Abstract:
... The Pacific hake (Merluccius productus) midwater trawl fishery is the largest groundfish fishery off the U.S. West Coast by volume. Catches comprise mainly Pacific hake, however, bycatch of Chinook salmon (Oncorhynchus tshawytscha) can be an issue affecting the fishery as Endangered Species Act (ESA) listed Evolutionarily Significant Units represent a portion of the total Chinook salmon bycatch. W ...

Abstract:
... Reference points identify benchmarks, thresholds, or decision points for fisheries management, and are commonly defined by stock status indicators that presume equilibrium population conditions in the absence of fishing (e.g., equilibrium biomass, B0). However, equilibrium population biomass may be an inappropriate reference level when stock productivity is influenced by environmental change, pred ...

Abstract:
... The Beverton-Holt stock-recruitment (SR) relationship has typically been reparameterized such that a single parameter, “steepness,” can be used to define recruitment compensation along a common scale. However, “steepness” is notoriously difficult to estimate in stock assessment models, particularly for the integrated analysis models used to assess groundfish stocks along the U.S. West Coast, due i ...

Abstract:
... In the U.S. West Coast groundfish bottom trawl fishery, lengthy sweeps (>85 m) that maintain seafloor contact are traditionally used. While these sweeps are effective at herding groundfishes, their bottom tending characteristics increase the potential to cause seafloor disturbances, and injury and unobserved mortality to benthic organisms. In this study, we examined if changing from conventional t ...

Abstract:
... Stock assessments based on the integrated paradigm often include an underlying stock-recruitment relationship. This, along with estimates of fishery selectivity and biological parameters, allows the biomass and fishing mortality associated with Maximum Sustainable Yield (BMSY and FMSY respectively) to be calculated. However, the estimates of these quantities may differ from the proxies assumed in ...

Abstract:
... Geolocation is increasingly employed to reconstruct the movements of demersal fishes using data retrieved from electronic archival tags. However, geolocation methods commonly suffer from limitations such as low horizontal resolution of locations, flawed land boundary treatment, and extensive computation time. We addressed these issues using a state-space approach based on the particle filter (PF), ...

Abstract:
... The bluemouth, Helicolenus dactylopterus (Delaroche 1809), is a marine demersal fish that is widely distributed in the Atlantic and the Mediterranean. It is targeted by longline fisheries around the Iberian Peninsula and it is a common by-catch associated with many demersal fisheries. However, limited information exists about the population structure in the NE Atlantic and Mediterranean. Thus, the ...

Using an information-theoretic approach, we found that community composition ...

Although climate‐induced shifts in fish distribution have been widely reported at the population level, studies that account for ontogenetic shifts and subregional differences when assessing responses are rare.In this study, groundfish distributional changes in depth, latitude, and longitude were assessed at different size classes by species within nine subregions. We examined large, quality‐contr ...

Abstract:
... The seascape of the vast Australian continental margin is characterised by numerous submarine canyons that represent an equally broad range of geomorphic and oceanographic heterogeneity. Theoretically, this heterogeneity translates into habitats that may vary widely in their ecological characteristics.
