The changing status of imperiled species in British Columbia over the last 15 years in the absence of a dedicated species at risk law Open
Gaps in biodiversity protection occur in Canada due to limited jurisdiction of federal species-at-risk laws and the absence of dedicated legislation in many provinces, including British Columbia (B.C.). While lacking legal protection, B.C.…

Habitat management and restoration as missing pieces in flats ecosystems conservation and the fishes and fisheries that they support Open
Flats ecosystems are dynamic, shallow, nearshore marine environments that are interconnected and provide immense ecological and socio-economic benefits. These habitats support a diversity of fish populations and various fisheries, yet they…

Marine Fish Passage—Underappreciated Threats to Connectivity Within the Marine Environment Open
Habitat fragmentation is a major threat to aquatic biodiversity loss. However, much of the focus is on the connectivity of freshwaters, with much less attention given to marine ecosystems. We contend that coastal infrastructure including b…

A review of migratory <i>Alosidae</i> marine ecology in the northwest Atlantic Open
Migratory animals play a crucial role in connecting distinct habitats by transferring matter and energy across ecosystem boundaries. In the North Atlantic, anadromous species exemplify this through their movement between freshwater and mar…

Evaluating the efficacy of ecological restoration of fish habitat in coastal waters of Lake Ontario Open
Ecological restoration is a common strategy applied to degraded wetlands and tributaries in large lakes. As resources are typically limited for restoration, it is essential to ensure that such efforts achieve associated goals. Using both d…

Interactive effects of fish handling and water temperature on reflex impairment of angled Rainbow Trout Open
Catch-and-release angling is a popular recreational activity that has been shown to have impacts on fish welfare. Angler behaviour (e.g., choice of gear type, handling time) and environmental conditions (e.g., water temperature) during ang…

Knowledge of spawning phenology may enhance selective barrier passage for wetland obligate fishes Open
Within the Laurentian Great Lakes, many native fishes use wetlands for spawning; however, these areas are also used by non-native common carp ( Cyprinus carpio ) that may impart negative ecological impacts. There is interest to manage comm…
