Partnership - Hawaii Fish Habitat Partnership Anchialine pools represent an inland waterbody type that is widespread but threatened throughout the Hawaiian Islands and is a key habitat type of concern to the Hawaii Fish Habitat Partnership. Anchialine pools, also known as fishponds in Hawaii, are near the coast and are land-locked bodies of water that have connections both to the sea, typically by high tides, as well as to local freshwater. These systems have been used for thousands of years for fish production by Native Hawaiians. The majority of remaining fishpond pools are located on the Kona coast and southern coastlines of the Big Island, the southeast coast of Maui, and on several small and widely separated...
Partnership - Hawaii Fish Habitat Partnership The Waipa Stream flows from lower Mount Waialeale to Hanalei Bay on the north shore of Kauai, Hawaii. Much of the upper Waipa Stream system still exhibits good quality aquatic habitat. However, the lower reaches of Waipa Stream were significantly degraded due to widespread and dense overgrowth of an invasive riparian tree known as hau ( Hibiscus tiliaceus). The in-stream habitat available for native aquatic fish and invertebrates was reduced by hau growth in the stream causing sediment and plant debris to fill up a stretch of the stream channel and creating unnatural barriers for migrating native fish and prawns that have to pass through this section of the stream...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
