AFSC Study Looks at Range of eDNA in Marine Fisheries Management

New research by the Alaska Fisheries Science Center (AFSC) in Juneau examines the influence of distance and tides on distribution and concentration of environmental DNA from chum salmon in net pens in Southeast Alaska. It’s another piece of the puzzle as researchers work to understand the overall impact of changing climate conditions on fisheries in the ocean. This study, AFSC research geneticist Diana Baetscher said, addresses one of the critical knowledge gaps in applying eDNA to marine fisheries management. “The idea here is we are able to use eDNA to understand where the fish are,” she said. “What we did with the chum hatchery net pen in Juneau was an experiment to determine where we no longer detect this eDNA. It is just a piece of information floating around in the water...

NOAA Fisheries Study Looks at Future of Pacific Cod Moving North

A new study, publicly released June 22 by NOAA Fisheries’ Alaska Fisheries Science Center (AFSC), says the success of reproduction of Pacific cod moving north because of climate change issues remains an unknown. New collaborative research discussed in the study predicts how thermally suitable habitat for Pacific cod spawning in the Bering Sea may shift over the coming century of climate change. The study coupled state-of-the-art climate modeling with information from laboratory experiments relating hatch success to temperature and looked at how changes in spawning habitat might affect Pacific cod productivity. The study projects that suitable spawning habitat will expand and shift over this century, as current spawning hotspots likely become too warm for egg development and ha...

AFSC Speeds Up Data Collection To Tackle Bycatch Issues

Researchers with the Alaska Fisheries Science Center (AFSC) say they’re speeding up the process of gathering data to share with the fisheries managers and others on the decline of Chinook and chum salmon runs, particularly in western Alaska. The AFSC, which is collaborating with state and federal researchers, as well as those at the university level, reported in late August that the center has developed models to better understand and help resource managers address bycatch impacts. “These models, after accounting for natural mortality, produce estimates of the number of adult fish that would be expected to return to their natal rivers to spawn if they hadn’t been taken as bycatch in the Eastern Bering Sea Pollock fisheries,” their report states. Salmon bycatch levels vary year...

AFSC Research Plan Focuses on Shellfish, Seaweed Aquaculture Development

A strategic research plan released by the Alaska Fisheries Science Center (AFSC) will be used to help the NOAA Fisheries agency guide research to expand shellfish and seaweed production over the next five years, in hopes of expanding the state’s blue economy. The goal is to provide information for state and federal regulatory agencies and coastal communities in Alaska to ensure a sustainable seafood supply and economic opportunities for Americans. This research will provide an important foundation for sustainable development, AFSC Director Bob Foy said. “Marine aquaculture contributes to restoration efforts in Alaska and is increasing economic opportunities for coastal communities through the farming of shellfish and seaweed,” Foy explained. The research plan notes that the...
