“…7), consistent with findings from earlier studies (Rasmussen & Giske 1994, Bjelland 1995, Goodson et al 1995. During this period, fish feed extensively on shallow distributed zooplankton during the crepuscular periods (Bjelland 1995, Rasmussen & Giske 1994), investing energy in gonad development and build-up of energy (lipid) reserves before the onset of the next winter period (Falk-Petersen et al 1986).…”

“…When feeding during the crepuscular periods, juveniles seemingly exploit the antipredation window by foraging at light levels which optimise the trade-off between feeding and minimising predation risk (Clark & Levy 1988, Rosland 1997. In winter and the beginning of spring, juveniles display midnight sinking behaviour after dusk (Giske et al 1990, Goodson et al 1995, distributing at deeper depths which may correspond with the temperature maximum (Giske et al 1990, Giske & Aksnes 1992. Adult fish carry out DVM during the productive season (March to September; Lopes 1979, Rasmussen & Giske 1994, Goodson et al 1995, but remain in deeper waters and suppress DVM in winter (Giske et al 1990, Baliño & Aksnes 1993, Goodson et al 1995.…”

We studied the temporal dynamics in the vertical distribution of Maurolicus muelleri scattering layers (SL) by examining continuous acoustic recordings over a 15 mo period in Masfjorden, Norway, complemented by intermittent sampling campaigns. The data revealed known patterns as normal diel vertical migration (DVM), midnight sinking between dusk and dawn, and periods without migrations, as well as novel behaviours consisting of early morning ascents, reverse diel vertical migrations, and interrupted ascents in the evening. During the first autumn of the study, adult fish modified their normal DVM behaviour by suspending their migration in the evening, yet ascending toward the surface in the later part of the night to reach upper layers during dawn. This behaviour was not observed during the second autumn of the study. By mid-to end of November (1st autumn), adult fish had suspended the nocturnal ascent entirely, and in the subsequent period until the end of January, a fraction of the population rather performed limited reverse migrations, slightly shifting their vertical distribution upwards during the first part of the day. From January to March 2008, fish interrupted their evening ascent at apparently random intervals and returned to deeper waters, instead of completing a full ascent to the surface. Our study underlines the value of long-term recordings, with the results suggesting that M. muelleri has the capability of changing its behaviour in response to ontogeny and internal state (satiation and hunger) as well as to external stimuli.

Eggers (1978) proposed that the adaptive value of vertical migrations was to minimise predation risk by avoiding predators. The predator avoidance hypothesis was later extended to include the optimisation of foraging in the anti-predation window at intermediate light intensities at dusk and dawn (Clark & Levy 1988, Scheuerell & Schindler 2003. The bioenergetic efficiency hypothesis states that organisms distribute at temperatures which maximise growth (Wurtsbaugh & Neverman 1988, Giske & Aksnes 1992, Bevelhimer & Adams 1993, while the foragingopportunity hypothesis predicts that the depth distribution of the predator overlaps with depth changes of its prey (Levy 1990a, Neilson & Perry 1990. On an individual level, the hunger-satiation hypothesis assumes that vertical movements of individuals are triggered by a change in their hunger or satiation state (Pearre 2003).Mueller's pearlside Maurolicus muelleri Gmelin 1789, a small mesopelagic fish (standard le...

Knowledge of the three-dimensional behavior and activity patterns of mesopelagic fishes is crucial for understanding their role in ecological and biogeochemical processes in the ocean. We here show that the use of submerged stationary echosounders enables detailed analysis of three-dimensional swimming behavior of small mesopelagic fishes in situ. We explore a 4-month continuous dataset containing more than 100,000 nocturnal tracks of juvenile Maurolicus muelleri, obtained from a surface-facing, moored echosounder in a Norwegian fjord. We extend previous observations of vertical nocturnal swimming and step-wise (stop-and-go) dusk and dawn migrations with the corresponding horizontal and turning behavior. In the middle of the night, the M. muelleri mainly drifted with the currents. Horizontal swimming speeds were then usually below 0.5 body length s À1 but increased substantially during the step-wise dusk and dawn vertical migration. Most vertical relocations were followed by a change in horizontal direction. Our observations are in line with hypotheses of growth maximization in the juvenile fish, and of reducing detection and encounters with predators.
