Welcome to fishlarvae.org!

These web pages present an overview of the research activity being conducted at the Norwegian Institute of Marine Research by Howard Browman, Anne Berit Skiftesvik, Caroline Durif, Reidun Bjelland, David Fields, and our students, Post-Doctoral Associates, Research Associates, and Collaborators. We also provide some general information on the early life stages of marine fish and shellfish, and links to other web pages that might be useful to those interested in such matters (under the RESOURCES menu item).

Lumpfish working group meeting

7-9 February 2017 – The working group on lumpfish (WGlump) was hosted by Caroline Durif, in Bekkjarvik, Austevoll, Norway. Participants were Rasmus Hedeholm (Greenland Institute of Natural Ressources, Greenland), James Kennedy (Marine Research Institute, Iceland), Halldor Olafsson (BioPol, Iceland), and Johanne Gauthier (DFO, Canada). The group discussed recent updates on lumpfish (Cyclopterus lumpus) research and compared the different methods of assessments of lumpfish wild populations across its distribution area which extends from Canada to the Baltic and the North Sea. Lumpfish has traditionally been exploited for its roe, but in recent years juveniles have also been used as delousing agents in Norwegian salmon aquaculture.

Howard Browman serves as external examiner at Ph.D. defense

17 January 2017 – Howard Browman travelled to the Research Institute in Semiochemistry and Applied Ethology (IRSEA) in Apt, France, to act as one of two external examiners for the Ph.D. defense of Cyril Delfosse. The other examiner was Professor Donald Broom from Cambridge University. The thesis was entitled, “Methods for stress assessment and management in farmed salmonids: sanitary, zootechnical and environmental implications”. It was submitted to the Institut National Polytechnique de Toulouse for the degree of Doctor of Philosophy. A large part of the work dealt with identifying a pheromone that reduces the attachment of the parasitic salmon louse onto its salmon host (the “Sealice Copepodid Attachment Inhibitor Semiochemical”), and this may lead to a future collaboration between IRSEA and us!

ISOACC-2 - Hong Kong

5-9 December 2016: Howard Browman, Anne Berit Skiftesvik, Caroline Durif, David Fields and Steve Shema participated in the Second interdisciplinary symposium on ocean acidification and climate change (ISOACC-2) at the University of Hong Kong. Howard presented two talks: “Applying organized skepticism in ocean acidification research” and “Fake news: the real life dangers of over-interpreting your results” and also summarized the conference. David presented the poster, “End of the century CO2 concentrations do not have a negative effect on vital rates of Calanus finmarchicus, an ecologically critical planktonic species in North Atlantic ecosystems.”

Lend your support to the "eeluminium" crowdfunding initiative

7 November 2016: An exciting crowdfunding campaign – “Eeluminium”  – has been launched. Eight researchers from Belgium, the Netherlands, France and Norway (Caroline Durif) are developing a project to look into the effect of aluminum in the decline of the European eel. Once very abundant in European rivers, the eel population dramatically declined by more than 90% so that eels are now considered as critically endangered. The causes of this rapid decline are unknown. Our recent data point to a new possible cause: aluminum.  We need your support for analyzing aluminum content of eel ear bones (otoliths) collected over the last 100 years as to validate this hypothesis. If proved true, this could serve as basis for developing effective means for restoring the eel population.  Any donation, even very small, could contribute to our project, and finance costly analyses using laser-ablation based inductively coupled plasma mass spectrometry.
