Immigration and emigration of cod in the spawning areas of Lofoten and Møre [PDF]
Abundance estimates of the spawning stock of north east Arctic cod have in recent years been given on the basis of acoustic surveys. Migration in and out of the surveyed areas during investigation has been considered as a possibly major source of error in the estimates. By studying the migration of tagged cod in the spawning grounds of Lofoten and Møre

Earthquake‐Spawning Faults in the Seoul Metropolitan Area and Their Seismic Implications [PDF]
AbstractQuaternary faults run across the Seoul metropolitan area that is the highest population region in the Korean Peninsula. Active fault identification and seismic hazard potential assessment are crucial for public safety. Densely deployed permanent and temporal seismic stations enabled us to detect micro to small earthquakes, allowing us to ...

Migration route and spawning area fidelity by North Sea plaice [PDF]
Data from plaice, Pleuronectes platessa L., tagged with electronic data storage tags, were used to test whether these fishes exhibited migration route and spawning area fidelity in successive spawning seasons. Depth and temperature data were recorded for each fish over 365-512 days in the central North Sea and this information was used to reconstruct ...

EC request on Blue ling protection areas during spawning period
ICES advises that information on the proportions of spawning blue ling (defined as running males and females, including females with hyaline eggs) and of non-spawning blue ling (all other maturities) at length are recorded at the individual haul level ...

Many species that provide productive marine fisheries form spawning aggregations. Aggregations are predictable both in time and space and constitute nearly all of the reproductive activity for these species.

A study of surface currents in the spawning area of Brazilian sardine [PDF]
To obtain the movement of surface currents in the spawning area of Brazilian sardine, drift card release experiments were conducted in south Brazilian waters during the spawning seasons of 1969-1971. The results of these experiments and some considerations about the drift of sardine eggs and larvae are described.
