Stock collapse is more than a simple reduction in abundance
Over the last century, overfishing has led to the collapse of many fish stocks. Some of them, following successful management actions, have rebuilt their number but did they remain the same? In a recent study published in Ecology and Evolution we explored the effect of collapse on the stocks ecology by testing for differences before and after.
Analyzing newly digitized historic data reveal climate link in jellyfish abundance in the Norwegian and Barents Sea
Jellyfish are usually not targeted by scientific surveys that focus on commercial fish stocks. However, they are very often found in the by-catch of egg and larval surveys. In a recent paper in ICES journal of Marine Sciences , we studied such by-catch data from surveys conducted between 1959-1993 in the Barents Sea showing the high value of such historic data.
