Warm water occupancy by North Sea cod.
The North Sea has warmed in recent years and there is an ongoing debate into how this is affecting the distribution of fishes and other marine organisms. Of particular interest is the commercially important Atlantic cod (Gadus morhua L.), which has declined sharply in abundance in the North Sea over the past 20 years. Observations of the temperature experienced by 129 individual cod throughout ...
متن کاملVertical movements of North Sea cod
Various air-breathing marine vertebrates such as seals, turtles and seabirds show distinct patterns of diving behaviour. For fish, the distinction between different vertical behaviours is often less clear-cut, as there are no surface intervals to differentiate between dives. Using data from acoustic tags (n = 23) and archival depth recorders attached to cod Gadus morhua (n = 92) in the southern...
متن کاملOn the Non-Compliance in the North Sea Cod Stock
This paper estimates the economic value of the North Sea cod (Gadus morhua) stock under recent catch and several recovery scenarios. The research presents results on: a) what the value of catches and biomass would have been if the EU fishing fleet had followed the International Council for the Exploration of the Sea scientific recommendations (SRs) and Total Allowable Catches (TACs) in the 1986...
متن کاملCould Seals Prevent Cod Recovery in the Baltic Sea?
Fish populations are increasingly affected by multiple human and natural impacts including exploitation, eutrophication, habitat alteration and climate change. As a result many collapsed populations may have to recover in ecosystems whose structure and functioning differ from those in which they were formerly productive and supported sustainable fisheries. Here we investigate how a cod (Gadus m...
متن کاملSigns of cod recovery
While gloom surrounds the prospects of many global fisheries, one species seems to have benefited from a range of, often controversial, conservation measures. North Sea cod, once on the brink of collapse as a result of decades of overfishing, looked set for the same fate as cod on the Grand Banks off northeast America, but new evidence suggests numbers are now recovering. In a rare positive con...
