Seminar 27 March: Capelin reared in different temperature scenarios and the effect on growth, survival and maturity across temperatures.

On Thursday, 27 March at 12.30, a seminar will be held at the Marine and Freshwater Institue (MFRI) called: Capelin reared in different temperature scenarios and the effect on growth, survival and maturity across temperatures. Einar Pétur Jónsson, a PhD student at MFRI, will give the talk in English. 

 

Capelin (Mallotus villosus) is an arctic and subarctic pelagic fish species that plays a key-role in subarctic ecosystems in both Atlantic and Pacific Oceans. Capelin has an important keystone role in the ecosystems it inhabits, and a high commercial value for various nations. It is a food source for several species sharing its ecoregions, including the Atlantic cod (Gadus morhua) which is the commercial species with the greatest value for the Icelandic economy.

Observational studies and species distribution models suggest that capelin has a narrow thermal range and that its distribution and dispersal pattern is sensitive to changes in temperature, which in turn has significant ecological and economic repercussions. Iceland-East Greenland-Jan Mayen capelin was recently reared from hatch to adulthood under laboratory conditions by scientists at MFRI in Iceland, opening up new possibilities for experimental studies on capelin, including this one. The objective of this study is to evaluate the performance of captivity-reared capelin at different temperatures, specifically to gain insight into capelin’s response to ocean warming.

The seminar, which is open to everyone is held on-site at the MFRI´s headqueartes at Fornubudir 5 Hafnarfjordur, main lecture hall and online on Teams. The link is here. Note that the seminar will be recorded.
