Saving Seafood

Alaska SeaLife Center Collaborates with NOAA

October 27, 2016 — SEWARD, Alaska — Scientists from the Alaska SeaLife Center (ASLC) recently returned from the first research mission to utilize new satellite technology for the study of harbor seal populations.

The month-long expedition to the Aleutian Islands on board the research vessel Norseman, was conducted in collaboration with the National Oceanic and Atmospheric Administration’s (NOAA) Polar Ecosystems Program.

“The population trends and factors that may be influencing harbor seals remain poorly understood,” said ASLC President and CEO Tara Riemer. “We are excited to increase our understanding of harbor seals and for the potential to better inform the science community and resource managers.”

Co-funded by the National Oceanic and Atmospheric Administration, the study brings together scientists from two different organizations to collaborate on the next steps toward understanding and addressing shared concerns. Using Life History Transmitters (LHX), developed by Dr. Markus Horning, ASLC Science Director, in collaboration with Wildlife Computers, Inc. under funding from the National Science Foundation, researchers will be able to collect survival and reproductive data to better understand harbor seal population trends.

Pacific cod eating seabirds, study shows

November 9, 2015 — You could call it revenge on the birds.

While many marine birds are well known for their skills at diving into the sea to pluck out fishy meals, there is now solid evidence that some Pacific cod have turned the tables on the avian species.

The practice came to light a few years ago when seafood workers in Dutch Harbor noticed that some of the cod they were processing came with extra features — partially digested birds in the fish stomachs.

Scientists from the Alaska SeaLife Center and University of Alaska have now examined remains of 74 birds collected from cod stomachs in 2011 and have some findings described in a study published online in the journal Marine Ornithology.

The bird remains come from cod caught in the Aleutian Islands region, off Cape Sarichef in Unimak Pass, using trawl and pot gear. The fish were processed at the UniSea plant in Dutch Harbor; the plant froze the bird remains and sent them to the scientists for analysis.

There have been other known cases of big fish eating small seabirds elsewhere in the world, the new study says, and past surveys by the National Oceanic and Atmospheric Administration have turned up, in very rare instances, bits of birds inside cod. In one case, a NOAA researcher found a murre foot in a cod stomach.

But the evidence from Dutch Harbor appears to be the first documentation of Pacific cod making a practice of eating birds, said study co-author Tuula Hollmen, science director at the SeaLife Center and an associate professor at the University of Alaska Fairbanks’ School of Fisheries and Ocean Sciences.
