Threat analysis
7
Barriers to migration – incl. damage by hydro. turbines (Winter et al. 2006, Acou et al. 2008, Azeroual
2010, van der Meer 2012)
Body condition (Boëtius and Boëtius 1980, Svedäng and Wickström 1997, van Ginneken and van den
Thillart 2000)
Climate change and/or changes in oceanic currents – including the influence of the North Atlantic
Oscillation (NAO) (Castonguay et al. 1994, Dekker 2004, Kim et al. 2004, Minegishi et al. 2005,
Bonhommeau et al. 2008, Miller et al. 2009, Durif et al. 2011, Pacariz et al. 2013)
Disease and parasites (Anguillicoloides crassus (Kuwahara, Niimi & Hagaki, 1974))
(De Charleroy et al 1990, Würtz and Taraschewski 2000, Vettier et al. 2003, van Ginneken et al. 2004,
Gollock et al. 2005, Palstra et al. 2007, Sjöberg et al. 2009, Haenen et al. 2012)
Exploitation and trade of glass, yellow and silver eels (ICES WGEEL 2012, 2013; Crook 2010; Crook and
Nakamura 2013)
Hydrology (e.g. Kettle et al. 2011)
Habitat loss (e.g. Feunteun 2002)
Pollutants (Robinet and Feunteun 2002, Maes et al. 2005, Palstra et al. 2006, Geeraerts and Belpaire 2010)
Predation (e.g. Carpentier et al. 2009, DEFRA 2010, Wahlberg et al. 2014)
