Euphausiid crustaceans, commonly referred to as krill, are fast-moving, pelagic, exclusively marine, and found in all oceans generally below 50 m. While restricted to only 86 species in two families, the six largest-size species are abundant in higher latitudes and of commercial interest. Assessment of stocks and collection of specimens generally involves location using active-acoustic surveying and towed equipment from research vessels. Capturing live euphausiids for physiological work requires particular care. The appropriate treatment of specimens obtained depends upon the reason for their collection and a range of options are discussed
