Bottom‐Up Interactions in State‐Space Age‐Structured Models Using Mass‐Balance Dynamics

Fish and Fisheries, Volume 26, Issue 6, Page 1048-1064, November 2025.
ABSTRACT Age‐structured models are used worldwide to regulate fisheries. These models typically ignore top‐down interactions (predation affecting natural mortality) and bottom‐up interactions (consumption affecting individual growth, reproduction, or survival), whereas multispecies catch‐at‐age models often incorporate top‐down but not bottom‐up ...

MODELING SPECIES DISTRIBUTIONS: APPLICATIONS AND METHODS FOR MARINE BIOGEOGRAPHY AND CONSERVATION [PDF]

, 2015
I employed multidisciplinary approaches for understanding distributions of marine fishes in the present, past, and future, and for considering more broadly the historical role of primary research in policy decisions.

Drivers and Dynamics of Salmon Bycatch in the Eastern Bering Sea Pollock Fishery

Fish and Fisheries, Volume 26, Issue 6, Page 1107-1121, November 2025.
ABSTRACT Minimising bycatch is a pervasive challenge for sustainable fisheries management, the importance of which is amplified for non‐target species or populations that are in decline. In the eastern Bering Sea (EBS) walleye pollock (Gadus chalcogrammus) fishery, salmon—most notably Chinook (Oncorhynchus tshawytscha) and chum (O.

Otolith radiocarbon signatures provide distinct migration history of walleye pollock around Hokkaido, Japan in the North‐Western Pacific

Ecology and Evolution
Trace elements and stable isotope ratios in otoliths have been used as proxies for the migration history of teleosts; however, their application in oceanic fishes remains limited.

Saxitoxin Linked to Deaths of Northern Fur Seals in the Southeast Bering Sea

Marine Mammal Science, Volume 41, Issue 4, October 2025.
ABSTRACT In August 2024, a northern fur seal mortality event was observed on St. Paul Island, AK in the southeast (SE) Bering Sea. Ten seals in good body condition were found dead along with large accumulations of dead fish on Benson Beach located on St. Paul Island.

Fluid preservation causes minimal reduction of parasite detectability in fish specimens: A new approach for reconstructing parasite communities of the past?

Ecology and Evolution, 2020
Long‐term datasets are needed to evaluate temporal patterns in wildlife disease burdens, but historical data on parasite abundance are extremely rare. For more than a century, natural history collections have been accumulating fluid‐preserved specimens ...

Using Vessel Monitoring System Data to Identify and Characterize Trips Made by Fishing Vessels in the United States North Pacific.

PLoS ONE, 2016
Time spent fishing is the effort metric often studied in fisheries but it may under-represent the effort actually expended by fishers. Entire fishing trips, from the time vessels leave port until they return, may prove more useful for examining trends in

DNA Barcode como ferramenta molecular na identificação de fraude de bacalhau salgado (Gadus morhua, Gadus macrocephalus e Gadus ogac) comercializado em Porto Alegre, RS, Brasil [PDF]

, 2022
A fraude de produtos de pescado é um problema em nível mundial, especialmente devido às características da cadeia produtiva, que inclui o beneficiamento prévio dos peixes nas embarcações, ainda em alto-mar, além das semelhanças morfológicas entre as ...
