Incoherent dimensionality in fisheries management: consequences of misaligned stock assessment and population boundaries

Autor: Dana H. Hanselman, Katelyn M. Bosley, Amy M. Schueller, Jonathan J. Deroba, Brian J. Langseth, Daniel R. Goethel, Aaron M. Berger

Publikováno v: ICES Journal of Marine Science. 78:155-171

Fisheries policy inherently relies on an explicit definition of management boundaries that delineate the spatial extent over which stocks are assessed and regulations are implemented. However, management boundaries tend to be static and determined by

The Hawaiian deep-slope (75–400 m) Deep7 bottomfish fishery consists of seven (i.e., six snappers and one grouper) species. This study developed a sampling survey and modeling methodology for estimating biomass for this complex in the Main Hawaiian

Distinguishing species-specific targeting practices within the main Hawaiian islands Deep 7 bottomfish fishery

Autor: Sarah Glover, Brian J. Langseth

Publikováno v: Fisheries Research. 244:106105

The main Hawaiian islands Deep 7 bottomfish fishery is a multispecies fishery that uses hook-and-line gear to catch seven primary species and is currently managed and assessed as a single population. Management plans support, and recent assessment re

Calculation of population-level fishing mortality for single- versus multi-area models: application to models with spatial structure

Autor: Brian J. Langseth, Amy M. Schueller

Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 74:1821-1831

Spatial considerations in stock assessment models can be used to account for differences in fish population dynamics and fleet distributions, which, if otherwise unaccounted for, could result in model misspecification leading to bias in model results

Aerial survey as a tool for understanding bigeye scad (Selar crumenophthalmus) dynamics around the island of O'ahu, Hawai’i

Autor: Brian J. Langseth, John Wiley, Marlowe Sabater

Publikováno v: Fisheries Research. 236:105866

The bigeye scad (Selar crumenophthalmus) supports one of the most productive near-shore fisheries in Hawai'i. Fishing boats frequently work in tandem with spotter planes to efficiently target bigeye scad schools. These spotter planes provide the mean

Management implications of temporally and spatially varying catchability for the Gulf of Mexico menhaden fishery

Autor: Brian J. Langseth, Joseph W. Smith, J. Kevin Craig, Kyle W. Shertzer, Amy M. Schueller

Publikováno v: Fisheries Research. 181:186-197

Catchability relates fishing effort to fishing mortality, and is an important component in fishery stock assessment models. Mis-specifying catchability can lead to inaccurate estimation of model parameters and bias in the determination of stock statu

Overcoming challenges of harvest quota allocation in spatially structured populations

Ignoring spatial population structure in the development of fisheries management advice can affect population resilience and yield. However, the resources required to develop spatial stock assessment models that match the spatial scale of management

Influence of fishing practices on lake trout bycatch in the Canadian lake-whitefish commercial fishery in Lake Huron

Autor: Brian J. Langseth, Adam Cottrill

Publikováno v: Journal of Great Lakes Research. 41:280-291

Rehabilitation of lake trout ( Salvelinus namaycush ) populations is a priority for fisheries management in the upper Laurentian Great Lakes. In Lake Huron, lake trout are frequently caught as bycatch in the commercial fishery for lake whitefish ( Co
