Global status of groundfish stocks [PDF]

open access: yesFish and Fisheries, 2021
AbstractWe review the status of groundfish stocks using published scientific assessments for 349 individual stocks constituting 90% of global groundfish catch. Overall, average stock abundance is increasing and is currently above the level that would produce maximum sustainable yield (MSY).

Evaluating potential changes to the US Chukchi Sea bottom trawl survey design via simulation testing

open access: yesFrontiers in Marine Science, 2023
The US Chukchi Sea consists of the waters off the northwest of Alaska and is a naturally dynamic ice-driven ecosystem. The impacts from climate change are affecting the Arctic marine ecosystem as well as the coastal communities that rely on healthy ...

Evaluating the impacts of reduced sampling density in a systematic fisheries-independent survey design

open access: yesFrontiers in Marine Science, 2023
Fisheries-independent surveys provide critical data products used to estimate stock status and inform management decisions. While it can be possible to redistribute sampling effort to improve survey efficiency and address changing monitoring needs in the

Exploring variability in the diet of depredating sperm whales in the Gulf of Alaska through stable isotope analysis [PDF]

open access: yesRoyal Society Open Science, 2020
Sperm whales interact with commercially important groundfish fisheries offshore in the Gulf of Alaska (GOA). This study aims to use stable isotope analysis to better understand the trophic variability of sperm whales and their potential prey, and to use ...

Developing a longline/jig sentinel survey program for an area with limited monitoring and fishing efforts

open access: yesAquaculture and Fisheries, 2020
Areas, such as coastal eastern Gulf of Maine (GOM), perceived to have low density of target fish species and having high density fixed gear, are often subject to low fishing pressure and not well monitored.

Effects of management tactics on meeting conservation objectives for Western North American groundfish fisheries. [PDF]

open access: yesPLoS ONE, 2013
There is considerable variability in the status of fish populations around the world and a poor understanding of how specific management characteristics affect populations.

A Comparison of Fish Diversity in Rocky Reef Habitats by Multi-Mesh Gillnets and Environmental DNA Metabarcoding

open access: yesFrontiers in Ecology and Evolution, 2022
This study was undertaken in order to explore the practical effectiveness of the environmental DNA (eDNA) metabarcoding approach in evaluating fish composition and diversity in a high heterogeneous rocky reef habitat. We assessed the fish composition and

Spatial reference points for groundfish [PDF]

open access: yesICES Journal of Marine Science, 2016
AbstractAccording to density-dependent habitat selection theory, areas of high density can be indicative of high population productivity and have positive individual fitness consequences. Here, we explore six groundfish populations on the Scotian Shelf, Canada, where a decline in areas of high density beyond a certain threshold is associated with ...

Elasmobranch bycatch in US West Coast groundfish fisheries

open access: yesEndangered Species Research, 2021
Effective management of multispecies fisheries in large marine ecosystems is challenging. To deal with these challenges, fisheries managers are moving toward ecosystem-based fishery management (EBFM).

Recommendations for full-spectrum sustainability in Canadian lobster integrated management plans based on a socioeconomic analysis of Barrington, Nova Scotia

open access: yesEcology and Society, 2018
Fisheries and Oceans Canada has developed integrated fisheries management plans to promote a more holistic approach to fisheries management. Yet these management plans maintain an emphasis on the ecological domains, without sufficient attention to ...
