Baltic may become a dead sea
Year after year, the Baltic Sea has less and less to offer fishermen. The state of fish stocks is deteriorating at a rapid pace. Fishermen call for action to improve the situation, because if nothing is done, in a few years the Baltic may become a dead sea.
Last Thursday, a meeting took place between representatives of the Ministry of Maritime Affairs and Shipping and the Ministry of the Environmentodlądowa with the fishing community and scientists who study marine flora and fauna. The meeting discussed the increasingly poor condition of fish in the Baltic Sea – reports PortalMaritime.en.
Scientists whooThose who took part in the talks are aware of the dire state of fish in the Baltic Sea, particularlyolnie cod. However, unequivocally identifying the reasons for this situation is difficult.
Such action has probably disrupted the entire food chain. As PortalMaritime points out.en, according to a recent study by the Institute of Environmental Protection, far fewer compounds are flowing into the Baltic Seaoin nitrogen. This causes phytoplankton to disappear, which in turn leaves smaller fish without food. This raises problems roAlso with the food of larger fish.
– These are no longer fish, but floating bones from skorą. The fish is gone all along the coast. The worst, however, is in the bay, where the fish just completely disappeared. This is already the agony of the Baltic. If we do nothing, in a few years the Baltic will be a dead sea – mofishermen quoted by PortalMaritime.pl.
Fisherman’s wordsoin seem to confirm other data. Last year, Polish fishermen caught the only 57 percent of the. national limit on cod. It is not because of rare catches, but because cod is simply no longer present in such quantities as it used to be. Cod is dying out because there is nothing to eat.
Environmental physicist Dr. Przemysław Wachniew of the AGH University of Science and Technology also recently pointed out the problem of Baltic pollution. His teamoł has carried out an international research project Soils2Sea in recent years. AGH scientists analyzed the processes of transport of biogenic pollutants through soils and groundwater.
According to the study, the poor state of Polish wod and the Baltic Sea is not only the effect of current fertilization of landoby the farmerow. – Today we are struggling with the effect of fertilization used back in the 1970s, 1980s – pointed out last month in an interview with PAP, the scientist from the Academy of Gor of the AGH University of Science and Technology in Krakow. As he explained, groundwater carrying contaminants in many cases remains underground for quite a long time, and can flow into a nearby river after several decades.
Rivers are polluted most where there is the highest population density and most intensive agriculture. Fertilization and animal husbandry are the mainoin terms of contamination byodles pollution of rivers with nutrients (approx. 90 percent. on a national scale), but locally significant may be pollution from treated and untreated wastewateroin the livestock. And all this then flows into the Baltic.
Polish soils are quite permeable to water and pollutants, few harmful in excess fertilizer componentsoin them undergoes retention or decomposition. – Our results lead us to consider all of Poland a dangerous area, such a black spot on the map of Europe when it comes to pollution in theod – admitted Wachniew.
Correction: Professor Jan Marcin Węsławski of the Institute of Oceanology of the Polish Academy of Sciences did not point out the „restrictive policy of river treatment, whichore flowing into our sea, which makes the water flowing into the Baltic sterile and devoid of compoundsoin influencing the development ofoj life”. Minister Grzegorz Halubek’s statement was mistakenly presented as Professor Węsławski’s, for which we sincerely apologize.
