I studied the feeding behaviour of cod in late spring in a fjord in northern Norway by means of a stationary positioning system. The activity rhythm of eight cod tagged with acoustic transmitters was observed continuously for 3-8 days in terms of swimming speed and size of area occupied. I studied responses to food odour by setting a line with mackerel baits in the experimental area. The cod had a diurnal rhythm of swimming activity with a slightly lower swimming speed during a 5-h period at… 
Activity patterns of juvenile Atlantic cod (Gadus morhua) in Buckley Cove, Newfoundland
We monitored swimming speed of 2–3 year-old juvenile Atlantic cod (Gadus morhua) from August to December 1999, using a 2-D location finding acoustic telemetry system in a coastal area of
Effects of turbidity on the spontaneous and prey-searching activity of juvenile Atlantic cod (Gadus morhua)

TLDR
Activity of juvenile cod was nonlinearly affected by turbidity and was lower at intermediate turbidity, regardless of the presence of prey odour, and both longer prey-search times and higher activity indicate that increased energetic costs are probable at high turbidity.
The dispersal patterns and behaviour of North Sea cod (Gadus morhua) studied using electronic data storage tags*
The migratory behaviour of adult cod was studied using electronic data storage tags (DSTs). Fifty-eight cod were externally tagged with LOTEK LTD-100 DSTs and released off Lowestoft in March and
Variable swimming speeds in individual Atlantic cod (Gadus morhua L.) determined by high-resolution acoustic tracking
Abstract Although several studies have determined swimming speeds for Atlantic cod (Gadus morhua L.) using acoustic telemetry, none have reported high-resolution tracking (high sampling frequency)
Daily activity pattern of the sand goby, Pomatoschistus minutus (Pisces), at low light intensity
TLDR
The activity of P. minutus in autumn is studied using video recordings in the laboratory, under light (1.5–2 lux) and temperature conditions prevailing at ca.
The Influence of the Circadian Rhythm of Green Frog (Rana clamitans) Tadpoles on Their Antipredator Behavior and the Strength of the Nonlethal Effects of Predators

TLDR
This work tested how the antipredator behavior of green frog (Rana clamitans) tadpoles can be influenced by their circadian rhythm and how the strengths of nonlethal effects vary in turn, and found Tadpoles exhibited stronger activity reductions when under predation risk during the day (which may result in stronger resource depression) but remained inactive during both day and night.
The life-cycle of sandeel - adaptations to a seasonal environment, from the perspective of a forage fish
TLDR
It is suggested that neglecting the importance of the overwintering phenomenon and seasonality in the environment may lead to failure in understanding population fluctuations of not only sandeel but possibly forage fish populations in seasonal environments in general.
Fine-scale activity, distribution and habitat utilization of Atlantic cod (Gadus morhua) on the Ipswich Bay spawning ground
Data storage tags (DSTs) and acoustic telemetry were applied to examine cod spawning habitat utilization in Ipswich Bay and compare seasonal activity patterns. I tagged 200 spawning cod in Ipswich
Zooplankton Hydrodynamics: An investigation into the physics of aquatic interactions
Zooplankton are hugely abundant organisms found in all aquatic environments and form an important part of the marine ecosystems. Most zooplankton swim in order to nd food and mates, and to avoid
Multi-torsking: simultaneous measurements of cod behaviour show differences between North Sea and Irish Sea stocks*
Fish behaviour can vary considerably in response to environmental and biological conditions. We used electronic Data Storage Tags (DSTs) to investigate the behaviour of cod in different environments;
