The implications of fin erosion and other injuries that are directly or indirectly caused by the hatchery environment have long been debated. Fin condition has been regarded as an indicator of welfare in fish farms, but until now there has been littl

Cormorant (Phalacrocorax carbo sinensis) population increases and the resulting predation, can lead to severe effects on fish stocks. In the Dalalven River in Sweden, it was observed that the number of trout and salmon returning to spawn decreased, w

During 1960–2002, the arrival times of all spawning male and female Atlantic salmon (Salmo salar L., 1758) and brown trout (Salmo trutta L., 1758) entering Dalälven River were recorded. To study the role of environmental variation in spawning migr

Previous studies have shown kin recognition abilities in salmonid fish. Some authors have suggested that the attraction of juvenile fish to siblings may indicate preference for shoaling with kin. The aim of the present study is to test the prerequisi

In recent years, Baltic Sea salmon Salmo solar have suffered high larval mortality (M74) which can be cured by thiamine treatment. Analyses of long term mortality records (1928-1998) from two salmon hatcheries suggest that before the 1970s M74 did no

During the period 1968–1991, certain morphological traits of Atlantic salmon Salmo salar and sea trout S. trutta have been recorded regularly at the hatchery at Alvkarleby, central Sweden. Total body length, weight (for females both before and afte
