WGALES exchanges ideas, methodologies, and developments, and works on standardization of fish larva and egg (ichthyoplankton) surveys in the ICES area, as well as providing a platform from which to improve the assessments based on the surveys.

​​​​​​​​​​​​​​​​​​​​​The activities of WGALES are vital for the delivery of state-of-the-art ichthyoplankton surveys, ensuring high standards through quality assurance, and incorporating new techniques and developments for the future.  

Several ichthyoplankton surveys are carried out within ICES areas, all coordinated by their own expert group. In the past these groups worked on their own and there was little exchange of information between them. WGALES now provides a forum for discussion and dissemination on matters pertaining to spawning dynamics, ichthyoplankton biology, ecology, surveys, and egg and larval production methods. The group is also an interface for ICES Science Committee (SCICOM) and Advisory Committee (ACOM) for matters concerning ichthyoplankton surveys.​

Join WGALES meeting

The group is welcoming new members! Their next meeting takes place 17-21 October 2022 at Nausicaá Aquarium in Boulogne-sur-mer, France. The meeting is hosted by Ifremer

The meeting will cover three sessions: 

  • fish egg and larvae surveys throughout Atlantic regions
  • early life history ecology
  • maturation, migration and environmental cues for reproduction
In addition there will be afternoon workshops on: 
  • ichthyoplankton and zooplankton processing with imaging techniques
  • recent developments in reproductive ecology

View the draft meeting agenda.

If you are interested in joining the meeting either in person or remotely, please contact the group Chair Patrick Polte​.
