The genes show how we can avoid herring collapse

New results show that current herring management does not agree with how the various herring populations move. "This means that herring fished north of 62 degrees are not only NVG herring, but a mixture of different herring populations", says researcher Florian Berg. Different populations "We know that herring is a species, but there are several varieties of herring, different populations. These live a little differently from each other", says Berg. Some spawn in spring, some in autumn and some in winter. Different stocks have adapted to different environments, such as different salt content in the water or temperature differences. Each herring has its own unique genetic code, but within the same population there are some common genetic markers that repeat themselves in all the fish. "We tracked these common genetic markers, to understand where the different pop... FULL STORY
