Bering Sea fishing group grapples with how to invest pollock profits in Western Alaska
Amid declining salmon runs, Coastal Villages Region Fund has shifted away from subsidizing village-based seafood processing. Coastal Villages used to pursue that mission in large part by operating smaller commercial fisheries for salmon and halibut. Each year, the fishing season was an opportunity to earn wages at the group’s processing facilities or for local fishermen to earn cash selling their catch — an economic lifeline for many families in one of the state’s poorest regions.

Hooper Bay's dunes, home to the community’s cultural history, are slipping into the sea
The sand dunes in Hooper Bay, Alaska, which serve as a protective barrier against storms and preserve the community's cultural history, are rapidly eroding and may lead to the relocation of the village. The dunes were once home to sod houses and artifacts dating back to 1600 A.D. The loss of the dunes threatens not only subsistence food resources but also the community's connection to its past. As the dunes continue to erode, there are concerns about the potential relocation of the community and the preservation of their stories and artifacts.
