INTRODUCTION
Light is an environmental variable that together with
abiotic, e.g. temperature or oxygen, and biotic, e.g.
food abundance or predator density, factors deter-
mines which habitat marine organisms occupy in the
pelagic environment (McFarland 1986, de Robertis
2002, Metcalfe et al. 2008, Boscarino et al. 2009). Visu-
ally foraging fish require light to sustain feeding
(Eggers 1978, Aksnes & Utne 1997, Ryer & Olla 1999,
Boscarino et al. 2010), but the anti-predator behaviour
of many fish also appears to be affected by light
(Kaartvedt et al. 1998, Ryer & Olla 1998). Changes in
the vertical distribution of fish have thus been associ-
ated with concurrent changes in surface irradiance
(Roe 1983, Baliņo & Aksnes 1993, Rasmussen & Giske
