Intertidal migration by the shore crab Carcinus maenas
Intertidal migration by the shore crab Carcinus maenas (L.) was studied on a seasonal and tidal basis from May to December 1992 on Ynys Faelog, Menai Strait, North Wales, UK. Work was carned outExpand

Quantifying physiological influences on otolith microchemistry
Summary Trace element concentrations in fish earstones (‘otoliths’) are widely used to discriminate spatially discrete populations or individuals of marine fish, based on a commonly held assumptionExpand

Migration route and spawning area fidelity by North Sea plaice
Data from plaice, Pleuronectes platessa L., tagged with electronic data storage tags, were used to test whether these fishes exhibited migration route and spawning area fidelity in successiveExpand

Migratory behaviour of the thornback ray, Raja clavata, in the southern North Sea
Although depleted throughout the European continental shelf, the relatively high density of thornback rays Raja clavata, in the Thames Estuary (UK) makes it an important stock centre and potentialExpand

Impacts of migratory behaviour on population structure in North Sea plaice
Summary 1. Migration is widespread among marine fishes, yet little is known about variation in the migration of individuals within localities, and the consequences for spatial population structure.Expand

Geolocation of free-ranging fish on the European continental shelf as determined from environmental variables
Demersal fish cannot readily be tracked using satellite-based or light-based geolocation techniques. As an alternative, we describe the tidal location method, which uses tidal data recorded byExpand

Geolocation of free-ranging fish on the European continental shelf as determined from environmental variables II. Reconstruction of plaice ground tracks
Between December 1993 and February 1997, 302 electronic data storage tags (DSTs), programmed to record depth at 10-min intervals and temperature daily, were attached to mature female plaice,Expand

Seasonal migration of thornback rays and implications for closure management
Sharks and rays are vulnerable to fisheries exploitation because of late maturation and low fecundity, highlighting the need for effective conservation strategies. Area closures have been proposed asExpand

Vertical activity patterns of free-swimming adult plaice in the southern North Sea
Analysis of continuous behaviour records of adult female plaice Pleuronectes platessa tagged with electronic data storage tags, and released in the southern North Sea, has yielded new insights intoExpand
