Diel migrations between habitats containing different levels of food abundance is a common phenomenon among marine organisms, both vertebrate and invertebrate. We hypothesize that in many cases this behavior constitutes a response to diel changes in the relationship between potential feeding rates and predation risks in the different habitats. For planktivores that locate their prey by sight (such as juvenile sockeye salmon) and that in turn are subject to predators that use sight to locate…

DIEL VERTICAL MIGRATION BY JUVENILE SOCKEYE SALMON: EMPIRICAL EVIDENCE FOR THE ANTIPREDATION WINDOW
TLDR
Data support the hypothesis that changes in habitat use by juvenile sockeye salmon reflect a dynamic strategy to minimize the ratio of predation risk to foraging gain that changes dramatically over the course of diel cycles in pelagic ecosystems.
Hunt warm, rest cool: bioenergetic strategy underlying diel vertical migration of a benthic shark.
TLDR
These results provide the first clear evidence that are consistent with the hypothesis that a benthic marine-fish predator utilizes DVM as an energy conservation strategy that increases bioenergetic efficiency.
Diel vertical migration of adult burbot: a dynamic trade-off among feeding opportunity, predation avoidance, and bioenergetic gain
TLDR
The results, which showed elevated nightly activity and a seasonal size-structured depth distribution during DVMs, suggest these migrations likely provide a feeding opportunity “window” for this nocturnal predator, constrained by predation or cannibalism threat.
An optimal foraging and migration model for juvenile plaice
  • M. Burrows
  • Environmental Science
    Evolutionary Ecology
  • 2005
TLDR
A state-dependent model has been used to predict daily and tidal patterns of migration, feeding and inactivity in juvenile plaice in their intertidal and shallow subtidal nursery areas and Tidally related behaviour persists in the latter environment, not predicted by the model and may be a consequence of using endogenous rhythms to approach optimal behavioural patterns.
Zebra diel migrations reduce encounter risk with lions at night
TLDR
The effect of a predator-induced DM on the likelihood of encountering a predator is quantified and the effects of the DM on encounter risk are distinguished from those related to day/night changes in selection for vegetation types.
Light-induced migration behaviour ofDaphniamodified by food and predator kairomones
TLDR
This work studied downward swimming of D. galeataxhyalina in response to stepwise accelerations of relative increases in the intensity of light at several food and fish kairomone concentrations, and found two clones showed a particularly significant difference in migration behaviour.
Partial diel vertical migrations in pelagic fish.
TLDR
It is shown for the first time that DVMs of freshwater fish resemble patterns of partial migrations often found in seasonal environments, and indirect evidence that the balance between migrants and residents may primarily depend on the trade-off between feeding gains and metabolic and predation costs of migration is shown.
The thermoregulatory function of diel vertical migration for a juvenile fish, Cottus extensus
TLDR
Given the overwhelming importance of fast growth for juvenile fishes, a post-feeding thermotaxs that increases digestion may be a common phenomenon increasing growth, and affecting the distribution and bioenergetic relationships of fish.
An optimal foraging and migration model plaice
TLDR
A state-dependent model has been used to predict daily and tidal patterns of migration, feeding and inactivity in juvenile plaice in their intertidal and shallow subtidal nursery areas and Tidally related behaviour persists in the latter environment, not predicted by the model and may be a consequence of using endogenous rhythms to approach optimal behavioural patterns.
Diel vertical migration of freshwater fishes – proximate triggers, ultimate causes and research perspectives
TLDR
It is suggested that migrating populations should split into migrants and non-migrants for whom the balance between mortality risk and growth rate can differ, and there is increasing evidence for this type of partial DVM within populations.

Predation and the evolution of vertical migration in zooplankton
TLDR
Examination of nonmigratory and migratory populations of a copepod in alpine clear-water lakes in the Tatra Mountains of Poland supports the view that migratory behaviour in zooplankton is selected for as a means of evading fish predators.
Predator evasion as an explanation of diurnal vertical migration by zooplankton
TLDR
The hypothesis that predator avoidance is one of the most important factors in vertical migration of planktonic crustaceans is supported.
Vertical Migration of Zooplankton: A Game Between Predator and Prey
  • Y. Iwasa
  • Environmental Science
    The American Naturalist
  • 1982
TLDR
This diel migration is studied by analyzing a habitat selection game between predators and prey based on the predation hypothesis, i.e., in the daytime zooplankton avoid predators (fish) that hunt by sight at the cost of reduced grazing on phytoplankon.
Limnetic feeding behavior of juvenile sockeye salmon in Lake Washington and predator avoidance 1
TLDR
Seasonal variation indicates that sockeye feeding behavior is a short term optimization process involving foraging success and encounters with northern squawfish and a general hypothesis to explain the relative fitness of alternative behaviorial decisions is presented.

The use of a high frequency echo sounder and a midwater trawl in Babine Lake, British Columbia, in 1967 revealed a precise diel vertical movement of underyearling sockeye salmon. From early July to…

Feeding ecology and vertical migration of adult alewives (Alosa pseudoharengus) in Lake Michigan.
TLDR
An examination of stomach contents indicated that vertical migrations were mechanistically linked to feeding behavior, and total lengths of Mysis in alewife stomachs were significantly longer than total lengthsof Mysis captured in vertical plankton tows.

TLDR
It is concluded that a mechanism of behavioral thermoregulation has evolved which favorably balances daily metabolic expenditures in order to conserve energy when food is limited.

TLDR
Growth rates of Babine Lake underyearling sockeye salmon fed rations of zooplankton and gross growth efficiency, ranging from < 1 to 31%, was affected by temperature and ration in much the same way as growth.
