The basic (natural) movement pattern and gear-induced behaviour of female edible crab Cancer pagurus L. were studied by means of a stationary positioning system. Nine crabs were tagged with ultrasonic transmitters and their positions were monitored approximately every third minute for 9–24 days. Because the crabs sometimes hid, the signals were often received improperly, resulting in inaccurate position fixes, and a computer program to distinguish between movement and inactivity was developed… 

Edible Crabs “Go West”: Migrations and Incubation Cycle of Cancer pagurus Revealed by Electronic Tags

From the release of 128 mature female edible crabs tagged with electronic data storage tags (DSTs), predominantly westward migration in the English Channel is demonstrated, demonstrating that previous reluctance to tag crabs with relatively high-cost DSTs for fear of loss following moulting is unfounded, and that D STs can generate precise information with regards life-history metrics that would be unachievable using other conventional means.

Fisheries biology of the edible crab (Cancer pagurus) in the Kattegat and the Skagerrak - implications for sustainable management

The observed migration pattern indicates advisable management options in Sweden for this commercially fished species: protection of areas with high proportion of egg-bearing females from fishing, especially in the Kattegat and local management only on a small spatial scale is not recommended.

New approaches to the behavioural ecology of decapod crustaceans using telemetry and electronic tags

Monitoring depth and temperature in the immediate habitat of the animals, using electronic data storage tags recovered by the fishery, allow for movement patterns to be modeled using supplementary information on the topography and hydrography of the study area.

Quantifying the activity and movement of perch in a temperate lake by integrating acoustic telemetry and a geographic information system

The horizontal movement patterns of perch (Perca fluviatilis L.) were studied by means of an automatic positioning system in a small Mediterranean temperate lake in northeastern Spain. Seven perch

Diurnal activity in a group of Gulf of Maine decapods

The patterns of diel activity of four large decapod species in the shallow subtidal of the Isles of Shoals, Gulf of Maine, U. S. A. were investigated suggested that such diurnal activity is not only unusual for the three crab species of this study, but for the whole genus Cancer as well.

Behavioural responses of shallow-water benthic marine scavengers to fish carrion: a preliminary study

Observations of the behavioural responses of near-shore marine scavengers to fish carrion were made at two depths and Gobies and juvenile whelks were the most numerous scavengers, but appeared to consume little biomass.

Contrasting anti-predation responses in the intertidal periwinkle Littorina sitkana: effects of chemical cue, body size and time of day

Some animals show multiple behavioral responses after detection of chemical cues indicating a predation threat. Individuals of the high intertidal periwinkle, Littorina sitkana, showed two

Diarrhoetic shellfish poisoning toxins in Cancer pagurus Linnaeus, 1758 (Brachyura, Cancridae) in Norwegian waters

During the summer of 2002 there were several episodes of human intoxication after consumption of brown crabs caught along the Norwegian south coast, where one of the well-known phycotoxins, the diarrhoetic shellfish poisoning (DSP) complex, routinely found in blue mussels was found.

Use of ultrasonic telemetry to determine the area of bait influence and trapping area of American lobster, Homarus americanus, traps

Using ultrasonic telemetry, the distance of attraction to a baited trap was measured and then this value, along with the mean daily home range for the same animals, was used to calculate the “trapping area” of an individual trap.

Elevated pCO2 Affects Feeding Behavior and Acute Physiological Response of the Brown Crab Cancer pagurus

Elevated pCO2 caused crab metabolic rate to increase at the expense of SDA, and a positive relationship between feeding/SDA and pH, but negative relationships between the length of foraging periods and pH are revealed.



Occurrence and population composition of the edible crab (Cancer pagurus) on rocky shores of an islet on the South Coast of Norway

Diurnal vertical movements of Cancer pagurus L. pagurus have been studied by skin-diving surveys on an exposed rocky islet on the Norwegian Skagerrak coast and showed that males were stationary, whereas females migrated over longer distances.

Activity, track and speed of movement of the crab Scylla serrata in an estuary

Ultrasonic transmitters were used to track the movements of the crab Scylla serrata (Forskal) over 24 h periods in the Kowie estuary, South Africa and laboratory experiments indicated that the transmitters did not affect duration of emergence, amount of movement or feeding.

Movements of Individual Members in a Population of the Shore Crab, Carcinus maenas L., in the Littoral Zone

The aim of the experiment was to discover a kind of zonation at low tide in which the upper levels of the shore are inhabited by crabs whose physiological constitution differs in some way from that of crabs which are confined to the lower levels.

Patterns of recolonisation and the importance of pit-digging by the crab Cancer pagurus in a subtidal sand habitat

The nature and level of disturbance to a benthic community caused by the pit-digging activities of the crab Cancer payurus were examined in a shallow sub-tidal sand habitat on the west coast of Scotland, suggesting that the community returned to its original state within 25 to 30 d.

Crab (Cancer pagurus) migrations in the English Channel

A tagging study of the growth and migrations of C. pagurus was part of a research project undertaken to provide advice on the effective management of the English Channel crab fishery, finding that large, mature, female crabs leave the eastern Channel and congregate in the autumn off south Devon, and those females making the more extensive movements were larger than those caught in the vicinity of the release positions.

Natural food, foregut clearance-rate and activity of the crab Scylla serrata

The natural diet, rate of foregut clearance and diurnal activity of the crab Scylla Serrata were determined, and it was concluded that S. serrata does not normally catch mobile forms such as fish and penaeid prawns.

Diel variation of intertidal foraging by Cancer productus L. in British Columbia

Size/sex differences in movement patterns appear to be an important feature of the life histories of some cancrid crabs.
