The fish that did hatch in these waters with high quantities of micro-plastics were "smaller, slower, and more stupid" than those that hatched in clean waters, lead author Dr Oona Lonnstedt, from Uppsala University, said. When exposed to predators, about half the young perch from clean waters survived for 24 hours. Those that had been raised with the strongest plastic concentrations were all consumed by pike over the same period.Kind of a bad analogy! Teenagers eating fast food are getting too much to eat and getting fat. Fish eating micro-plastic are getting no nutrition at all and forgoing actual food. If there's any kind of decent analogy to be found, I'd like to know why they don't try to make some plastic concoction for us people to eat that we'll find more enticing and satisfying than food. Then we could lose weight.
Most surprising for the research team was the way that plastic changed food preferences. "They all had access to zooplankton and yet they decided to just eat plastic in that treatment. It seems to be a chemical or physical cue that the plastic has, that triggers a feeding response in fish," Dr Lonnstedt told BBC News. They are basically fooled into thinking it's a high-energy resource that they need to eat a lot of. I think of it as unhealthy fast food for teenagers, and they are just stuffing themselves."

"Young fish become hooked on eating plastic in the seas in the same way that teenagers prefer unhealthy fast food..."
