Use of a reciprocal transplant study to measure the rate of plant community change in a tidal marsh along a salinity gradient [PDF]

, 2004
Freshwater reclaimed marshes along the European Atlantic coast are highly suitable for European eels (Anguilla anguilla). However, European eel stocks have declined, and the coastal marshes have been subjected to major disturbances.

Downstream Passage Performance of European Silver Eels (Anguilla anguilla): The Importance of Phenotypic Variation and Rack Design

Animal Conservation, EarlyView.
During their spawning migration, European silver eels frequently encounter hydropower facilities where successful downstream passage is essential for the conservation of this critically endangered species. In this study, we evaluated how three angled rack designs and individual behavioral variation influenced downstream passage success in large‐scale ...

Spatial distribution of an eel population (Anguilla anguilla L.) in a small coastal catchments of northern Brittany (France). Consequences hydraulic works. [PDF]

, 1998
The Frémur is a 60 km2 catchment of Brittany where many hydraulic works (dams, weirs, gauging structures, etc.) have reduced the recruitment by elvers and glass eels since at least 50 years.

Behavioural Diversity of Fishes: Concepts, Drivers and Its Role in Conservation and Management

Fish and Fisheries, EarlyView.
ABSTRACT Human activity has altered nearly all ecosystems on Earth, contributing to substantial biodiversity loss across taxonomic, genetic and functional dimensions, from the intraspecific to the ecosystem scale. Yet some components of biodiversity remain hidden or underappreciated, including behavioural diversity.

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 ...

Minimal and maximal size of eel

Knowledge 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.

Biogeography of Atlantic Salmon in the Cape Breton Highlands, Canada

Fisheries Management and Ecology, EarlyView.
ABSTRACT Atlantic Salmon (Salmo salar) populations have experienced significant declines in recent decades. In Canada, conservation efforts are divided into 16 designatable units (DUs) to address unique regional challenges among genetically distinct populations.
