys, but the last two monitoring periods had left them empty-handed. "This year, unfortunately, we haven't caught any despite trying reasonably hard," he said.

The disappearance of a blood-sucking, eel-like fish could be welcome news for those who are fearful of the toothy creature, but scientists say they are concerned lampreys may be the latest casualty of South Australia's devastating algal bloom. uncertain
lampreys → suck → bloom
Every winter the South Australian Research and Development Institute (SARDI) uses fishway traps to monitor for lampreys as they swim from the ocean through the barrages into the Murray River. asserted

While the "incredibly cryptic" fish could be hard to catch, Dr Bice said he was concerned about what may have led to their absence. "On the weight of evidence, I think it's pretty fair to say that the algal bloom may have had an impact on the upstream migration of these fish,"he said. uncertain
bloom → catch → fish,"he
Beginning in March 2025, South Australia's harmful algal bloom stretched across more than 20,000 square kilometres and resulted in the death of approximately 1 million marine animals of more than 600 species, according to the Australian Marine Conservation Society. uncertain

The species can be traced back hundreds of millions of years and are related to "an ancient family known as the jawless fishes", according to Dr Bice. uncertain
species → trace → Bice
Estuarine ecologist Faith Coleman said while the algal bloom could be a contributing factor to the lack of sightings in the River Murray, there could be several reasons that SARDI was unable to catch them. uncertain
SARDI → say → them
"Most farmers will tell you there's been some really weird things around climate and that may have also changed how the lampreys migrate," she said. uncertain
she → tell → climate
Dr Coleman also said dead lampreys could have gone undetected due to their biological makeup. uncertain

"There is a question of whether they float when they die or whether they sink," she said. asserted

"We've found a lot of species have been badly impacted [by the algal bloom], but because of how their biology works, they have sunk rather than floated and they've not come into shore. asserted

Dr Bice said they only had a short window to research the relatively unknown species each year. asserted

"Right now we know almost nothing about the marine part of their life cycle." asserted

Despite their alarming appearance, Dr Bice assured people they had nothing to worry about if they were lucky enough to come across a lamprey. asserted
they → assure → lamprey
"When they're on their freshwater upstream migrations, they actually stop feeding," he said. "As soon as they enter freshwater, they're no danger to humans at all. asserted
they → stop → humans
