Scientists with the USGS Utah Cooperative Fish and Wildlife Research Unit are leading research on Utah’s native fish, the Bonneville cutthroat trout, a fish feared extinct in the 1970s. Researchers have monitored for fish abundance, density, distribution, size and age for nearly two decades.

The dam impounding Merwin Reservoir on the Lewis River, a tributary of the lower Columbia River, has blocked salmon passage for decades.

Hawaiian fishponds were important cultural and economic resources for native Hawaiians as they were an important component of a sophisticated, integrated food production system. However, changing demographics and systems of land ownership resulted in a decline in the use and upkeep of Hawaiian fishponds throughout the 19th century.

However, changing demographics and systems of land ownership result in declines in the use and upkeep of Hawaiian fishponds throughout the 19th century.

Throughout Hawaii, fishponds are considered by their local communities as important cultural touchstones, a source of local, sustainably produced food, and an important component to the development of community-based management for nearshore fisheries.
