Ancient fish bones reveal impact of global warming

Scientists studying ancient fish bones in Scandinavia have discovered that warm-water species like anchovies and black sea bream that once thrived in Danish waters during a prehistoric warm period are now returning. Some cold-water species, such as cod, were also abundant during this period, having benefited from a lower fishing effort.

Through the study of archaeological material, tax accounts, church registers and account books of monasteries, an international group of fisheries ecologists and fisheries/maritime historians have drawn a picture of marine life in the northern European seas (North Sea, Wadden Sea, Baltic Sea, and White Sea) as it looked in the past.

Their findings are presented in a special issue of Fisheries Research “History of Marine Animal Populations and their Exploitation in Northern Europe” Volume 87, Issues 2-3, Pages 101-262 (November 2007).
