the Scientists of the research Center for aquaculture, which is part of the Alfred Wegener Institute Centre for polar and marine research Helmholtz (AWI) in Bremerhaven conducted an experiment that proved that the sea bass (Dicentrarchus labrax) European sea bass does not accumulate harmful plastic, in large quantities spread in the ocean.

They are specifically in a few weeks the fish were fed special food, which in addition to fish meal, wheat bran, vitamins and fish oil, was crushed microplastics, particles of which does not exceed five micrometers, according to the AWI website with a link to the publication in the journal Marine Pollution Bulletin. For the convenience of study these particles colored in yellow-orange color with fluorescing effect. For 16 weeks, every fish swallowed the order of 163 million micro-plastic particles – much more than I could really absorb in the ocean.

the researchers Then carefully examined portioned fillet of fish, dissolve the muscle tissue in solution of potassium hydroxide and passed through the filter, trapping any plastic particles. With the help of fluorescent microscope counting was conducted in random particles.

it turned Out that for every five grams of fillet had only one or two pieces of plastic.

the Scientists concluded that plastic is not absorbed by the body of seabass, noting in passing that itself fueled by the plastic the fish was in excellent condition and well developed.

head of the research group on aquaculture Dr. Slater stressed that the experience was only one kind of fish, and should continue to study the digestibility of the micro-plastic other types. Perhaps, anxiety about harm of consumption of fish from the ocean, littered with plastic, somewhat exaggerated, and fish fillets can still be safe for human consumption, even if eaten by fish subjected to extreme microplastic pollution.

In any case, such studies should continue to examine how the fish cope with inorganic food.
