Frontiers in Marine Science, 2020 In 2014–2016 an unprecedented warming event in the North Pacific Ocean triggered changes in ecosystem of the Gulf of Alaska (GOA) impacting fisheries management. The marine heatwave was noteworthy in its geographical extent, depth range, and persistence,

FACETSWe used isodars, developed from the ideal free distribution (IFD), to predict the distribution of fishing effort across regulatory boundaries in the south-western Scotian Shelf’s haddock fishery.

An Econometric Model of the Market for New England Groundfish [PDF]
Northeastern Journal of Agricultural and Resource Economics, 1985 This paper develops an economic model of the New England groundfish market. A multi-sector, multi-level econometric model is estimated using data from 1970 to 1982. The parameters of the estimated model are used to characterize consumer demand for groundfish and related products.

Ichthyophonus in sport-caught groundfishes from southcentral Alaska [PDF]
Diseases of Aquatic Organisms, 2018 This report of Ichthyophonus in common sport-caught fishes throughout the marine waters of southcentral Alaska represents the first documentation of natural Ichthyophonus infections in lingcod Ophiodon elongates and yelloweye rockfish Sebastes ruberrimus. In addition, the known geographic range of Ichthyophonus in black rockfish S.

Polar cod Boreogadus saida occurrence is driven by temperature at the margin of its distribution
Journal of Fish Biology, EarlyView.Abstract With a warming Arctic, suitable habitat for polar cod Boreogadus saida (Lepechin 1774) is predicted to decrease. We investigated the changes in distribution of polar cod on the southern limit of its distribution in the Atlantic Ocean (around Iceland) during both autumn and spring after a recent period of warming in the area.

Journal of Fish Biology, EarlyView.Abstract Patagonian toothfish (Dissostichus eleginoides) are a long‐lived, slow‐growing deep‐sea species endemic to the Southern Hemisphere and the focus of longline fisheries managed to ensure sustainable exploitation. Managing the fisheries relies on accurate stock assessments that include pertinent biological and exploitation processes.

Testing of a helix twine off-bottom trawl on Georges Bank
Frontiers in Marine Science, 2023 The massive biomass of Eastern Georges Bank haddock (Melanogrammus aeglefinus) is difficult to harvest without capturing less robust, but still valuable groundfish stocks like Atlantic cod (Gadus morhua) and some flatfish species.

Maternal effects on recruitment of five gadoid species
Marine Ecology, EarlyView.Abstract Commercial fishing is almost always non‐random and generally removes large and old individuals from fish stocks, thereby reducing age diversity among spawners. Reduced age diversity may result in less stable recruitment. Here, we explore the influence of age diversity (H), mean age of the spawning stock (MA) and sea surface temperature (SST ...

Trends in Pacific Canadian groundfish stock status [PDF]
, 2021 Abstract We assembled estimated biomass (B) time series from stock assessments for 24 Pacific Canadian groundfish stocks and modelled average and stock status through 2020 based on biomass relative to each stock’s (1) Limit Reference Point (B/LRP), (2) Upper Stock Reference (B/USR), and (3) biomass at maximum ...
