Preserving large females key to sustaining Atlantic cod
Cod was once a staple diet across many European countries, and so important in fact that in the past some countries have even gone to war over this important resource.
Their popularity, however, meant that they have become overfished in some areas leading to a shortage of large and old cod, which in turn has led to the fish becoming more sexually mature at a younger age.
This, according to research conducted by the University of Gothenburg, Sweden has led to a serious change in cod stocks and could severely impact the fish’s health, physiological ageing and reproductive capacity.
