Ecosystem-based Management for Protected Species in the North Pacific Fisheries [PDF]

, 2011
In the North Pacific Ocean, an ecosystem-based fishery management approach has been adopted. A significant objective of this approach is to reduce interactions between fishery-related activities and protected species.

Molecular Mechanisms Underlying Response to Influenza in Grey Seals (Halichoerus grypus), a Potential Wild Reservoir

Molecular Ecology, Volume 34, Issue 15, August 2025.
ABSTRACT RNA viruses are infamous for their ability to cross species barriers, posing threats to global health and security. Influenza A virus (IAV) is naturally found in avian hosts but periodically spills over into marine wildlife. IAV outbreaks occur in the Northwest Atlantic, but grey seals (Halichoerus grypus) appear to be less susceptible to IAV ...

Distribution and Abundance of Steller Sea Lions, Eumetopias jubatus, on the Asian Coast, 1720's-2005 [PDF]

, 2005
We analyzed published and archived records for the past 250 years to assess changes in distribution and abundance of Steller sea lions, Eumetopias jubatus, along the Asian coast from the Bering Strait to the Korean Peninsula.

How Fragmented Is eDNA? A Case Study on Shark DNA in Tropical Reef Seawater

Environmental DNA, Volume 7, Issue 4, July–August 2025.
This study quantified mitochondrial eDNA fragment lengths in offshore tropical seawater using qPCR assays targeting amplicons from 119 to 15,727 bp in tiger shark (Galeocerdo cuvier). Copy numbers steeply declined with increasing fragment size, with successful amplification up to 1518 bp and a calculated mean undamaged fragment size of 256 bp.

Winter movements and long-term dispersal of Steller sea lions in the Glacier Bay region of Southeast Alaska

Endangered Species Research, 2018
Steller sea lions Eumetopias jubatus in the Glacier Bay region of northern Southeast Alaska experience greater survival and more rapid population growth than sea lions elsewhere in this region. To better understand demographics of sea lions in the region,

Understanding early ontogeny and whisker growth dynamics of Weddell seal (Leptonychotes weddellii) pups through stable isotope analysis

Marine Mammal Science, Volume 41, Issue 3, July 2025.
Abstract Stable isotope analysis of animal tissues is a valuable tool for understanding foraging ecology, habitat use, and developmental changes throughout an animal's life. Stable isotope values of whisker segments offer long‐term data on mammalian foraging, as whisker growth incorporates isotopic signals from the diet and reflects dietary shifts ...

Natal and breeding philopatry of female Steller sea lions in southeastern Alaska.

PLoS ONE, 2017
Information on drivers of dispersal is critical for wildlife conservation but is rare for long-lived marine mammal species with large geographic ranges.

A method to improve size estimates of walleye pollock (Theragra chalcogramma) Atka mackerel (Pleurogrammus monopterygius) consumed by pinnipeds: digestion correction factors applied to bones and otoliths recovered in scats [PDF]

, 2004
The lengths of otoliths and other skeletal structures recovered from the scats of pinnipeds, such as Steller sea lions (Eumetopias jubatus), correlate with body size and can be used to estimate the length of prey consumed.

The First Satellite Flipper Tag Deployments on Steller Sea Lions Allow Tracking Beyond the Annual Molt

Marine Mammal Science, Volume 41, Issue 3, July 2025.
ABSTRACT Entanglement in marine debris and fishing gear is increasingly recognized as a serious source of human‐caused mortality for pinniped population world‐wide and has been shown to contribute to Steller sea lion injury and mortality. As such, our primary goal in testing these location‐only satellite flipper tags was to track post‐entanglement ...

Trends and Potential Interactions Between Pinnipeds and Fisheries of New England and the U.S. West Coast [PDF]

, 2000
Long-term trends in the abundance and distribution of several pinniped species and commercially important fisheries of New England and the contiguous U.S. west coast are reviewed, and their actual and potential interactions discussed.
