Scientists have found that fish larvae feed on plastic.
The use of plastic slows the growth of fry and makes them more vulnerable to predators.
Fry fish get used to plastic Science Naked Scientists said that fish in the oceans, from early childhood accustomed to eat plastic waste similar to how children get used to eating unhealthy fast food. The results of the researchers were published in the journal Science.
High concentrations in sea water, particles of polystyrene causes for juvenile sea bass addictive to them that slows the growth of the fry and makes it more vulnerable to predators. The researchers conducted a series of experiments in which fed fry sea bass microparticles of plastic.
In the absence of such particles about 96% of the eggs successfully developed into fry. In water tanks with a high concentration of mikroplastika this figure was reduced to 81%. The fry that were born in the more turbid the water, were smaller, moved slowly and had the worst sense of direction in the environment.
When meeting with predators about 50% of fry raised in clear water to survive during the day. Fry reared in tanks with the highest concentration of microparticles during the same period, killing all. Plastic also changes the taste preferences of fry raised in the murky waters of the fry prefer to eat plastic particles even when they have the opportunity to eat the zooplankton.
Earlier it was reported that a student at the Icelandic Academy of arts Ari Jonsson proposed an environmentally safe alternative to plastic bottles and created the first prototype of the tank from recycled algae.
