"Plattfisken skrubbskäddan can be one of the reasons for its difficulties to recover, large stocks in the Baltic sea. It shows new research from the Swedish university of agricultural sciences, SLU, reports Vetenskapsradion."
"It seems now as if the amount of the flounder and the cod interact with each other. When it of 40 years ago, there were plenty of cod, it was short on the flounder, among other things, to large cod eat flounder."
"as to the cod stock has decreased, instead skrubbskäddan increased in number and in geographic distribution in the central Baltic sea, according to Vetenskapsradion."
"A greater amount of this flatfish may therefore disadvantage the cod, then they compete for the same food, mainly the demersal crustacean scab."
