Benthos longevity matters …

Long-lived species take longer to recover from the effects of bottom trawling by commercial fisheries according to recent research from Hiddink et al. Watch this video from PROJECT BENTHIS to discover more about the importance of longevity and benthic animal traits. Introduction by Associate Editor, Verena Trenkel. Bottom trawling by commercial fisheries affects not only the target species — typically fish and shellfish — but … Continue reading Benthos longevity matters …

Dynamic technology for dynamic ecosystems

When it comes to developing management tools, how do we keep up with constantly changing ecosystems? Associate Editor, Annabel Smith explains the important step forward made by Welch et al’s research into dynamic management tools. Scientists have been very good at developing guidelines for management of natural systems. Streams of conceptual frameworks are published every year, to the point that we now have frameworks for … Continue reading Dynamic technology for dynamic ecosystems

Should we care if angler participation patterns are different?

Fisheries management approaches need to consider angler behaviour, or there could be knock-on effects once practices are implemented. Synchrony – an emergent property of recreational fisheries by Kaemingk et al. is published today in Journal of Applied Ecology. Understanding how people use natural resources in space and time is challenging, but necessary for proper management.  Biologists often face difficult and urgent management decisions; these decisions may … Continue reading Should we care if angler participation patterns are different?

Tracking an apex marine predator – the shortfin mako shark

In this post Jeremy Vaudo and Mahmood Shivji discuss their article ‘Long-term satellite tracking reveals region-specific movements of a large pelagic predator, the shortfin mako shark, in the western North Atlantic Ocean’ In your paper you used satellite telemetry to investigate movements and seasonal distributions of shortfin mako sharks (Isurus oxyrinchus) in the western North Atlantic Ocean. What were the biggest challenges for this work? … Continue reading Tracking an apex marine predator – the shortfin mako shark

Fine-scale salmon diversity sustains fisheries and supports food security of indigenous communities

A new study from Holly Nesbitt and Jonatahn Moore at Simon Fraser University shows that high biodiversity in salmon fisheries supports the food security of indigenous people. Salmon-folios Instead of analyzing market returns of different financial portfolios, this study examined indigenous fisheries with different “salmon-folios”. Like a well-balanced financial portfolio that can smooth market fluctuations, fisheries that caught a more diverse portfolio of salmon populations … Continue reading Fine-scale salmon diversity sustains fisheries and supports food security of indigenous communities

New spatio-temporal model improves the ability of fishery managers to set sustainable catch limits

In this post Associate Editor Andre Punt discusses a paper he recently handled by James T. Thorson, Jason Jannot and Kayleigh Somers ‘Using spatio-temporal models of population growth and movement to monitor overlap between human impacts and fish populations‘ In many jurisdictions, including the U.S., conservation management of fish stocks involves comparing catches with estimates of an overfishing limit (OFL). The OFL is a catch … Continue reading New spatio-temporal model improves the ability of fishery managers to set sustainable catch limits

Environmental DNA and crayfish management

In this post Matthew Dougherty discusses his recent paper ‘Environmental DNA (eDNA) detects the invasive rusty crayfish Orconectes rusticus at low abundances‘ Tangled buoy strings, lost traps, pinched fingers, sweaty brows, and boats smeared with beef liver: these images define the experiences of countless managers and scientists who use baited trapping to monitor crayfish invasions, especially in lakes of the upper Midwest, USA. While these … Continue reading Environmental DNA and crayfish management

Dining out: Fish switch from an aquatic to a terrestrial-based diet in streams impacted from metal contamination

In this post Justin Pomeranz and David Walters discuss their recent paper ‘Aquatic pollution increases use of terrestrial prey subsidies by stream fish’ Have you ever walked next to a high elevation, Rocky Mountain stream? Picked your way through downed trees, pushing your way through thick willows, listening to the water pour and bounce over rocks and settle into plunge pools? Have you ever fished … Continue reading Dining out: Fish switch from an aquatic to a terrestrial-based diet in streams impacted from metal contamination
