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

open access: yesFisheries 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.

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

open access: yesJournal 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 ...

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

open access: yesJournal 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

open access: yesJournal 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.

Minimal and maximal size of eel

open access: yesKnowledge and Management of Aquatic Ecosystems, 1998
At the occasion of the catch of a giant eel in the Netherlands, it was realized extreme sizes listed in literature are quite arbitrary chosen. A first attempt to derive true values was undertaken.

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

open access: yesJournal 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.

Integrating environmental DNA, diving surveys and DNA barcoding to track endangered twaite shad (Alosa fallax) spawning sites

open access: yesJournal of Fish Biology, EarlyView.
Abstract The twaite shad (A. fallax), an anadromous fish species belonging to the Clupeidae family, has experienced population declines throughout Europe. This decline is attributable to a range of anthropogenic pressures, including migration barriers, environmental pollution, habitat degradation, predation by invasive species and unsustainable fishing

Partial nocturnal behaviour of giant mottled eels, Anguilla marmorata, in a small river, Amami‐Oshima Island, Japan, from acoustic telemetry

open access: yesJournal of Fish Biology, EarlyView.
Abstract Anguillid eels typically exhibit nocturnal behaviour, but giant mottled eels A. marmorata are often observed during daytime in rivers on Amami‐Oshima Island, Japan. We investigated their diel activity patterns and spatial use with stationary‐receiver acoustic telemetry.
