Examining the Impact of Derelict Pots on Blue Crab (Callinectes sapidus) Catch and Harvest Within a Recreational Fishery

Fisheries Management and Ecology, EarlyView.
ABSTRACT Derelict fishing gear can negatively affect marine ecosystems through mortality in coastal environments. This study explored the impact of derelict and active crab pots on recreational blue crab (Callinectes sapidus) catch rates and landings in a Mid‐Atlantic estuary by deploying experimental pots in four habitat strata within three sections ...

Recovery of Four Commercial Fish Stocks in Lake IJsselmeer (The Netherlands) After Major Fishery Management Interventions

Fisheries Management and Ecology, EarlyView.
ABSTRACT Sustainable management of inland fisheries presents major challenges because it often involves complex and open access systems. Lake IJsselmeer is among the largest freshwater lakes in western Europe and supports active commercial fisheries.

Stable species boundaries despite ten million years of hybridization in tropical eels

Nature Communications, 2020
In the Indo-Pacific, multiple Anguilla eel species overlap in their spawning. Here, the authors sequence three Anguilla genomes and with genome-wide data of four more congeners, investigate contemporary hybridization, historical introgression, and the ...

Expression of corticoid‐regulatory genes in the gills of Atlantic salmon (Salmo salar) parr and smolt and during salinity acclimation

Journal of Fish Biology, EarlyView.
Abstract In teleost fishes, cortisol is the major corticoid and has both glucocorticoid and mineralocorticoid actions. However, how fish tissues discriminate between these distinct corticosteroid actions is unclear. In mammals, the major factors responsible for intracellular corticosteroid regulation are glucocorticoid receptors (grs) and the ...

A comparison of European eel Anguilla anguilla eDNA concentrations to fyke net catches in five Irish lakes

Environmental DNA, 2020
The European eel, Anguilla anguilla, is classified as critically endangered by the IUCN. To protect what remains of the European eel population, accurate monitoring methods for this species are important.

Implications of the first recording of European silver eels Anguilla anguilla in the inland waters of Cyprus

Journal of Fish Biology, EarlyView.
Abstract Migrating silver European eels Anguilla anguilla are reported from the inland waters of the island of Cyprus for the first time, expanding the known geographic range in the Eastern Mediterranean of emigrating adults of this critically endangered, catadromous species.

Assessment of two minimally invasive methodologies for sex identification in the European eel, Anguilla anguilla

Journal of Fish Biology, EarlyView.
Abstract Sex is an important driver of variation in behaviour, ecology and physiology. Sex identification in the Critically Endangered European eel (Anguilla anguilla) currently requires fish sacrifice, or the use of morphological differences such as body length, which can be inaccurate in certain habitats and at intermediate body lengths.

Pseudodactylogyrosis in Anguilla anguilla (Actinopterygii: Anguilliformes: Anguillidae): change of control strategies due to occurrence of anthelmintic resistance [PDF]

Acta Ichthyologica et Piscatoria, 2011
Background. The European eel, Anguilla anguilla (L.), is considered an endangered species and a series of protective measures have been implemented within the European community in order to enhance natural stocks.

Points vs. passes: A comparison between electric fishing techniques for sampling fish populations in upland headwater streams

Journal of Fish Biology, EarlyView.
Abstract Point‐abundance sampling by electric fishing (PASE) was compared with single‐pass (DF1) and triple‐pass depletion sampling (DF3) electric fishing on the same reaches of four headwater streams sampled over multiple years in the Ribble catchment, UK. Juvenile salmonids, mostly brown trout Salmo trutta with some Atlantic salmon S.
