International and Statewide Symposia on Anchialine Ecosystems:

HWF is co-hosting the 5th International Symposium for Anchialine Ecosystems or “5ISAE” in Kona November 2022, along with staff and volunteers from The Nature Conservancy, the Hawaiʻi Department of Land and Natural Resources (DLNR)’s Division of Aquatics Resources and Hawaiʻi State Parks, and members of the Hui Loko network (Hawaiʻi Island fishpond and anchialine pool working group).

This symposium will bring experts together from around the world and across Hawaiʻi Nei to build and share knowledge, stories, and research on anchialine fauna, habitats, water chemistry and restoration efforts.

Past ISAE events have been hosted across the Atlantic seaboard but never in the Pacific region.

  • 4ISAE was hosted in Lanzarote, Spain (2018)
  • 3ISAE in Mérida, México (2015)
  • 2ISAE in Croatia (2012)
  • 1SAE in Mallorca, Spain (2009)

Previous statewide Hawai‘i anchialine pool symposia have been hosted on Hawai‘i Island in 2008 by the National Park Service at the American Association for the Advancement of Science (AAAS) Pacific Division Meeting and in 2016 by the DLNR’s Division of Aquatic Resources. We look forward to bringing these two diverse groups together for this upcoming 5ISAE event!

We are currently seeking sponsors and in-kind donations to support student travel stipends, marketing, and hospitality (field trips and food) for this event!  Please share this web page and beautiful flyer with whomever we may have missed in the anchialine world.

Me ka mahalo / with gratitude / muchísimas gracias / köszönjük / grazie / merci beaucoup,

Anchialine Galleries


Aloha from a pristine anchialine pool from Hanamanioa, Maui. This pool is home to many ‘ōpae huna (Palaemon debilis) aka “feeble shrimp”. Find out more info about this shrimp inhabitant.

Aloha from Hoʻonoua, a remote pool complex within the ahupuaʻa of Wai‘ōhinu and within the bounds of the coastal portion of the Kaʻū Forest Reserve.

One of the two larger pools in this anchialine complex is impacted with highly invasive golf-course grass (seashore paspalum) and the other with highly invasive fish (Mozambique tilapia). Hawaiʻi Wildlife Fund has been working to rid these pools of these particular pesty species by hand, net, shovel, bucket and trash-pump since 2007 in the hopes that the native ʻōpaeʻula shrimp (Halocaridina rubra) and native epiphytic plant (Ruppia maritima) or what uncle Piʻi calls mauʻu ʻōpae can return and thrive.

Shown here are a selection of photos of the northernmost pool in the complex, Hoʻonoua ʻakau, in 2018 and 2019 during various volunteer restoration workdays.

Learn more about this pool ecosystem during the upcoming 5ISAE event, and perhaps join us for a huakaʻi (fieldtrip / adventure) to this unique region.

Aloha from Lukiki, a named anchialine pool in the ahupuaʻa of Makalawena in the kalana of Kekahawaiʻole in Kona, Hawaiʻi Island.

This pool was modified and used traditionally by the kānaka (people) of Makalawena. This pool currently contains a healthy population of the native seagrass Ruppia maritima, an important component of the anchialine habitat as it provides shelter and foraging area for ʻōpaeʻula and other fauna.

Hawaiian anchialine pools come in many shapes and sizes. You will have the opportunity to learn more about these fascinating ecosystems during the 5th International Symposium on Anchialine Ecosystems in November 2022. We hope to see you there!

Hawai’i Island has the highest concentration of anchialine pools in the world!

Attendees of the 5th International Symposium on Anchialine Ecosystems will have an opportunity to visit some incredible anchialine pools on the island during the symposium.
