Report of Working Group 23 on Comparative Ecology of Krill in Coastal and Oceanic Waters around the Pacific Rim

Abstract

In October 2007, the PICES Working Group on Comparative Ecology of Krill in Coastal and Oceanic Waters around the Pacific Rim (WG 23) was established under the direction of the Biological Oceanography Committee. This report brings together reviews of the state of knowledge of Euphausia pacifica and Thysanoessa species in the six PICES member countries over the time period from 2008 to 2012. The chances to conduct euphausiid research varied amongst countries, but PICES scientists rose to the challenge and made the most of the opportunities available to them. From mining euphausiid data out of existing time-series data sets to conducting live euphausiid experiments (using the protocol available on the PICES website, http://www.pices.int/projects/Euphasiid/euphasiid.aspx), WG 23 members generated new and interesting data on euphausiids throughout the North Pacific.
