Welcome to the website of the World Association of Copepodologists !

Copepods are among the most abundant metazoans on Earth and can be found almost everywhere there is water - from high-altitude lakes in mountain ranges, down to the depths of the ocean trenches. Copepods dominate the zooplankton, they are super-abundant in sediments, and they are parasitic on virtually every phylum of animals from sponges to chordates (including reptiles and mammals).


This website will help you find out more about this fascinating group of crustaceans.


The World Association of Copepodologists (WAC) is a nonprofit international organization whose purpose is to promote research on Copepoda by facilitating communication among interested specialists. Join WAC today!


The business of the WAC is conducted primarily at a triennial business meeting held during each International Conference on Copepoda (ICOC). Since 1987, the ICOC has been held at venues in Asia, Africa, North and South America, and Europe. The most recent (13th) ICOC was held in Los Angeles, U.S.A. in July 2017. This conference was organized by Julianne Kalman Passarelli at Cabrillo Marine Aquarium (julianne.passarelli@lacity.org).

The next conference will be from 2-7 June 2024 in Hiroshima, Japan.

The Local Secretary is Dr Susumu Ohtsuka from Hiroshima University. For more information, visit the 15th ICOC conference website: https://icoc15.hiroshima-u.ac.jp/home.html, Facebook  or Twitter

Join us for the e-ICOC!

Dear copepodologists,


We are very excited about the opportunity to host the online International Conference on Copepoda from July 25 to 29, 2022. e-ICOC is the first online meeting organised by the World Association of Copepodologists. The time that has lapsed since our last ICOC meeting in California – and for many of us the last time many of our fellow copepodologists could meet up – is coming up to five years. By the time the next ICOC will take place it will be seven years, implying that a generation of copepodologists will have retired by then and at least two cohorts of students will never have had the opportunity to participate in the most appropriate international scientific platform for disseminating their research. Due to the Covid-19 global pandemic having prevented the normal physical conference cycle of 2020, and the recent cancellation of the meeting in South Africa, the Executive Council of WAC endorsed our proposal to host a virtual meeting this year. This event will give priority to early-career researchers who need to present their work as part of their career milestones. The e-ICOC will be held in the Greenwich Mean Time zone, using the Zoom video platform.

e-ICOC is not a replacement for the normal in-person International Conferences on Copepoda. The cycle of these physical meetings is planned to continue from 2024 with Prof. Susumu Ohtsuka taking the lead in organising the next ICOC in Hiroshima, Japan. As during previously organised copepod conferences, e-ICOC will host the WAC Business Meeting during which members of the Executive Council will present the Society’s financial reports, overview of activities for 2017–2022, election of Officers, awards for best student presentations, and plans for 2022/2024.

As the conference will be online, registration fees are significantly reduced compared to the physical format, facilitating the attendance of more participants and enabling more inclusion.

Registration is open NOW – please visit http://e-icoc-2022.com for more details.

Looking forward to welcoming you all.

“The WAC Executive Council stands in support of all scientists. We are greatly appreciative of the organizers and committee members of the e-ICOC conference for their contribution to WAC. We feel that it is important that the international research community have unconditional support and that everyone feels welcome to participate in all aspects of WAC” (WAC Executive Council, March 2022)
