Starving Seals Indicate Swedish Overfishing, Fuel Fears of Ecosystem 'Collapse'
Years of overfishing, and destructive practices by fisheries have put Baltic Sea staples such as cod and herring at risk of extinction, endangering the future and conservation of all sorts of other marine species.
Researchers in Sweden are ringing alarm bells about the threats overfishing pose to both humans and other species.
The herring shortage in the Bothnian Sea (which forms the northern part of the Baltic Sea) has driven seals to the point of starvation.
“They only have a thin blubber layer and risk dying - freezing to death,” fisheries consultant Kalle Gullberg of the Gävleborg County administrative board told national broadcaster SVT.
According to recent observations, the blubber layer in local seals is only a centimeter - and sometimes even less - rather than the five centimeters to be found in a healthy animal.
Lena Bergström, a professor of the University of Agriculture (SLU) confirmed that seals are suffering from a lack of food.
Seals are usually considered a major problem for commercial fishing as they feast on catches and destroy gear. Now the tables have turned and they are the ones suffering at the hand of humans. At the same time, the starvation of a top predator in the food chain indicates that the entire ecosystem has been disrupted and is at risk of falling apart. This dismal view has been analyzed by the Gävleborg County administrative board, which warned of the possibility of “collapse”.
“This is a big blow to other fish species as well,” Gullberg told SVT.
