The Sound’s herring fishery collapsed around 1570, though the stock had not disappeared. Catches took nearly 400 years to reach comparable levels again.

The herring fishery that took 400 years to rebound—and what it teaches us today
From the 13th to the 16th century, herring from the Sound—the strait in the Baltic Sea between Denmark and Sweden—was one of northern Europe's most important trade goods.

A colorful, abstract digital image depicts two primate figures sitting on the branches of a tree. The top primate faces forward with yellow and peach skin tones and blue and green markings around its eyes. Below it, a second primate is shown in profile, rendered in dark blue and black hues with speckled points of light like the night sky. The tree consists of thick brown branches and leaves in shades of green and yellow, all depicted with a fragmented, mosaic-like texture.
