The public is invited to a mo'i release event tomorrow behind the Waikiki Aquarium.

The fish will be released from 11 a.m. to 11:30 a.m. by schoolchildren.

Following the release event, from noon to 1 p.m., remarks on Earth Day will be made at the aquarium stage by the mayor, University of Hawai'i officials and others.

Also tomorrow, volunteers will gather at Manoa Stream to capture armored catfish.

The event starts at 10:30 a.m., weather and stream conditions permitting.

Members of the public are invited to watch at the bridges at Lowrey Avenue or East Manoa Road.

The event is aimed at bringing attention to the problem of alien species in Hawai'i freshwater streams.

Both events are being organized by the state Department of Land and Natural Resources and the Waikiki Aquarium.
