WWF listed the shrimp, found in the North Sea, as an endangered species in its annual fish guide for Swedish consumers.
But representatives of the fishing industry have urged Swedes to "keep fishing and eating shrimp".
Yngve Björkman, head of the Federation of Swedish Fish Industries and Trade, said Swedes do not need to feel guilty about eating shrimp as there is a healthy stock in the ocean.
However, the WWF claimed overfishing and dumping of small shrimps back into the sea has led to its scarcity.
Shrimps from the Skagerrak, the Cattegat, the North Sea and the whole of the Atlantic are now on the red list, published last week.
But there will still be shrimps in Swedish shops, Swedish Radio News reported, as a lot of the shrimps sold here are Norwegian from the Barents Sea, which according to the WWF is fished in a sustainable manner.
