Killer shrimp INVASION: Why Europe’s rivers are at risk from tiny ‘voracious PREDATOR’
The study saw one of three different Gammarus species, commonly found in European rivers, placed inside a tank.
In half of the tanks, a sample of the invasive “killer shrimp” was also present in small cages.
The Gammarus’ behaviour were then assessed, with researchers measuring whether the shrimp shredded leaves to the normal extent.
The results showed after four days each Gammarus species showed lower shredding efficiency in the presence of the killer shrimp, compared to the treatments where it was absent.
