Associate Editor, Hedley Grantham, introduces this month’s Editor’s Choice article by Lia Chalifour and colleagues, which evaluates the potential benefits of 14 management strategies on 19 conservation units of the five Pacific salmon species in the lower Fraser River, British Columbia, Canada. Salmon are an iconic and globally recognisable species. In the Northeast Pacific they are also an important commercial and recreational fish species with … Continue reading Editor’s Choice 58:9 Identifying a pathway towards recovery for depleted wild Pacific salmon populations in a large watershed under multiple stressors
Associate Editor, Maria Paniw, introduces this month’s Editor’s Choice article by Dasnon et al., which presents some good news for seabird conservation: combined efforts of avoiding bycatch from commercial fisheries and reducing impacts of invasive species can effectively boost population sizes of vulnerable marine pelagic species. Industrial fishing activities can cause substantial damage, not only to fish stocks but also to pelagic vertebrate predators that … Continue reading Editor’s Choice 59:7 The key to seabird conservation – mitigating bycatch from industrial fisheries and eradicating invasive species
There is mounting evidence that climate change is affecting commercial fish species. In their latest research, Ikpewe and colleagues investigate the effect of temperature on fish sizes in two neighbouring regions, displaying contrasting trends in warming. The warming of our oceans due to climate change is affecting marine life in numerous ways. Fish populations, in particular, are experiencing changes in productivity, distribution, growth and the … Continue reading Smaller adults and bigger juveniles: how global warming is affecting our fish populations.
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. Combining knowledge on the local benthos community and the results of this study, managers will now be able … Continue reading Benthos longevity matters …
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
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?
From fisheries management, to reintroductions and land use policies, here are some highlights from issue 55:3: Addressing global fisheries management challenges in a changing world Our latest Spotlight, showcasing high-quality and topical research Targeted supplementary feeding supports reintroduction of endangered raptors This issue’s Editor’s Choice Is environmental legislation conserving tropical stream faunas? Looking beyond the trees in tropical forest landscapes Evaluating the temporal effectiveness of marine reserves Species recovery … Continue reading Issue 55:3
From ecosystem productivity to economic benefits, issue 55:3 of Journal of Applied Ecology features a Spotlight on Fisheries management. Associate Editor, Stephanie Januchowski-Hartley brings the articles together and discusses the encouraging ways in which this research from temperate and tropical waters can inform management. Globally, hundreds of millions of people depend on marine and freshwater fisheries that are faced with mounting challenges and diverse issues … Continue reading Spotlight: Addressing global fisheries management challenges in a changing world
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
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
