Hawaii’s native freshwater fish are migratory and must travel between the sea and interior island streams to complete their life cycle. These fish are from the goby family and are called oʻopu in the Hawaiian language. In addition, there are numerous fish species such as ʻama (grey mullet) and papio (jacks) that inhabit Hawaii’s estuaries and regularly transit between river mouth estuaries and adjacent coral reefs.
The Hawaiʻi World Fish Migration Day event will take place May 21st, 2022 at the Heʻeia Estuary Restoration Project site on the island of Oʻahu. This stream restoration site is located within a Hawaiʻi State Park and the project is led by the regional non-profit environmental organization Hui O Koolaupoko. The stream mouth estuary is also within the Heʻeia National Estuarine Research Reserve where federal, state, and community-based partners contribute to the restoration and study of watershed and estuary characteristics and Indigenous aquaculture.
In recognition of World Fish Migration Day, volunteers will contribute to on-going work to remove invasive woody vegetation that severely restricts the waterway and limits upstream/downstream migration of native aquatic species. Participants will provide hands-on assistance to help re-establish native riparian plants and maintain previously-cleared streambanks.
