Tide gates, used to regulate tidal flow as part of land reclamation programmes, temporally block fish movement by closing during the flood tide. Their impact on the upstream movement of brown trout, Salmo trutta, and other fish species has received l

Summary After a century of near absence, records of European catfish (Silurus glanis, L., 1758) in the Netherlands have increased markedly since 1994. The majority of records (about 60% of the total) originate from a 12 km dammed section of the River

There has been a decline in the abundance of Atlantic salmon (Salmo salar) despite significant conservation measures designed to reduce fishing mortality. Populations at the southern edge of their historical distribution, where anthropogenic impacts

A variety of proximate environmental triggers including water temperature and river flow have been correlated with the intensity and timing of salmon smolt migrations. In this study, the migratory timing and behaviour of wild salmon smolts leaving th

The migratory timing and behaviour of wild Atlantic salmon smolts leaving their natal stream was determined using a passive integrated transponder (PIT) antennae system at a study site on a tributary of the River Itchen, England. Experiments compared

In terms of the spawning migration of adult salmon, Salmo salar L., water flow is often considered the primary factor controlling river entry and fluctuations in flow controlling when the fish subsequently migrate upstream. However, water temperature

Advances in the field of telemetry techniques during the last few decades have greatly expanded our knowledge on migratory behaviour and provided the opportunity to obtain practically useful data for the conservation and management of salmonid popula

The seizure by Somali pirates of the Saudi-owned VLCC, the Sirius Star, with its crew, in November 2008, captured international attention. Across the world, regular updates were given and the ransom demands discussed and debated in the press. Dramati

Adult salmonids returning to the River Tees (north-east England) tagged with temperature-sensing acoustic transmitters provided some unexpected and novel information on the possible impact of seal predation at a tidal barrage 16 km from the sea. Pred
